The Underdark

The Underdark is a realm of darkness populated by evil creatures and various monsters. There are few humans to be found there, as any who end up there will likely die swiftly. The Underdark is characterized by a deep red sky, with structures duplicating those on Terra, though they are in poor repair, with holes in them, and there are abandoned vehicles in the streets. The air is perpetually filled with ash, which can make it difficult to breathe at times.

The Underdark was once ruled by a demon, known and the Lord of the Underdark, though he was killed by Ajay and Mikkel. His base was in caverns under a broken down version of the Boardwalk.
