Cavern of Marble and Brass

Cavern of Marble and Brass is a Deathtrap level.

Description
This gigantic hall used to be part of a larger underground residence, one of the secret palaces built by the royal family of a kingdom long extinct. The echoing, ornamental chamber must have been a ballroom or even a throne room, filled with music, laughter and clamor until the Trapmakers turned it into a mechanical and magical battleground, where the only sound now is the noise of the traps... mingling with the shrieks of dying monsters.
