Cid of the Lufaine

Cid of the Lufaine is a minor character in remakes of the original Final Fantasy. He is mentioned by several townspeople in Lufania as the ancient creator of the airship.

Dissidia Final Fantasy expands his role in the original game considerably. Cid and his unnamed wife serve as foster parents for a young child named Garland. Cid is also stated to have been the researcher who created the systems for preserving Lufanian memories.

Some time after his son is taken by the army, he begins researching to create an ultimate weapon. In the meantime, his wife enlists in the army to try to rescue Garland, but refuses to go on further missions after slaughtering innocent civilians on her first assignment. She and Cid are both imprisoned as a result.

Cid's wife is shot in the ensuing jailbreak, and Garland disappears into a space/time rift of unknown origin. Cid disappears as well. When his wife returns to Lufania to tell her story before dying, Cid's Levistone is used to lift the town into the air, creating the Flying Fortress seen in Final Fantasy. She saves her memories and passes away.

What happens to Cid after this is largely unexplained, but he somehow becomes a god of the Dissidia universe. He finds Shinryu within the Interdimensional Rift, and makes a deal with him: in return for losing his body, Shinryu would recreate the world and revive its combatants after each war's end. Two lesser gods are placed in charge of the opposing armies, and at the end of each battle, the losing side would replace its god with one of its combatants.

Cid continues his research, believing this endless cycle of war to be the perfect opportunity to finish his ultimate weapon. When the warriors are summoned to the world of Dissidia, Garland himself joins the army of discord, and his alter ego Chaos becomes the god ruling it. Cid and Shinryu work to prolong the cycle for eternity, hardening Garland and, by extension, Chaos. Their eternal training would allow them to become the "ultimate weapon" Cid had been seeking, allowing him to get revenge for the loss of his wife.
