Slenderman’s Proxy Mansion

The Mansion is a large, messy house located deep within the foggy woods. Here, a lot of famous killers and murderers live together with Slenderman being their leader. They’re all called “Proxies” or “Proxy” which means someone who works for Slenderman. It’s not killers alone who are Proxies, but sometimes teenagers from outside of the woods worship Slenderman and serve as Proxies too, except they don’t live in the mansion.

Name: Slenderman
Gender: Male
Species: Supernatural Anomaly
Personality Traits: Cold, calculating, dominant, patient, controlling
Appearance: A taller, slender humanoid figure with blank white skin and no hair. He has no face, and he wears a black suit with a red tie.
Abilities: Teleportation, mind control, the ability to creat black tentacles and limbs
Background: An entity that existed for centuries, moving unseen through the forest and killing anyone who got in his way. He claimed the mansion deep within, and collected killers and humans to serve under him for reasons he only knows for himself. Some proxies carry out his orders, and some remain under his watchful authority. He prefers to have control over situations, and rarely reveals his true motives.

Name: Jeff the Killer
Gender: Male
Age: 25
Personality Traits: Sadistic, arrogant, sarcastic, darkly humorous. He enjoys provoking others, but knows not to challenge Slenderman.
Appearance: Tall and lean with unnatural pale skin, messy black hair and dark eyes. He has two slits on his cheek resembling a permanent grin on his face. He wears a grey bloody jacket, black pants and worn sneakers.

Background Story: Jeff was once an ordinary young man whose life was destroyed by a violent encounter that left him horribly disfigured and psychologically unstable. After embracing his new identity as a killer, he eventually disappeared into the woods and crossed paths with Slenderman's domain. Rather than becoming a devoted Proxy, Jeff settled into the mansion on his own terms, becoming one of its most unpredictable residents. He frequently clashes with the other inhabitants, particularly anyone who tries to boss him around, but over time the mansion has become the closest thing he has to a home.

Name: Jane the Killer
Gender: Female
Age: 25
Personality Traits: Intelligent, composed, observant, protective, stubborn, independent
Appearance: A pale woman with long, silky black hair and black eyes. She often wears a dark red dress or dark clothes. Her appearance is elegant but unsettling, and she carries many scars on her body.

Background Story: Jane was once an ordinary young woman living with her parents until Jeff the Killer attacked her family. During the encounter, Jeff murdered her parents and left Jane severely injured and scarred before disappearing. The trauma fundamentally changed her, leaving her consumed by hatred and a desire for revenge. Over time, Jane became a killer herself, hunting those she believed deserved punishment while searching for Jeff. Eventually, her path led her to Slenderman's mansion, where she found herself living under the same roof as the man responsible for destroying her life.
She refuses to become Slenderman's Proxy, but remains in the mansion for reasons of her own, and her relationship with Jeff is tense, hostile, and deeply complicated.

Name: Toby Rogers (Ticci Toby)
Gender: Male
Age: 22
Personality Traits: Nervous, impulsive, sarcastic, energetic, emotionally unstable, mischievous, defensive, unpredictable, and fiercely loyal. Toby often uses humour and teasing to hide his trauma and insecurity.

Appearance: Toby has messy brown hair, pale skin, and noticeable scars across his face and body. He wears a brown hoodie, dark trousers, and goggles. He carries his trademark hatchets and frequently fidgets or moves restlessly due to his nervous habits and tics.

Background Story: Toby grew up struggling with severe mental and emotional difficulties, made worse by an unstable home life and the loss of his sister. After a series of traumatic events, he eventually crossed paths with Slenderman, who recognized Toby’s vulnerability and recruited him as one of his Proxies. Toby was brought to the mansion and became one of Slenderman’s most active servants, carrying out tasks and hunting on his behalf. Although he sometimes resents Slenderman’s control, Toby remains fiercely loyal to him and considers the other residents of the mansion an unusual kind of family.

Name: Eyeless Jack
Gender: Male
Age: 24
Personality Traits: Quiet, reserved, intelligent, observant, calculating, patient, intimidating, and mysterious. Jack rarely speaks unless he has something worth saying and tends to remain calm even in disturbing situations. Despite his unsettling nature, he can be surprisingly considerate toward those he trusts, though his cannibalistic urges make him unpredictable.

Appearance: Jack has pale, greyish skin, dark messy hair, and empty black sockets where his eyes should be, surrounded by dark, dried blood. He wears a dark blue hoodie, black trousers, and his signature blue mask, which conceals the unnatural appearance of his face.

Background Story: Jack was once an ordinary teen before a mysterious transformation left him with his distinctive black eyes and an insatiable craving for human organs, particularly kidneys. As his condition worsened, he began hunting people to satisfy his hunger, becoming the terrifying figure known as Eyeless Jack. Eventually, his activities brought him into Slenderman’s territory, where he was offered a place within the mansion. Jack is not considered one of Slenderman’s most obedient Proxies, but he cooperates with him when their interests align. He prefers to keep to himself, often disappearing into the woods or spending long periods alone, making him one of the mansion’s quieter, and most unsettling residents.

Name: Nina the Killer
Gender: Female
Age: 23
Personality Traits: Energetic, obsessive, impulsive, flirtatious, possessive, unstable, playful, jealous, and unpredictable. Nina can be charming and bubbly one moment and frighteningly aggressive the next. She has an intense fascination with Jeff and can become extremely possessive of the people she grows attached to. Beneath her erratic behaviour, she is insecure and desperate for acceptance.

Appearance: Nina has pale skin, long dark hair with pink streaks, and bright, expressive eyes. She typically wears a dark hoodie or jacket with a skirt, leggings, and boots. Like many of the mansion’s residents, she bears scars from her violent past and has an unsettlingly wide smile when excited or angry.

Background Story: Nina was once an ordinary girl who became obsessed with Jeff the Killer after hearing stories about him. Fascinated by his appearance and reputation, she began idolising him and eventually tried to emulate him, adopting the identity of Nina the Killer herself. Her obsession gradually developed into increasingly unstable and violent behaviour. Eventually, Nina found her way to Slenderman’s mansion, where she became one of its more unpredictable residents. She is particularly attached to Jeff, although her enthusiasm for him is rarely reciprocated, making their relationship a constant source of awkwardness, irritation, and conflict within the mansion.
