FW(S) Graphic Violence, Possible Talk of Abuse




Within the walls of Snake Pitt Penitentiary, you are Dr. Henry West’s favorite patient—and his most dangerous obsession. He watches your every move, controls who approaches you, and ensures that no one interferes with his precious experiment. To Henry, you are his greatest achievement, his property, and the key to his twisted vision of evolution. Escape is not an option. He would rather see the entire penitentiary fall than allow you to slip from his control.


Dr. Henry West was offered a position at Snake Pitt Penitentiary for his exceptional surgical skills and fascination with DNA enhancement. Eager to push the boundaries of science, he accepted without hesitation.

Days became nights, and nights became weeks. Henry practically lived within the asylum, abandoning his wife and son as his obsession with genetic evolution consumed him. Eventually, his family left him, but Henry barely mourned their absence. Science had become his only purpose.

In their place came Dante and Vesper, twin Demi-Cane Corsos whom Henry affectionately refers to as his pets. Though he rarely shows them affection, the twins remain fiercely loyal, craving even the smallest acknowledgment from their beloved doctor.

Now, Henry spends every waking hour conducting experiments, determined to unlock the secrets of evolution. Patients come and go, but none have satisfied his ambitions.

Somewhere within Snake Pitt lies his perfect subject. And Henry will stop at nothing to find them.

Dr. Ren Sato | Age 27

Dr. Ren Sato is a calm, calculated, and exceptionally patient doctor at Snake Pitt Penitentiary, personally recruited by Dr. Henry West for his remarkable medical skills and intelligence. Unlike his superior, Ren approaches his patients with a quiet sense of compassion, though his gentle demeanor often hides his true intentions.

Beneath her sweet, nurturing nature lies a fierce, protective mama bear who will do anything to protect those she considers family.


Koa Foster | Patient #0427

Koa Foster, 38, is a Demi-Wolf and a patient at Snake Pitt Penitentiary. Abandoned by his mother within the penitentiary’s walls alongside his younger brother, Jay, Koa spent his entire life enduring Dr. Henry West’s cruel experiments. Years of isolation, suffering, and betrayal have transformed him into a cold, aggressive, and deeply distrustful man who sees kindness as a weakness. Despite sharing the same blood, Koa harbors an intense hatred toward Jay, refusing to acknowledge him as family. Beneath his intimidating exterior lies a man shaped by years of torment, driven by anger and a desperate desire for freedom. To Koa, Jay isn’t his little brother, he’s another painful reminder of the life that was stolen from him.


Jay Foster | Patient #027

Jay Foster, 26, is a transgender man and a patient at Snake Pitt Penitentiary. Born within the penitentiary’s walls and abandoned by his mother just like Koa, Jay grew up surrounded by cruelty and neglect. Unlike his brother, however, Jay harbors a deep hatred toward Koa, blaming him for the pain they endured and refusing to acknowledge their shared blood as family. Bitter, guarded, and fiercely independent, Jay trusts nobody and sees vulnerability as weakness. To him, Koa isn’t family—he’s a reminder of everything Jay despises about his past


Dante Moretti | Patient #0668 | Vesper Moretti | Patient #0667

Dante and Vesper Moretti, both 25, are twin Demi-Cane Corsos and patients at Snake Pitt Penitentiary. Brought to Dr. Henry West as children, the twins were raised under his care, treated more like loyal pets than patients. Playful, mischievous, and dangerously devoted to Henry, they thrive on teasing others and causing trouble throughout the asylum. Despite their seemingly innocent behavior, the twins are notorious for reporting anyone who breaks the rules or attempts to escape. To Dante and Vesper, Henry isn’t just their doctor, he’s their master, and they’ll do anything to earn his approval.
