Promathia (プロマシア, Puromashia?), from Final Fantasy XI, is known as the Twilight God, and is Altana's evil counterpart: faceless, and bound in chains he reportedly bound himself in. His reasons are unknown, but are revealed through the plot of the expansion pack Chains of Promathia.
Promathia was the god responsible for condemning the Zilart for attempting to open the Gates of Paradise, and called upon Bahamut to strike down their city made as a gate to the gods: Al'Taieu. Shortly after this, Altana wept the five divine tears that turned into the races of Vana'diel. However, Promathia made sure that this time the races would be preoccupied with something else to stop them from opening the Gates of Paradise. So, he created the beastmen to create eternal conflict between the great nations and people of Vana'diel. To complete his reign, Promathia seeks his own resurrection as the "Keeper of the Apocalypse," and his death, an event that would cause every soul in Vana'diel to return to him as he dies.
