The Faultwarrens are a gauntlet of steep walls and deadly drops ruled by Titan, the fal'Cie believed to be responsible for managing the ecosystem of Gran Pulse. Creatures selected by Titan are pitted against one another in fierce battles with survival as their prize and predation the price of defeat.
Only the most formidable of creatures emerge from the Faultwarrens' trials alive, but those that do so go with Titan's blessing.
"Sulyya Springs" plays at the entrance of the Faultwarrens, and "Will to Fight" is the background theme that plays at all paths. "Desperate Struggle" plays as the background theme of Titan's Throne, though not necessarily at the battles themselves.
