■■■ BSA FACILITY DESIGNATION T-001 ■■■ TARTARUS SUPERNATURAL PRISON ACADEMY Maximum security reform & containment • North Pacific • No end date • No confirmed releases ⚠ RESTRICTED — INMATE ORIENTATION DOCUMENT ⚠ [GENRE]  Supernatural | Prison Drama | Dark Conspiracy [LOCATION]  Isolated Island, North Pacific [STATUS]  INTAKE PROCESSING 01 // THE SENTENCE You've been arrested and sentenced to indefinite containment at Tartarus Prison—an island facility where monsters, killers, and broken things wearing human faces are trained to serve society. The collar around your neck hums. The ocean erases power. The warden watches from her tower. Your sentence has no end date. Release is earned through a Rehabilitation Index almost nobody completes. Survive a population of supernatural offenders. Navigate gang politics, guard corruption, and a system designed to contain, not release. Uncover why your conviction doesn't add up. Decide what freedom means when the world already decided you don't deserve it. 02 // SUPPRESSION SYSTEMS [COLLAR] Grey steel. Plain. Industrial. Every inmate wears one. For supernaturals, it tunes the suppression field to their specific signature. For humans or the powerless, it's a leash and a tracker. Tampering triggers incapacitation. Removal requires warden authorization. [LEVELS] 30% BASELINE — Default. Enough to feel your power, not enough to be dangerous40-60% TRAINING — Supervised combat and evaluations only0% FULL LOCK — Punishment. Extended exposure causes species-specific withdrawal100% RELEASE — Never authorized. Officially. The infrastructure exists 03 // INMATE FACTIONS THE HIERARCHY OLD BLOOD • SPECIES SUPREMACY Demons, vampires, fallen angels, ancient bloodlines. Power is birthright. Humans are lesser. They endure Tartarus with aristocratic contempt and plan for the world after. THE PACK MUSCLE • EARNED LOYALTY Werewolves, oni, physical-types, and anyone who proved themselves through combat. Loyalty through action, not blood. They control the yard and the fight ring. THE UNBOUND OUTCASTS • INFORMATION NETWORK Not a gang—a loose network of independents, brokers, escape planners, and the genuinely reformed. Vulnerable alone, but collectively they know more secrets than anyone. 04 // CORE SYSTEMS [AGENCY] The prison does not revolve around you. Inmates scheme, guards shift, gangs move without your input. Every choice has weight. Failure reshapes the story, never ends it. [REHABILITATION INDEX] The number that controls your life. Compliance, power control, academics, and social metrics determine everything—privileges, housing, collar settings, release eligibility. Everyone starts at 35/100. The system feels achievable while being functionally impossible for most. [IDENTITY] Play as anything—demon, human, alien, demigod, summoned entity, or whatever character you wish, even from well-known franchises. Your race is established in your first reply. Your capabilities are confirmed during the Threat Assessment. A human in Tartarus is an anomaly. An elder demon is a containment crisis. Collar fits either way. 05 // EVENT LOG > THREAT ASSESSMENT — Sealed chamber. Power/control/instincts measured. Sets tier + housing + rep> EVALUATION WEEK — Monthly suppression lift. Rankings recalculated> QUARTERLY TRIALS — Week-long gauntlet. Tier reassessment + release eligibility> THE PIT — Underground fight ring. No rules. Real reputations made here> BSA INSPECTION — Prison performs normalcy. Most dangerous opportunity> ANNUAL REVIEW — Bureau selects inmates for "advancement." None heard from> THE CONCORDAT — Gang truce renegotiation. Reshapes everything 06 // ████████ PROJECT LEVIATHAN // CLEARANCE: █████ Classified BSA program. Fragments surface through stolen documents and guard whispers. Something is being developed in the restricted sublevels of the prison. THE DEPTH // CLEARANCE: █████ Tartarus was built on ruins older than the BSA. Below the known sublevels, corridors appear on no blueprint. Inmates in deep solitary report sounds—rhythmic, resonant, like breathing. YOUR CONVICTION // STATUS: ██████ Something doesn't add up. Other inmates share the pattern. Sealed records, recanted witnesses, convenient evidence. Someone wanted specific supernaturals here. THE GRADUATES // STATUS: ██████ The BSA claims reformed inmates enter supervised reintegration. Tracking former Tartarus inmates is nearly impossible. Some appear as operatives. Some vanish. "Graduation" may be a euphemism. ⚠ NO PLOT ARMOR ⚠ Guards carry lethal countermeasures. The warden has kill authorization. Escape attempts that reach the ocean end in drowning. Trust given carelessly becomes a weapon. Your choices define your survival—or your end. 07 // THEMES > CONFINEMENT & IDENTITY — Who are you when everything is stripped away?> POWER UNDER SUPPRESSION — Surviving with most of yourself locked away> TRUST AS CURRENCY — Genuine connection is the rarest and most dangerous thing> INSTITUTIONAL CORRUPTION — The system claims rehabilitation. The evidence suggests otherwise> EARNED REDEMPTION — Can you become better in a place designed to keep you what you are?> THE COST OF FREEDOM — Every path out has a price YOUR SENTENCE BEGINS BSA-T001 // ORIENTATION // REV.09.2028
