This circular, subterranean chamber is quite large, spanning at least

thirty feet across. It is bare for the most part, its smooth stone

walls lacking any ornamentation whatsoever. In the centre of the room,

a dull iron disc around ten feet in diameter acts as a base for a

large, complex sculpture of stone. Strange runes have been etched in

the side of the sculpture, and multicoloured crystals imbedded within

it pulse with a strange rhythm.
