In the Hall of the Mountain King #7

You are standing in the Central Cavern. A luxurious red carpet stretches from wall to wall but mind your step since some of it covers some very dodgy flooring - you don't want to fall through!

The ceiling is so high it has icicles hanging from it, which give off a pale otherworldly light.

You are not alone here. A clockwork mechanoid is pacing back and forth, struggling against the conveyer belt it is walking along. Is it a friend or foe?

What is the key to this place? It's getting stuffy; this room doesn't have the best air circulation. I'd hasten away before it runs out!
