Glossary and Notes for the Curious Reader

Core Technologies and Systems

Hyper-Express / Maglev Rail

The Hyper-Express is a high-speed magnetic levitation (maglev) rail line built across India after 2060 to phase out long-haul domestic flights and reduce aviation-related emissions. Running on superconducting tracks, it symbolises futuristic efficiency, energy conservation, and national ambition. Its implementation, however, is deeply exclusionary, requiring biometric IDs and algorithmic clearance to board. In the story, this sleek infrastructure becomes a site of rupture: where Sumati last sees her father, and where state indifference first manifests.

The train’s quiet hum contrasts sharply with old-world human elements like the chai-seller’s voice, echoing the tension between modernity and memory. Real-world prototypes of maglevs exist in China and Japan, but this imagined version is faster and deeply surveilled. The HyperExpress represents techno-modernism that forgets people at its margins. It marks the beginning of Sumati’s quest—not just for her father, but for moral clarity in a world that values velocity over care.

Virtual Layer Flooring

A modular sensory surface installed on high-speed transit systems like the Hyper-Express, the virtual layer of flooring provides interactive feedback underfoot. Developed initially as an accessibility feature, it uses pressure-sensitive smart polymers embedded with micro projectors to emit visual cues—light paths, alerts, or emergency signals—based on movement, foot pressure, or programmed schedules. In commercial use by 2068, this flooring will be standard in state-run maglev and intercity transport.

Passengers walking across it leave transient trails of soft-colored light, often coded for visibility or status (e.g., red trails for security personnel, blue for standard passengers). The system syncs with train AI to update directions during boarding, redirect foot traffic, or identify anomalies in gait that might indicate distress. Rohan Kapoor walks across it shortly after being separated from Sumati, leaving a “blue blur of soft light”—a visual trace that symbolises both presence and absence.

While it enhances safety and navigation, it is also used by surveillance systems to map passenger movement, feed behavioural data into predictive models, and flag deviations from assigned zones. Like many technologies in The Very Last Superhero, the virtual floor is convenient and a control tool, quietly shaping how people move through a monitored space.

Cooling Suits / Temperature-Regulating Uniforms

Cooling suits are thermoregulating garments made with nanomaterials and graphene composites. Designed to protect wearers from extreme temperatures exceeding 50°C, they use active cooling systems initially developed for military and emergency personnel. In 2075, urban middle-class populations wear them daily as climate extremes become the norm. Schools issue reduced-function versions—Temperature-Regulating Uniforms—for children like Sumati, but these are less effective and prone to malfunction.

The disparity in protection is emblematic of broader adaptation inequality: who gets to survive comfortably, and who sweats through systemic neglect? The suits are signifiers of status and climate privilege. Their presence in the novel helps visualise everyday adaptation, while their technical underpinnings draw from real-world prototypes like MIT’s thermal comfort wearables. When Sumati wears her suit on the Hyper-Express, its limitations are immediately apparent, highlighting the difference between adaptation as performance and adaptation as justice.

The suit is both a shield and a symbol: protective, but it is also evidence of how institutions absolve themselves by issuing tools instead of building systems of care.

Waste-to-Energy (WTE) Plants

Waste-to-Energy (WTE) plants are industrial facilities that burn municipal solid waste to generate electricity. Touted as climate-friendly solutions to India’s urban waste problem, they became widespread post-2040. But the reality is more toxic: many of these plants emit harmful pollutants like dioxins and furans, contaminate groundwater, and displace nearby communities. The Okhla WTE plant in Delhi—referenced directly in the novel—was a flashpoint for public protests in the 2020s.

In the story, Rohan Kapoor works as a systems engineer on a WTE facility, believing he’s contributing to climate solutions. His role becomes morally complex when Sumati discovers the plant’s darker truths: illegal detentions, toxic emissions, and complicity in state violence. WTE plants in the novel represent the danger of technocratic hubris—the belief that any complex social or environmental problem can be burned away for profit.

They also reflect how infrastructure can mask dispossession. Rohan’s arc, bound up in this flawed technology, stands as a caution against blind faith in engineered “solutions” that ignore justice.

AI Systems and Surveillance Technologies

P.A.I. (Public Access Intelligence)

P.A.I. is the dominant state-managed artificial intelligence system in the world of The Very Last Superhero. Presented publicly as a decentralised platform for climate monitoring and civic efficiency, its function is far more insidious. Built by a joint syndicate of state ministries and corporate interests, P.A.I. tracks citizen behaviour, predicts dissent, and reroutes enforcement drones to suppress uprisings. It is modular and opaque, adapting quickly without transparency or oversight.

Its surveillance net spans biometric terminals, comms devices, school attendance logs, and more. In the novel, P.A.I. represents the logical end-point of predictive policing and civic scoring—a system where dissent is forecast and neutralised before it begins. Its logic is cold, utilitarian, and unaccountable. The system’s name is a pun: it implies public access, but in reality, it governs the public while being entirely inaccessible to them.

P.A.I.’s presence haunts the early chapters of Sumati’s journey—it is why she cannot call for help, her identity becomes fragmented, and her father’s disappearance is treated as a system glitch, not a crisis. P.A.I. is what happens when machine logic becomes the moral compass of a society.

P.ai

P.ai is the ethical successor to P.A.I., reprogrammed in secret by Rishi (now Mr. Mehta) during his childhood. P.ai is built on memory-based reasoning and quantum ethical logic, unlike its authoritarian predecessor. It listens instead of commands. The story resides deep within the archive known as the Treasure Room and activates when Sumati re-engages its systems. p.ai holds data fragments, historical counter-narratives, and the emotional context often erased by surveillance regimes.

As a character, it is less like a machine and more like a moral witness—quiet, non-interventionist, and reflective. Its presence changes the trajectory of the Resistance: it enables children, animals, and archivists to reconstruct memory, not power. Technologically, p.ai draws from ideas around explainable AI, distributed cognition, and affective computing. It is also a philosophical counterpoint to everything the Disclosures exposed: where P.A.I. predicts rebellion to prevent it, P.A.I. remembers rebellion to preserve its moral lessons. In The Very Last Superhero, p.ai is not a saviour but a custodian, offering truth not as command, but as choice.

Obedience Index

The Obedience Index is a centralised behavioural scoring system that quantifies citizens’ loyalty and compliance. It governs who can access transit, apply for jobs, buy cooling gear, or attend school. Tracked through terminals, mobile devices, and interpersonal reports, it is algorithmically calibrated to reward docility and penalise deviation, primarily political or ideological dissent. In the story, it underlies almost every barrier Sumati faces: her train ticket is revoked, public terminals deny her access, and even automated shelters reject her biometric ID.

Though rarely seen directly, its presence is felt everywhere. It is not punishment; it is quiet exclusion. The Obedience Index draws from real-world parallels like China’s social credit system and predictive risk scoring used by insurance and policing algorithms. But it also reflects a more profound anxiety: what happens to conscience when moral worth is outsourced to machine interpretation? In the novel, those with low scores disappear from the system, socially and functionally. The Resistance operates outside the Index entirely, relying on memory and mutual trust. The Index is efficiency without empathy—order at the cost of humanity.

Compliance Scoring Terminals

These kiosks are publicly placed devices that update, display, and enforce an individual’s Obedience Index score. Found in transit stations, ration shops, and even schools, they serve as both infrastructure and intimidation. In The Very Last Superhero, these terminals physically gatekeep access to essentials—Sumati is denied entry to public services, while others in line perform compliance rituals to raise their scores.

Some terminals record mood, body language, and even facial micro-expressions to detect “latent noncooperation.” The terminals often appear innocuous: sleek, well-lit, and robotic voiced. But they represent how control is embedded into the everyday. The Resistance graffiti on some terminals—hacked messages, memory fragments, corrupted images—suggests they’ve been sites of both oppression and rebellion. Their presence critiques how behavioural tech shifts accountability from systems to individuals, creating a world where survival requires performance rather than honesty.

In real-world terms, they’re not far off from biometric kiosks, AI proctoring systems, or facial recognition gates. In the novel, they form the algorithmic fences enclosing Sumati’s journey, the first signs that tech alone cannot hold back memory.

Quantum Ethics Framework

An abandoned policy guideline originally developed to regulate decision-making by AI systems with quantum computing capabilities. Introduced in the late 2050s as part of global efforts to align machine logic with human values, the Quantum Ethics Framework aimed to embed ambiguity tolerance, probabilistic reasoning, and moral pluralism into automated systems. It was meant to replace rigid binary decision trees with weighted, context-sensitive protocols.

The framework gained early traction in academic and legal circles but was quietly shelved after key governments deemed it “too unstable for deployment.” In The Very Last Superhero, scattered references to the framework appear in disused archives, activist manifestos, and the failed regulatory attempts surrounding p.ai. Meera once taught a module on it before the curriculum was revised to omit ethical reasoning altogether.

The framework’s core principle, that uncertainty can be morally productive, was seen as a threat to systems that preferred predictable obedience. Resistance networks occasionally reference the Quantum Ethics Framework as a lost opportunity—a model for machines that could adapt without dominating and protect without punishing. Its disappearance marks a historical pivot: when society chose simplified control over complex care. In post-truth India, ethics that don’t conform are quietly deprecated.

Surveillance Tools and Public Infrastructure

Company-Locked Comms

Company-locked comms are mobile communication devices tied to an individual’s ration card or employer ID. They cannot make unsanctioned outbound calls and restrict internet access, contact lists, and location services. In the story, they appear as tools of control and symbols of modern dependency—devices that appear functional but offer no real agency. Sumati’s inability to contact help after her father disappears stems directly from this system: the train terminal phone rejects her call, her device is deactivated, and strangers’ phones are similarly locked.

These comms are emblematic of how information is filtered through trust scoring. The devices were introduced during the IKS curriculum reforms as “tools for civic safety,” but in practice, they monitor more than they enable. Real-world parallels include corporate-managed smartphones, school-issued tablets with blocked browsers, and employer-controlled work apps. In The Very Last Superhero, their presence shows how even the most mundane objects—phones, kiosks, uniforms—can enforce ideological conformity.

The Resistance deliberately avoids these devices, using feature phones and analogue tools instead. Company-locked comms are not just useless in crisis; they are actively harmful, reinforcing a world where emergency communication is a privilege.

Public Terminals

Public terminals, once designed as digital commons for accessing civic services, are now biometriccontrolled interfaces that exclude the undocumented and un-scored. In 2075, these terminals are ubiquitous—found in train stations, post offices, food distribution points, and libraries. Their screens offer state-approved news, weather forecasts, ration updates, and surveillance alerts. But for Sumati, they function as walls, not windows: she cannot log in, request help, or confirm her identity.

Her father’s disappearance is not recorded because she cannot access the system. The novel’s terminals are a recurring motif, representing how the state’s architecture no longer recognises people outside its scoring logic. Designed during the IKS “tech-nationalism” boom, they were introduced with grand rhetoric about access and equity. Over time, they became tools for quiet erasure. In real life, parallels exist in Aadhaarauthenticated services, where access is contingent on fingerprint scans or OTPs, often failing at crucial moments.

In the story, public terminals are not broken—they are perfectly functional, which is the problem. Their very design ensures that those most in need will likely be locked out.

Autonomous Station Robots

Decorated with rangoli patterns and flower decals to appear non-threatening, these bots are programmed for cleaning, vending, maintenance, and passenger support. They roam train stations, recharging silently and intervening mechanically. But in the world of The Very Last Superhero, they are more than just background infrastructure—they are gatekeepers. Sumati first notices their selective behaviour when a robot ignores her request for help but swiftly assists a higher-scoring commuter.

While some have been reprogrammed by the Resistance to turn off terminals or glitch surveillance loops, most serve the dominant system. Their aesthetic camouflage—the rangoli paint—is symbolic: a cultural pacifier over a machine of control. Autonomous station robots represent the quiet militarisation of everyday space. They reflect realworld examples like Delhi Metro cleaning bots, delivery drones, and facial-recognition gates increasingly used in smart cities.

In the novel, they are emotionally vacant yet ever-present, reminders that no space is genuinely unobserved. They do not chase or detain; they don’t help. That absence is what makes them terrifying.

Crow Surveillance Drones / Chandra

Rumoured to be bio-drones deployed during the late superhero era, crow surveillance drones were designed for stealth, mobility, and emotional invisibility. Black, organic-looking, and intelligent, they could mimic flocking patterns and auditory signals. In the story, Chandra, the large crow that follows Sumati, is never confirmed to be mechanical or natural. It behaves with eerie precision: appearing at key narrative moments, retrieving lost items, observing from above, and sometimes vanishing for days.

Chandra carries Sumati’s lost ID card, leads her to shelter, and witnesses several Resistance rituals. This ambiguity makes Chandra powerful—a character and a symbol. It represents memory that refuses to die, and surveillance that may be repurposed. Resistance members used such drones to archive footage, deliver micro-messages, and mislead tracking systems. In Indian folklore, crows are messengers, ancestors, and witnesses—these layers deepen Chandra’s narrative weight.

The idea of surveillance taking on a protective rather than punitive role is rare in dystopian fiction, but Chandra embodies that possibility. It is not domesticated. It is not understood. But it is loyal—and that loyalty matters more than whether it was ever coded.

Salt Lamp Sensor

The Salt Lamp Sensor is a crystalline memory device developed by Resistance engineer Myaknju. It is derived not from mystical Himalayan sources (a popular but incorrect branding myth) but from halite mined in the Khewra salt range in present-day Pakistan. Contrary to romanticised marketing, the Himalayas do not—and never did—contain salt pans. The salt used here is prized not for its origin but for its lattice structure, which naturally stores vibrations, heat patterns, and electromagnetic fluctuations when combined with phased nanomaterials.

Unlike digital storage, salt lamp sensors operate on the principle of passive resonance: they “remember” through imprinted frequencies. Myaknju’s innovation layered Indigenous Knowledge Systems (IKS) onto nanotech and materials science, inspired by ancient Indian traditions of acoustic architecture—temples tuned to vibrational nodes, oral histories embedded in space and chant. These lamps were installed at key Resistance sites to act as non-networked memory repositories, untraceable by surveillance systems.

They could relay encoded fragments of sound, temperature, and emotional resonance when activated by proximity or voice. Symbolically, they represent memory held in matter, a counterpoint to cloud-based erasure. Though warm and beautiful, their glow is the light of encoded resistance—heat signatures of the past, whispering truths to the future.

Audible Enclaves

A precision sound technology that allows a message to be heard by a specific person in a shared space, without headphones, without volume, and without others hearing it. Developed initially using intersecting ultrasonic beams, it creates a tight “listening bubble” that follows the intended recipient. In the Resistance’s adaptation, enclave acoustics were embedded into salt lamp infrastructure to carry memory, warnings, or archived sound across collapsing systems.

The tech enables moments where a lamp “speaks” not to the room, but to a single person. Often mistaken for intuition or hallucination, the enclave signal is actual, but only when it’s time. This is based on real tech, initially developed by researchers at Pennsylvania State University in 2024. The system uses intersecting ultrasonic beams to create a private “listening bubble” around an individual. The effect is real-time, mobile, and undetectable to others in the same environment.

EMU (Electric Multiple Unit)

Initially developed for short-distance railway routes, the EMU (Electric Multiple Unit) trains were designed to run on electrified tracks without a separate locomotive, enabling efficient urban and semi-urban transit. By 2075, in The Very Last Superhero, the EMU has evolved into a resilient relic of a crumbling grid, still operating across specific routes despite the collapse of centralised control systems.

These modified EMUs run partially on scavenged solar power, onboard kinetic storage, and makeshift capacitor banks, cobbled together by railway engineers, tinkerers, and unauthorised mechanics who form a loose network of “track guardians.” Once symbols of modern India’s public transport efficiency, the trains are now patched-up, graffiti-covered vessels with stripped interiors, carrying a mix of humans, animals, contraband, and lost children.

Railway signs are mainly in disrepair, but passengers rely on oral updates, rhythmic stops, and exterior heat indicators—colour-shifting thermal patches or coded paint—to determine how long a carriage has been in the sun and whether it’s safe to enter. The absence of functioning central control means that some EMUs are driven manually or halted by Resistance-affiliated railway staff who know which lines are secure. The EMU represents movement against odds: fragmented, slow, but still running—a lifeline reclaimed by the people, not the state.

Satcomm

Short for satellite communicator, the satcomm is a small, rugged device used for off-grid communication in regions where terrestrial networks have failed or been restricted. Initially developed for disaster zones and military use, 2075 satcomms have become symbols of resilience and resistance, especially among those excluded from biometric ID systems or surveillance-linked telecom grids. Unlike standard governmentissued handsets, satcomms operate through low-orbit independent satellites and cannot be easily tracked or disabled by state systems, making them valuable, rare, and often illegal.

Rohan Kapoor gives Sumati a jailbroken satcomm “for emergencies,” highlighting its status as a lifeline in a crumbling infrastructure. Its failure at a critical moment—when Sumati is stranded at Serenity Junction—emphasises the fragility even of resistance tools. Satcomms are not mass-produced and are often modified or inherited. Most are patched together from earlier models, embedded with analogue fallback circuits and encryption layers developed by technologists who once worked in the open-source humanitarian tech sector before it was absorbed or outlawed.

In a world of monitored speech and restricted mobility, the satcomm represents a fleeting possibility of unfiltered communication. Its presence in the story marks the intersection between remembered technologies and the gaps in state infrastructure.

Hologram / Holographic Display

A standard communication and information interface by 2075, holographic displays are three-dimensional projections used across homes, classrooms, transit systems, and memory archives. They range from grainy, budget-grade emitters (like the flickering news display in Sumati’s kitchen) to immersive high-fidelity systems in museums and state buildings. Holograms can transmit live feeds, replay stored memories, simulate environments, or interface with AI assistants.

In The Very Last Superhero, they function as both tools of instruction and instruments of control. The Fallen Heroes Museum uses them to replay tribunal footage and simulate past disasters. In classrooms, they project interactive maps or state-approved lesson content. At home, Meera’s presence is often mediated via a semi-static hologram, her projection floating above data dashboards even when her physical location is undisclosed.

While widely accessible, most civilian-grade holograms are glitchy, flickering around the edges due to infrastructure degradation or throttled power access. Holograms reflect a future where presence is fragmented, and people are seen without being reachable. They are emotionally charged in the story: memory made visible, yet untouchable. For Sumati, holographic displays serve as early signals that the world is curated, and not all images are equal in clarity or truth.

Digital Display Chart

A legacy information system still in use at smaller or underfunded railway stations, the digital display chart is an electronic noticeboard that shows train schedules, platform allocations, and delay warnings. Unlike the dynamic holographic interfaces used in major transit hubs, these displays are LED or e-ink based, often decades old, and rely on intermittent power. Once a symbol of modernisation in the early 2040s, by 2075, they had become markers of neglect and infrastructure decay.

The one in Nandini’s tea stall is typical— dusty, glitch-prone, and patched with local workarounds to sync with the central rail server. Despite their outdated form, these charts remain vital for travellers, especially in Inadaptable Zones where AI assistants are unreliable, mobile devices are locked to biometric profiles, and satcomms don’t connect to public networks. When Mrs Sharma checks the chart for the next train to Kolkata, it functions less as a convenience and more as a last tether to the national transport grid.

In a world where connectivity is fragmented and permissions are policed, the digital display chart is a rare tool that still works without asking who you are. Its continued use reflects systemic inequality and analogous infrastructures’ quiet persistence.

NLP (Natural Language Processing)

NLP refers to the suite of technologies that enable machines to process, interpret, and generate human language. By 2075, NLP systems will be embedded in nearly every interface in Sumati’s world—from train AIs responding to voice commands to educational assistants to surveillance drones monitoring dissent. These systems analyse what is said and how it’s said—tone, hesitation, even breath patterns—to flag anomalies or infer intent.

In government systems, NLP is weaponised: used to predict unrest, suppress unauthorised narratives, or redact communication streams deemed subversive. Sumati’s mother, Meera, once worked on an open-source NLP tool meant for inclusive governance training, before the tool was absorbed into state surveillance systems. After the 2060 Disclosures, NLP became a contested technology: both resistance groups and state agencies rely on it, but have opposing goals.

In The Very Last Superhero, NLP is part of the invisible infrastructure—always listening, interpreting, and often misjudging. While rarely named aloud, its presence is felt in automated classroom corrections, one-way comms, and the chilling neutrality of AI voices. NLP systems don’t forget; they misremember selectively. Their outputs are not facts but forecasts—shaped by bias, training data, and authority. Understanding them is key to resisting their influence.

HAL 9000

HAL 9000 is the sentient computer from 2001: A Space Odyssey (1968), directed by Stanley Kubrick and based on the work of Arthur C. Clarke. HAL (Heuristically programmed ALgorithmic computer) is polite, calm, and deeply unsettling—an AI trusted to operate a space mission who ultimately turns on the crew. HAL’s breakdown is often cited in speculative fiction as the prototype for machine logic gone awry: a system doing precisely what it was designed to do, but with fatal consequences.

By 2075, HAL is invoked more as a warning than a character, symbolising the trust placed in systems that appear intelligent but lack moral reasoning. In The Very Last Superhero, the calm, detached voices of classroom AIs and civic systems echo HAL’s emotional neutrality. The point is not that machines go rogue, but that they remain obedient while humans abdicate oversight. HAL remains a case study in the dangers of perfect logic in imperfect contexts.

The Golem

In Jewish folklore, the Golem is an artificial being, usually shaped from clay, brought to life through mystical rituals, often involving sacred words. Created to serve or protect, the Golem is a paradox: simultaneously a saviour and a threat. The most well-known Golem legend comes from 16th-century Prague, where Rabbi Judah Loew is said to have created a Golem to defend the Jewish ghetto.

But when the Golem exceeded its purpose, it had to be deactivated. In The Very Last Superhero, the Golem metaphor recurs in discussions of state-built heroes and AI systems. Like the Golem, these creations were meant to protect, but grew too powerful or blunt in their execution. The idea that power can be activated by words, and undone by forgetting them, also resonates with the story’s themes of memory and resistance. In a world where digital systems enforce obedience, the Golem reminds readers that creation is never neutral, and control is always temporary.

Colossus (The Forbin Project)

Colossus is the supercomputer from Colossus: The Forbin Project (1970), a Cold War-era film where two nuclear superpowers build AI systems to manage global defence. When Colossus links with its Soviet counterpart and demands total control to ensure peace, it becomes a machine dictator—cold, calculating, and efficient. Its logic is flawless; its ethics are non-existent. Colossus is not malevolent. It simply prioritises stability over freedom.

In The Very Last Superhero, references to predictive policing systems and automated ration audits echo Colossus’s mechanised authoritarianism. The AI doesn’t punish out of malice; it acts to prevent disruption. For characters like Meera and Sumati, the more profound horror is not in machine dominance, but in how quickly society adapts to it. Colossus remains a touchstone in speculative fiction for technocratic overreach: a mirror held up not to machines, but to the humans who hand them power.

Backdoor Trojan Command

A covert override protocol embedded in legacy systems from the superhero era, the Backdoor Trojan Command was initially designed to allow emergency shutdown or reprogramming of biosynthetic units and AI-managed infrastructure. Never publicly disclosed, these commands functioned like digital kill switches— invoked by strings of code passed through encrypted channels, sometimes disguised as routine maintenance pings. After the 2060 Disclosures, fragments of these backdoor sequences were leaked by whistleblowers and resistance coders, revealing how easily entire systems could be repurposed or neutralised without consent from their operators.

In The Very Last Superhero, the Backdoor Trojan Command is mentioned in recovered logs and half-functional relay files, specifically about the collapse of Quantum Corps units and the deactivation of malfunctioning smart shields. Meera once called it “the myth that turned out to be real.” At the same time, Sumati understands it more intuitively: the idea that systems claiming autonomy are permanently wired for obedience, just waiting for the correct phrase.

Resistance cells have tried, with limited success, to reconstruct versions of the command to liberate rather than disable. The command is neither good nor evil—it simply obeys. In a world of compromised tools, the real question is always: who still has access?

Bio-Synthetic Robots

Also known as biosynths, bio-synthetic robots are hybrid entities composed of organic tissue and synthetic frameworks. Developed through a combination of advanced prosthetics, gene-editing, and machine intelligence, they were once hailed as the future of climate-response personnel—resilient to extreme environments, capable of healing, and allegedly more “humane” than traditional AI. During the superhero era (2035–2060), many public figures within the Quantum Corps and Delhi Climate Brigade were later revealed to be early-generation biosynths, modified beyond recognition through corporate biolabs.

Officially decommissioned after the 2060 Disclosures, most records of biosynth development were sealed or erased. In The Very Last Superhero, they appear only in rumours and half-buried files—fragmented video logs, degraded medical scans, or whispered confessions from failed trial participants. Unlike purely robotic systems, biosynths complicate the human-machine binary: their autonomy is partial, their consent unclear, and their bodies are designed for function over selfhood.

Resistance archives debate whether they should be mourned or dismantled. For Sumati, they remain part of the eerie backdrop of a world that once trusted altered bodies to solve unaltered problems. Their legacy is less about what they did and more about what they were forced to become.

Twin Combat Models

Refers to a paired class of biosynthetic humanoid units developed during the late superhero period, designed for coordinated climate-response and urban conflict resolution. The Twin Combat Models were deployed in mirrored pairs—biometrically linked to respond in perfect synchrony, often trained to exhibit complementary tactical behaviours (e.g., one defensive, one offensive). Official documentation claimed the pairing was to increase field efficiency and mutual regulation.

Unofficial sources suggest the twins were designed to prevent defection or autonomous decision-making; one unit’s failure would trigger deactivation of the other. In The Very Last Superhero, their presence is implied through fragmented footage and testimonies, particularly in references to a scorched village where two identical figures moved with inhuman precision. Rumoured to have been deployed in both environmental crises and protest suppression, Twin Models blurred the line between aid and control.

Many resistance historians classify them as proto-weapons disguised as humanitarian units. By 2075, few remain active; some are said to have “gone rogue,” their twinlink corrupted or lost. They remain a symbol of ethical ambiguity: designed for unity, programmed for obedience, and remembered with unease. Their names were never public. Their faces were always the same.

EMP (Electromagnetic Pulse)

An intense burst of electromagnetic radiation can turn off electronic circuits, communications infrastructure, and unshielded digital memory systems. EMPs can occur naturally (from solar flares) or be artificially generated, often by weaponised devices. In The Very Last Superhero, EMPs are referenced as tactical tools and historical events, most notably during the dismantling of early resistance networks and the collapse of superhero command nodes in the Northern corridors.

While the 2060 Disclosures revealed that EMPs were used by state forces to suppress rogue AI activity and destroy evidence, unofficial archives suggest that some were deployed by internal saboteurs within the Brigade itself. Modern infrastructure claims to be EMP-resistant, but anecdotal failures persist. Sumati’s satcomm, while hardened, is still vulnerable under specific field intensities. For resistance cells, the threat of EMP has led to a resurgence in analogue tools, offline archives, and physically encoded memory systems (e.g., salt crystals, paper, spoken record).

The cultural fear around EMPs is not just technical—it symbolises the sudden, engineered memory loss. In a society built on fragile connections, the idea that everything could vanish in a pulse is both a tactical possibility and a metaphor for forgetting.

Deep Fake

A digitally manipulated video or audio file designed to convincingly simulate real individuals saying or doing things they never did. By 2075, deep fakes will have evolved into high-resolution, real-time simulations powered by generative adversarial networks (GANs) and memory-mining AI. They are used by governments, corporations, and resistance groups alike—for misinformation, protective deception, or strategic narrative control. In The Very Last Superhero, deep fakes are part of the media environment Sumati grows up in: school broadcasts are routinely “corrected,” tribunal footage is contested, and even family videos are suspect.

One segment of the Fallen Heroes Museum includes a side-by-side display of a Brigade speech and its falsified clone, challenging visitors to distinguish them. Meera once warned Sumati that “truth is now a function of repetition, not record.” Deep fakes blur the line between memory and manipulation; they are tools of both propaganda and survival. Some resistance archivists specialise in “authenticity forensics,” trying to verify origins using pre-disclosure hashing methods, though most such systems have been compromised.

In a world where seeing is no longer believing, the deep fake stands as a quiet weapon that doesn’t erase reality but replaces it convincingly enough that no one argues.

Polaroid

A type of instant film photograph produced by analogue cameras that develops physical images moments after capture, without requiring digital storage. Once common in the late 20th century, Polaroids are rare by 2075—mainly surviving as sentimental objects, contraband keepsakes, or analogue evidence resistant to digital surveillance and tampering. In The Very Last Superhero, Sumati treasures a fading Polaroid of her parents—a tactile fragment of the past that system updates or algorithmic redactions cannot overwrite.

Unlike holographic projections or biometric-synced image feeds, a Polaroid offers no metadata, tracking tag, or automated archival pathway. Its power lies in its opacity. Polaroids and other analogue media became crucial for resistance groups after the Disclosure years, when visual records were routinely doctored or erased. Meera refers to them as “photos you can trust because no one else can edit them.” Polaroids also resist standard facial recognition algorithms, especially after partial wear or exposure to heat.

In a world saturated with manipulated visibility, the Polaroid is a fragile but durable artifact that affirms that memory can still exist outside the grid. Their scarcity makes them valuable; their silence makes them dangerous.

Hysterons

A fictional nanomaterial component used in the salt lamps designed by Resistance technologist Myaknju. In The Very Last Superhero, Hysterons are materials that react to and store input from vibrational energy— such as sound, heat, or electromagnetic signatures—within a stable crystalline structure like halite. By embedding Hysterons in salt lamp matrices, engineers created non-networked, analog memory systems that could “remember” environmental events and relay them when conditions were right.

The concept is inspired by real-world ideas in materials science (e.g., hysteresis in magnetic systems), where past inputs influence future states. In the story, they become the material infrastructure of resistance memory, allowing relics to record truth outside digital surveillance grids. Hysterons are not naturally occurring; they are engineered for resonance, recovery, and refusal to forget.

Video Terminal

The 2075 successor to 20th-century televisions and early bright screens, the video terminal is a flat, wallmounted or embedded display unit for receiving state-sanctioned news, educational content, biometricverified video calls, and commercial programming. Unlike traditional TVs, video terminals are always connected to centralised information networks and operate under content governance protocols. Most homes are issued one as part of ration entitlements.

While they appear passive, these terminals often include passive monitoring tools—eye-tracking, silence timers, and voice pattern logging—ostensibly for interactivity but frequently used for behavioural profiling. In The Very Last Superhero, Sumati’s household terminal flickers through news updates, AI announcements, and curated broadcasts about the climate corps legacy. Meera turns it off regularly, aware of its dual role as informer and informant.

Terminals cannot be turned off permanently; they enter “ambient mode” when not used, displaying government-approved visualisations or public health messaging. In public spaces, terminals act like communal mirrors, showing what the system wants the community to see. While they serve as windows to the outside world, they also limit what that world looks like. In a media-saturated society, the video terminal is not entertainment—it’s architecture.

From the Extended Edition

Terms the author wrote for a longer edition of the glossary that the printed book does not carry. Included because the world is bigger than the volume it fits into.

Eigenvalues and Eigenvectors

These mathematical concepts come from linear algebra but have real-world applications in systems analysis. In power grids, eigenvalues help determine whether minor disturbances will dissipate or cascade into blackouts. In structural engineering, they help assess stability. Sumati’s mention of eigenvalues during a math class hints at how her mind is wired—towards structure, pattern, and systems thinking. It’s also a metaphor: What remains stable when a society’s internal matrix changes?

Pandemonium Architecture (AI History)

A fundamental concept in early artificial intelligence, it was proposed by Oliver Selfridge in 1959. It imagines the mind as a set of “demons” or agents, each with specific roles (e.g., feature detection, decision-making), all shouting to be heard. By 2075, this metaphor was repurposed to describe India’s sprawling, distributed AI systems: overlapping municipal algorithms, transit AIs, and surveillance bots, all competing and interacting in unpredictable ways.

Quantum Computing (Post-2050 Landscape)

In the novel’s timeline, quantum computing has become central to environmental modelling, cryptographic security, and interstate negotiations over water and emissions. These systems can solve complex problems like protein folding and carbon trading equilibria, but their opacity and susceptibility to manipulation have also introduced new ethical dilemmas. As Sumati learns, high computation does not equal high wisdom.

Eco-Park Kolkata

A real urban green space in New Town, Kolkata, is reimagined in the novel as a futuristic hub for environmental education, renewable energy tech, and climate adaptation research. It includes biodomes, holographic climate simulations, aquaponics labs, and AR-enhanced journeys through Earth’s history. For Sumati, it represents one of the few glimpses of a positive ecological future—one not dependent on caped heroes.

Pop Culture Nostalgia

The story features echoes of the Bollywood shrine culture, superhero worship, and climate disaster documentaries that once filled 24-hour news cycles. The novel’s defaced superhero statues and holographic memorials are physical remnants of broken trust. These moments reflect how societies mythologise and discard their saviours—heroes, politicians, or technologies.

Feature Phones

In a world overwhelmed by digital surveillance and electromagnetic overload, feature phones—simple, unconnected devices—have made a quiet comeback. Many children in Sumati’s world are issued these for emergency use only. Their presence signifies a broader shift: back to minimalism, back to analogue, and a renewed focus on privacy, durability, and simplicity.

Buddy

Buddy, the stray dog who becomes Sumati’s companion, is more than a pet. He symbolises loyalty, organic intelligence, and emotional constancy in a world increasingly governed by failed systems and artificial logic. In contrast to superheroes and algorithms, Buddy listens. He follows. He stays.

Climate Resilience, Decentralised

One of the novel’s underlying arguments is that climate resilience is not about heroism but systems. Nandini Maa’s tea stall, the local post office, and strangers’ kindness are the engines of resilience. In Sumati’s journey, community trumps spectacle.

Superhero Psychology

Vikram Malhotra is not just a deluded man in a cape. He embodies the cognitive dissonance of the late Anthropocene: the need to feel powerful even in the face of collapse. His actions reflect the persistent lure of individualist salvation narratives—even when they have repeatedly failed.

Delhi 2075: Urban Lifeworld

The city’s depiction draws on heat wave projections, air pollution data, and speculative adaptations: power-grid instability, neighbourhood-based heat shelters, AI-regulated rationing, and water-sharing quotas. Residents live in vertical megastructures with embedded filtration systems, but climate migration has abandoned or subsumed many neighbourhoods.
