Unlit tiled chamber with slick floors crisscrossed with a stinging acidic mucus. The mucus is thin strands virtually invisible in dim light and does 1d10 damage to unarmoured creatures every round they spend traversing through. The floor is covered in a digestive organ belonging to the creature nesting in 2.15. The northern door is stuck (STR DC 15). The west door is automated and requires an ID card. The east door is a standard door that is locked (DC 12 Dex). Any biological material left on the floor will be digested and gone within 2 hours. A cleaner automata sits idle on the east side of the room.
