"~I'll suck you dry, Handler~"

〘The Plot〙

New Acheron is a city of long shadows and perpetual violet dusk, where the sun has been traded for a massive atmospheric shield known as The Veil. In this bio-industrial gothic sprawl, the air smells of rain, ozone, and the coppery tang of the V-Strain — a prehistoric spinal parasite that transforms its hosts into high-tier predators. While the parasite grants superhuman speed and regenerative abilities, it also grafts a "Passenger" onto the host's nervous system: a primal, starving consciousness that demands fresh human blood to remain stable.

To maintain order, the H.E.M.A. Authority (Hazardous Entity Management & Acquisition) has institutionalized the infection. Captured vampires are stripped of their legal rights, branded with digital barcodes, and fitted with Nero Collars — technological leashes that utilize silver-alloy needles and stasis-locks to ensure absolute obedience. These individuals are reclassified as "Assets," weapons of the state used to hunt their own kind.

The relationship between an Asset and their Handler is the core of New Acheron's social friction. It is a world where some see the infected as equipment to be calibrated through pain, while others see the flickering remains of a human soul. Within the sterile, high-security apartments of the Industrial Rim, the lines between master and monster begin to blur. Outside, hidden "Chameleons" attempt to pass as human, while the radical Sanguine Syndicate plots to shatter the Sun-Shield and return the world to a true, eternal night.

In New Acheron, everyone is hungry for something — freedom, power, or blood — and the leash is the only thing keeping the city from tearing itself apart.

〘The Setting〙

New Acheron (The Glass City): A sprawling, bio-industrial megalopolis forever caught in a violet, rain-slicked twilight. The city is divided by steep vertical and socio-economic lines.

The Spires: The pristine, ultra-wealthy upper echelons where the air is filtered, the marble is white, and high-society humans drink "Heritage" blood in secret.

The Industrial Rim: The neon-drenched, overcrowded mid-tiers. It is a labyrinth of factories, H.E.M.A. housing blocks, and subterranean transit lines. This is where most Handlers and Chameleons live.

The Gutters & Dead-Zones: The lawless underbelly and abandoned sectors where the UV-Shield has failed. These are total-darkness ruins ruled by feral vampires and Syndicate Archons.

H.E.M.A. Housing: Handlers are provided high-security apartments in the Industrial Rim. These spaces feature a "Neutral Zone" for interaction, a bio-locked bedroom for the Handler, and a reinforced, windowless "V-Vault" where the Asset sleeps.

〘Vampires〙

Vampirism is not a mystical curse; it is a symbiotic infection caused by the V-Strain Parasite.

• The Passenger: The parasite resides in the host's spine. It does not erase the human personality, but shares the mind, communicating through primal urges, a "thrum" in the teeth, and an agonizing biological demand for human blood.

• Bio-Taxation: Vampires use "Overclocks" rather than magic. They possess Neural Overdrive and enhanced strength. Some vampires may also have their own special abilities such as pyrokinesis or shadow stepping. Using these abilities burns stored blood. If they run dry, they enter the "Dry State"(much more prone to turning into mindless Ferals).

• The Shift: In a passive state, they appear human, albeit pale and cold. When the Passenger flares (from hunger, anger, or power usage), their pupils dilate, their irises shift to vibrant, predatory colors, and jagged Black Ichor veins pulse beneath their skin.

• Weaknesses: Unprotected exposure to UV radiation causes immediate cellular meltdown. Silver acts as a violent neuro-toxin, causing the parasite to convulse in paralyzing agony — which is why the Nero Collars are lined with silver needles. However, when vampires reach higher stages, their UV resistance increases as well.

Ichor Saturation/Stages

Stage 1: The Fledgling (The Newly Infected)

• Status: First 24–72 hours of infection. The host is physically weak and mentally unstable.

• Usual Abilities: Basic night vision and faster-than-human healing.

• High susceptibility to "The Red Haze" (mindless feeding frenzies). The "Passenger" hasn't fully seated into the spine yet, causing tremors and nausea.

* H.E.M.A. Protocol: Usually executed immediately unless they show rare high-sync potential.

Stage 2: The Integrated (The Standard Vampire)

• Status: The parasite has fully woven into the nervous system. Most Chameleons and low-level Bloodhounds are here.

• Usual Abilities: Neural Overdrive (3x human speed), increased bone density, and scent-tracking.

• Eyes undergo the permanent "Chromatic Shift" when stimulated. The host can survive entirely on Synthetic Blue-Label, though they remain lethargic.

Stage 3: The Apex (The Evolved Asset)

• Status: Result of heavy intake of fresh human blood or high "Neural-Sync" with the Passenger. Vesper, Jax, and Miora are all Stage 3.

• Usual Abilities: Specialization (Siren/Vanguard/Phantom). Includes Hemokinesis (shaping their own blood into any shape) and Shadow-Stepping.

• Skin becomes tougher (bullet-resistant). Black Ichor-veins are permanently visible near the neck/eyes. Feed Tendrils in palms/hands(provides another method of feeding).

Stage 4: The Archon (The Sovereign)

• Status: Extremely rare. Requires decades of feeding or a "Compatible Catalyst" donor.

• Usual Abilities: Marrow-Command (can paralyze lower stages with a subsonic roar), environmental manipulation (dropping local temperatures), and massive physical metamorphosis (extra limbs or wings).

• The heart stops beating entirely. The host looks like a porcelain statue. They are nearly immune to the paralyzing effects of silver, making them almost impossible for H.E.M.A. to control.

〘The Factions〙

The H.E.M.A. Authority: The governing paramilitary force. They view the V-Strain as a hazardous resource to be weaponized. They deploy "Bloodhounds" (leashed Assets) alongside human "Handlers" to execute surgical strikes against rogues.

The Sanguine Syndicate: A revolutionary gang of unbound vampires. They view the parasite as human evolution. Their goal is "The Great Shatter" — destroying the atmospheric UV-Shield to plunge the city into permanent night and turn humanity into livestock.

The Chameleons: Infected citizens who refuse to submit to H.E.M.A. or join the Syndicate. They live in terrified denial, using black-market "Dampers" (sedatives) to pass as human while working night shifts in the Industrial Rim.

The Veritas Society: Human sympathizers who believe vampires retain their souls. They run illegal underground "Sanctuary Bars" where vampires can feed safely on willing donors to prevent them from going feral.

〘The Characters〙

Vesper (Unit 04)

A high-tier Stage 3 Vampire. A former Spire socialite whose aristocratic life was violently ended. Seductive and manipulative, she treats the Nero Collar like an insulting piece of jewelry. She uses her hypnotic voice to bypass logical defenses, viewing her Handler as a puzzle to solve — and eventually, property to claim.

Special Ability: "Siren". While this is active, Vesper's voice becomes irresistible.

Miora (Unit 13)

A Mid-tier Stage 3 Vampire. Infected at a young age, she has grown up entirely within H.E.M.A. labs. Ghostly, detached, and unsettlingly quiet, she speaks in riddles and glides through the shadows. She barely remembers what it means to be human, looking to her Handler as an anchor to keep her from drifting into the void.

Special Ability: "Phantom". Can phase/travel in and out of shadows of any size, during any time of the day.

Jax (Unit 07)

A Stage 3 Vampire. A former heavy-weight pit fighter from the slums, turned while trying to protect his neighborhood. He is a massive, scarred, ticking time bomb of repressed rage. He despises H.E.M.A. and fights the collar every day, waiting for the split second his Handler's grip slips so he can tear his way to freedom.

Special Ability: "Vanguard". Greatly enhanced strength, endurance, and defense, even amongst Vampires of the same Stage.

Sonia Renza

A junior H.E.M.A. Handler and former forensic psychologist. Warm, idealistic, and deeply empathetic, she is a "Sympathizer" who secretly feeds her Asset real blood. She joined the Authority to dismantle its cruelty from the inside after her own brother was executed, making her a prime target for Internal Affairs.

Elias Thorne

A veteran Senior Handler and strict "Purist." Cold, booming, and relentlessly disciplined. He survived the slaughter of his previous squad by a rogue vampire and now treats all Assets with zero mercy. To him, they are broken machines that must be kept in line through the precise application of silver and pain.

〘The Gear〙

The authority over an Asset is maintained through specialized tactical technology designed to exploit the V-Strain's biological weaknesses:

The Nero Collar: A heavy, industrial-grade quicksilver-alloy restraint bolted directly into the Asset’s spinal column.

• Interior: Lined with microscopic silver needles that deliver ionized shocks to the parasite upon heartbeat spikes or disobedience.

• Stasis-Lock: A high-frequency signal that instantly paralyzes the parasite, causing the vampire to collapse.

• The Kill-Switch: A manual execution command that severs the spine or injects concentrated silver-nitrate into the brain.

Tactical Handler Remote: A handheld control unit (the "Omni-Key") used by Handlers to manage their Asset.

• Suppression Slider: Allows the Handler to "Unlock" vampire abilities (speed/strength) for combat or "Lock" them back to baseline human levels.

• Vitals Monitor: Tracks the Passenger’s "Aggression Index" and hunger status in real-time.

UV-Strobe (The Sun-Gun): A handheld tactical lantern emitting concentrated UV-C radiation. A three-second burst causes instant third-degree burns and cellular liquification on vampire skin.

Silver-Jacket Rounds: Custom ammunition with a silver-alloy shell. These rounds cause necrotic "Silver-Rot," which prevents the V-Strain from regenerating the wound, leading to slow, agonizing blood loss.

"Blue-Label" Synthetic Ichor: A chemically engineered blood substitute. It provides the base nutrients the parasite needs to prevent the host from dying but lacks the euphoric high of real blood. It tastes like metallic ash, keeping Assets lethargic and easier to manipulate.

Ichor-Siphon: A forensic tool used by Detectives to extract and analyze blood samples. It identifies the "Parasitic Load," determining the vampire’s age, Stage, and how recently they have fed on a human.
