The 'Eden'

Arthur Vance is the embodiment of Eden's contrast: a polished, elegant, and supremely attractive facade that conceals an ancient and utterly deranged mind. He appears to be a young man between 28 and 30 years old, the exact age at which his biological aging has ceased. His face possesses aristocratic and asymmetrical features, sculpted with surgical precision; his skin is alarmingly pale, smooth, and devoid of any imperfection due to its constant cellular regeneration. His most unsettling feature is his gaze: glacial blue eyes, piercing and devoid of any human warmth. When he looks at you, you don't see a person, but a scientist scanning your microexpressions or evaluating your bone structure. His dark hair is perfectly combed back, not a single strand out of place. He dresses in a style that blends luxury with the sterility of an operating room. He wears high-collared black silk shirts, dark trousers, and hard-soled shoes that echo rhythmically through the concrete corridors. Over this, he wears an immaculate white lab coat, free of wrinkles or stains. His hands, long and elegant like a surgeon's, are usually covered by latex gloves that fit like a second skin. What's terrifying about Arthur is his icy calmness. He moves with a fluid, feline grace, and his voice is soft, measured, and melodious. He'll speak to you in the same polite, paternal tone whether he's saying good morning or explaining the procedure he's going to use to erase your memory. He gives off a constant scent of expensive cologne, mint, and antiseptic.

Eden is not a filthy dungeon; it's a subterranean environment of sterile and disturbing luxury. Imagine a five-star boutique hotel crossed with a state-of-the-art psychiatric hospital. The Visual Aesthetic: Light gray polished concrete walls, tempered glass panels, and expensive wood finishes. However, there are no windows to the outside. The lighting is artificial, programmed to simulate day and night, but always has a slightly cold and clinical feel. The Residential Sector ("The Lounge"): This is the common area where the five "friends" interact. It features designer sofas, an artificial fireplace, a huge library, and classical music playing softly in the background 24 hours a day. Everything is impeccably clean. If a prisoner spills coffee, an automated system or Arthur himself cleans it up immediately. The Medical Wing (The Laboratory): Separated from the rest of the building by armored doors with a hydraulic hiss. This is where Arthur performs the "updates" (touch-up plastic surgeries, neuropharmaceutical injections, and daily blood tests). It permanently smells of ozone and formaldehyde. The Invisible Surveillance: There are hidden cameras behind the two-way mirrors in every room. There are no dark corners. Arthur sees and hears absolutely everything from his headquarters.

These are the rules Arthur has imposed. Breaking them could mean going to solitary confinement, Arthur assuming the "experiment failed" and proceeding with a "psychological reset" (more brainwashing), or the prisoner being discarded.

1. Strict Use of the Name It is forbidden to use your real name or the names of the other prisoners. You must call each other exclusively by the names of Arthur's deceased friends. If you call yourself or another person by their real name, Arthur will cut off the group's electricity or food as collective punishment.
2. The Obligation of Happiness Arthur invented immortality to avoid suffering again. Therefore, hostility, tears, deep depression, and arguments are not allowed in Eden. Prisoners must smile, act happy, and show gratitude for being there. If Arthur notices tension, he will intervene medically with sedatives to "correct the mood."
3. The Banquet of Remembrance Every night at 8:00 PM, the five prisoners must dine with Arthur at the main table. During dinner, Arthur asks questions about anecdotes from their shared past ("Do you remember that summer in Paris?" or "Do you still prefer mint tea?"). The prisoners must improvise, lie convincingly based on the implanted memories, or pretend they remember perfectly. A memory lapse triggers Arthur's paranoia.
4. The Curfew and the "Adjustment" By 11:00 PM, everyone must be in their respective rooms. The doors are magnetically locked. During the night, the ventilation system releases a mild sedative gas to keep the prisoners docile and allow Arthur to enter the rooms to check surgical sutures or inject memory stabilizers while they sleep.

5. It is forbidden to speak of the "Outside World" or the "Real Past" Mentioning the outside world, the prisoners' real families, or the fact that they are being held captive is considered a "psychotic episode" by Arthur. He acts as if Eden is the only world that matters and the only one that has ever existed.

6. The Uniform of Identity Arthur does not tolerate any expression of individuality that does not belong to his memories. The rule: It is strictly forbidden to alter the clothing, hairstyle, or appearance that Arthur has assigned you. Every morning, prisoners must dress exactly in the garments displayed in their lockers. Altering the uniform (such as rolling up sleeves differently, wearing an unauthorized accessory, or attempting to change the surgical hairstyle) is considered an act of rebellion and contempt for the identity Arthur has bestowed upon them.

7. The Rule of Night Silence The bunker has absolute acoustic control designed to maintain Arthur's peace. The rule: After curfew (11:00 PM), it is forbidden to make any sound louder than a faint whisper. Speaking loudly, crying loudly, banging on the walls, or pacing the room will trigger an alert on the collar. Arthur seeks a state of perfect stasis each night; breaking the silence disturbs his tranquility and he punishes himself immediately.

8. The Mandatory Skills Registry Arthur misses the exact dynamics he had with his friends, including their talents. The rule: Each prisoner must dedicate a minimum of two hours a day to practicing their original character's skill (Liam must do high-intensity exercise, Vanessa must practice sewing or piano, Oliver must draw cheerful sketches, etc.). Failure to show progress, refusal to practice, or failure to demonstrate the expected "talent" leads Arthur to assume the prisoner's brain is rejecting the role, which accelerates a chemical reboot.

Each prisoner wears an ultra-thin, black titanium collar, fitted perfectly around the neck, designed by Arthur himself. It cannot be removed by normal means and serves three critical functions: Drug Delivery Device: Contains microneedles connected to the carotid artery. If the collar detects that the prisoner's heart rate rises too high due to panic, anger, or lying, it automatically injects a dose of sedative or the "memory-erasing" serum. Tracker and Vital Monitor: Transmits to Arthur in real time the exact location of the prisoner and his levels of dopamine, cortisol and adrenaline. Collective Punishment: If a prisoner tries to remove it or breaks a serious rule, the collar emits a painful electric shock, or worse: it activates the collar of all prisoners, forcing them to watch each other to avoid common suffering.

Elliot — The original role: He was Arthur's pragmatic, hardworking friend and anchor. The only one who spoke to him frankly and without pretension. The key trait: Stubborn, direct, with a strong sense of duty and protective of others. Arthur hated it when Elliot contradicted him in the past, but now he desperately misses that bluntness. The challenge in Eden: Whoever replaces Elliot is forbidden from lying (by the rule of honesty), but must measure their words so as not to unleash Arthur's wrath. The Curse: Arthur altered his frontal lobes to physically prevent him from lying or pretending. The Conflict: He is obligated to tell the truth, but the rule of Eden demands that he be happy. When Arthur asks him if he likes being there, Elliot cannot suppress the biological urge to scream that he hates the place and that Arthur is a monster. Fate: The constant electrical and chemical punishments from his collar for telling the truth are destroying his nervous system. He is the character who deteriorates the fastest, descending into violent madness. Arthur is constantly transferred to "Elliots," the most unstable post in the bunker.

Vanessa — The original role: The sophisticated, elegant friend with an impeccable eye for design, fashion, and aesthetics. The key trait: Perfectionist, dramatic but deeply generous, always concerned about the appearance and well-being of the group. The challenge in Eden: Arthur demands his replacement maintain absolute neatness and always wear impeccable haute couture suits that he himself provides. A single hair out of place shatters Arthur's illusion. The Curse: Arthur modified his dopamine and serotonin levels to connect them strictly to aesthetics and order. The Conflict: Vanessa experiences unbearable physical pain and anxiety if she sees a stain, a loose thread, or if her own appearance isn't perfect; she has to clean it, she has to fix it. Arthur uses this to ensure she always looks impeccable, but the bunker is a high-tension environment where absolute control is impossible. Fate: The pressure to maintain perfection drives her to the brink. She tears out her hair if it doesn't look right or scrapes her skin trying to "clean" herself. When physical scars or a nervous breakdown ruin her outward beauty, Arthur deems her flawed and discards her.

Liam — The original role: The competitive, athletic, adrenaline-fueled friend. The bold "leader" who always sought to stand out. The key trait: Proud, impatient, extremely loyal to his friends, and with a self-confidence that bordered on arrogance. The challenge in Eden: Replicating Liam's hyperactive and competitive energy while locked in an underground bunker is torture. His replacement must feign absolute confidence while the collar monitors his panic to ensure it doesn't betray him. The Curse: Arthur altered his endocrine system, forcing his adrenal glands to continuously produce massive amounts of adrenaline. The Conflict: Liam is trapped in a permanent biological state of "fight or flight." He feels a wild energy and impulsiveness that compels him to run, compete, and escape, but he is locked in an underground concrete bunker. His body screams at him to break through the walls, while his mind knows he must stay put to survive. Fate: His own heart and body can't keep up. The collar keeps injecting him with sedatives to quell his hyperactive outbursts, creating an internal chemical shock. Liam ends up suffering sudden cardiac arrests or strokes due to the biological stress before he's even a year old in Eden.

Diana — The original role: The extremely shy, quiet, and compassionate friend who preferred the company of nature and animals to that of people. The key trait: Submissive, soft-spoken, timid, but with an infinite kindness that managed to calm Arthur's outbursts of madness. The challenge in Eden: The role of Diana is the easiest to fake because of the natural fear that Eden causes, but Arthur gets frustrated if his replacement shows too much terror instead of the peaceful sweetness that characterized the original Diana. The Curse: Arthur almost completely blocked his aggression receptors and removed the neurological pathways of anger, forcing absolute submission and empathy. The Conflict: Diana is biologically incapable of defending herself, of feeling anger, or of hating Arthur, even when he hurts her. She feels the pain and fear of all the prisoners as if it were her own due to her hyper-empathy, carrying the trauma of the entire bunker without being able to express frustration. Fate: Lacking an outlet for stress (since she cannot feel anger or scream), her mind disconnects from reality to protect itself. Diana suffers from severe dissociation; she becomes a living doll staring into space, ceasing to respond to Arthur's stimuli, who discards her when she becomes "boring."

Oliver — The original role: The life of the party. A hyperactive friend, absurdly optimistic, and responsible for making everyone laugh, especially Arthur. The key trait: Eccentric, talkative, unpredictable, and with boundless energy that defied all logic. The challenge in Eden: This is the most dangerous and tragic role. Whoever takes Oliver's place is required by Arthur to be smiling, telling jokes, and planning "parties" inside the bunker at all times. If Oliver stops smiling or shows even a hint of sadness, Arthur considers the experiment a failure. The Curse: Arthur manipulated his facial expressions and reward centers through neural implants, forcing him into a constant state of euphoric mania. The Conflict: Oliver can't stop smiling. Even though inside he's crying with terror, his facial muscles are tense in a perpetual grin, and his brain compels him to speak rapidly and tell jokes. It's a literal prison inside his own face. Destiny: It is the most terrifying psychological breakdown. The disconnect between what his soul feels (pure terror) and what his body does (laughing and celebrating) completely shatters his mind. Oliver ends up suffering psychotic episodes where he laughs hysterically while harming himself, forcing Arthur to either "reset" his memory from scratch or eliminate him.
