Clues
  • A tattered prison ledger with unaccounted prisoners and strange symbols scribbled in margins.
  • An encrypted journal of a guard who vanished mysteriously, detailing ghostly apparitions.
  • A strange, shimmering residue found on the walls, resistant to cleaning or erosion.
Dangers

  • Spectral prisoners manifesting as haunting figures attempting to silence intruders.
  • Falling into hidden trapdoors that lead to suffocating, inescapable pits.
Secrets
  • The prison was built over a portal to an ancient, otherworldly prison realm beyond human comprehension.
  • Some inmates are possessed by cosmic entities, driven mad or used as conduits.
  • The fortress itself is a construct that keeps an eldritch horror contained, and any damage risks unleashing devastation.
