The Lair of the Dark Folk
A crumbling ruin at the ed of a dark, filthy alleyway hides a long, steep, winding stairway. Once leading to an underground hideaway of a minor noble, it now leads to the disgusting lair of a small tribe of dark folk; both dark creepers and a dark stalker reside here.
The walls, ceilings, and floors are coated and misshapen with trash and filth. The dark ones move quickly in their habitat; all others must move at half-speed or slower to avoid tripping or sliding. If someone falls, there is a 50% chance of an injury (1d4 + disease).
Ten creepers nest in the crannies of the main floor, while one stalker and six more creepers nest on the lower level.
