The backstory of Final Fantasy V is revealed in phases through cutscenes and interactions with non-playable characters. One millennium before the events of the main story, a powerful mage named Enuo imperiled the world using the power of an evil entity called the "Void". The people retaliated by using twelve legendary weapons to vanquish Enuo; however, the Void itself could not be destroyed. Consequently, the people split the world's four elemental Crystals into two sets, effectively creating two worlds. The Void then became sealed in a dimensional cleft between the two worlds. Nearly a thousand years passed without incident, and both worlds prospered due to the powers of their Crystals of Wind, Water, Fire, and Earth. New kingdoms and towns flourished, and travel by ship acted as a critical means of commerce and communication. However, a sinister force was stirring in the second world—ever since the Void incident, malicious demons had been sealed inside a tree in the Great Forest of Moore. The corrupted amalgamation of spirits emerged as Exdeath, the game's primary antagonist. When Exdeath attempted to claim the world for himself, a group of heroes called the "Four Warriors of Dawn" (Galuf, Xezat, Dorgann, and Kelger) sealed him within the first world using its Crystals, and peace returned for another thirty years.
