Interdimensional Rift

The Void (or the Interdimensional Rift) is the location of the final battle in Final Fantasy V. It is also the place where all evil gains power from, and where the "ultimate evil" (Enuo) gave up his immortality in order to gain the infinate power housed there. His plan failed and he was engulfed by the Void.

Exdeath's grand plan is to gain dominion over the power of the Void, but as with the "ultimate evil" before him, in his final battle with the warriors of light, the Void engulfed him. While he continued to fight during this time, he had lost control of himself and was destroyed as much by the Void as by the warriors.

When Exdeath gained power over the Void late in the game, he merged the two dimensions of the world into one and then proceeded to absorb any cities that would prove to be a problem into the rift. The place where a castle once stood remains as a hole in the Void where the warriors of light can come and go freely before the final battle with Exdeath.

Exdeath also used the Void to send his servant Gilgamesh into exile.
