Edge of Madness is a small, simple arena, a circular platform with Chaos's throne at one end, and the stage reaches high vertically. In the background is a long staircase leading to the floor before Chaos's throne, as well as several gigantic swords that Chaos uses for his ultimate attack. Because the arena is used in Chaos's attack patterns, it is the only arena where players are able to face Chaos in any gameplay mode. The battlegen item associated with the stage is Entropy's Birth.
