Bahamut the Fake was an ancient esper of enormous power, looking mostly like a huge metallic gray dragon, who had been in the Cleft at least since the Second Age. For the bulk of that time, it had remained in seclusion, living out of a cave high in the Loftarasa Mountains. Normally speaking, it only interacted with other creatures when they wandered onto its doorstep. But as time pressed on, he grew more and more angry at the way Espers had been treated.

He formed The Empire to lay waste to those who would oppose him, starting with Truce. He negotiated a contract with Deneb for her support and to conscript a gaggle of War Witches into his already-formidable army.

After a particularly grueling battle, Deneb attempted to negotiate a cease-fire. Enraged at her apparent cowardice, Bahamut The Fake attacked her, breaking the contract and lead to many people thinking he was transformed into a huge chunk of magicite.

It was later realized that this Bahamut was Fake and not the Father of the Eidolons, hence his title. An esper with a great deal of power perhaps, but the true Bahamut rests in the Lunar Subterrane waiting for worthy adventurers to test.
