A large round room filled with curved mirror surfaces and filled with blinding light every two rounds. Thrashing in the room is a frustrated light elemental. It regenerates 1d10 HP when the light pulses. It is unable to reach the door as the curved mirrors keep reflecting it back into the room. It's determined to escape by using the corpses of "meatfolk". Its pretty sure they are automatons, so feels no guilt for slaying them, though if communication can be achieved it will happy negotiate its escape in a lantern, which would not need oil any more. The pulses blind and the elemental does 2d6 damage when it attacks.
