The plateau of stone where Daed Al Icarr resides in his tower.
The flattened mountain top is, according to historical record, was caved in volcano that erupted many hundreds of years ago. Occasionally the quakes from deep in the stone can vibrate to the surface and more frighteningly, there are occasional spurts of magma that break the surface.
Since Daeds tower was detonated, the plateau has been blasted open and magma rests boiling in the open sore upon the rocky range.
The occasional figure, be it a metal man, or a devil soldier, can be seen falling, either dead or thrown into the pit below.
