Edge of Madness (混沌の果て, Konton no Hate?, lit. "Edge of Chaos") is an arena in Dissidia Final Fantasy and Dissidia 012 Final Fantasy. It is the site of the final battle with the game's final antagonist, Chaos, and in Scenario 000 with Feral Chaos.
Edge of Madness is a small, simple arena, a circular platform with Chaos's throne at one end, and the stage reaches very high vertically. In the background surrounding the arena 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.
In the stage's alternate version, the Bravery pool alternates between increasing and decreasing after a character performs an attack, decreasing at a faster rate than it increases.
The Battlegen item associated with the stage is Entropy's Birth.
In Dissidia 012, the Edge of Madness rests within a Gateway set in an active volcano on a floating island at the end of the Land of Discord, off the shore of Onrac above the approximate location of the Sunken Shrine. The Gateway bears the similar name "Edge of Discord".
The title of Report 12 is "Hill with View of the Water Temple", presumably referring to the Edge of Madness and the Sunken Shrine that would be nearby or under the island if it existed in World B. Based on this, the Edge of Madness would be the place where Garland, Chaos, Cosmos and Cid entered World B, and the cycles of war began.
Cloud comes to the Edge of Madness in the 12th Cycle and battles Chaos in an attempt to end the war with his death. However, Chaos is unfazed by his attacks and blasts Cloud with dark energy, expelling him from his service. However, Cosmos senses Cloud's dying wish - that Tifa be safe - and, seeing his benevolent heart, saves his spirit to be revived as one of her warriors in the next cycle.
At the end of the 13th Cycle, the Warriors of Cosmos arrive here to battle Chaos. Chaos is vanquished by their efforts, and they are teleported to safety as he is consumed in flame.
The Edge of Madness is the site of the storyline battles with Gabranth in both Dissidia and Dissidia 012. When the player receives the Moogle summon, it appears at the Edge of Madness if the player's character is a Warrior of Chaos.
