The Devil's Hand was originally a range of five mountains in the shape of a grasping demonic claw. The surrounding land was seemingly often covered in fog. Lucifer lived there, in the Devil's Castle.


After Lucifer's death, three of the mountains had collapsed, leaving the remaining two "fingers" ironically forming the peace sign. Much of the fog seemed to have blown away as well.
