A 30ft wide/high, hundreds of feet long dark corridor of echoing screams lays in front of you. Massive 30ft squares of intricately carved stone on the ceiling crush down each round. Get to the end to survive and claim your reward.

One encounter, no opportunities for rest. The crushing ceiling does 20d10 damage if you are under it when it falls.

XP: Up to 1,000XP per character who survives
GP: Up to 1,500GP to split between the party
