The Haunted House of Sokoloff is a large abandoned manor whose decay has become physically unnatural. Empty bedrooms, halls and service spaces are threaded with strange flesh-like thorned vines, while books, corpses and skeletal remains interrupt what was once a respectable family residence. Fog around the estate and the sheer number of rooms make the house feel isolated from the world outside before the party ever reaches the deeper sections.

With multiple floors and extensive interior space, the manor supports a full investigation rather than a single haunted-room encounter. Characters can search living quarters, compare disturbed and untouched spaces, follow the spreading growth and gradually assemble a picture of what happened to the Sokoloff family and staff. Doors, stairs and narrow halls keep movement tense, while larger rooms give supernatural threats room to become set pieces. The map works best when the house itself is treated as evidence: every altered room can reveal another stage of the disaster.
