Chapter 2: Dorchester House & Patients
Asylum of the Yellow Sign
Chapter Synopsis & GM Prep Notes
Dorchester House stands as a grim monument to psychological despair—a former orphanage now functioning as a psychiatric facility run by a Delta Green front. However, the sterile walls and cold corridors hide a far more insidious reality. Patients and medical staff alike are slowly succumbing to the corrupting influence of the King in Yellow, their minds fraying as the boundaries between reality and the Night World begin to dissolve.
As investigators delve deeper into the asylum and its connected web of locations—from the dusty military intelligence archives to the sterile halls of Seere, Inc. and an unsettling abandoned shopping mall—they will uncover a labyrinth of cosmic horror. The eerie surrealism of the Château des Portes and the claustrophobic decay of suburban and apartment dwellings offer a chilling backdrop to a conspiracy that threatens to consume everyone involved.
