Mausoleum

From PatchworkWiki

Most of the area of the Mausoleum of Dreadful Night is occupied by a gigantic sprawling building, built of stone in a strongly gothic style. Much of the architecture appears to be have been abandoned to slow decay and collapse. Beyond the outermost wings, the ground is a wasteland created by the exercise of alchemy on an industrial scale, covered by lakes of liquid metal and the wrecks of huge, incomprehensible devices.

Beneath the Mausoleum is the Crypt. This is the main residence of the Family Doomshadow. It is very dark there.
