Dr. Unne=Cid????

[Martyr]

Maybe one of the Leifnish is named Cid, but... Well maybe he died a long time ago, sometime before the airship was buried under the desert. His restless soul, in the form of a giant Eye which fumes with toxic death majiks, is left in the dpeths of the Ice Cave, to guard the only device that can revive the flying ship of the Sky Warriors!

After all... Garland, apparently, managed to turn the Sky Warriors into bats, and he doesn't even know magic. (Talk about some bad will saves) Cid knew that the next batch of heroes better be able to dodge death. And so he waits for them. And even after his spirit is defeated, it will respawn again and again! Until, ultimately, Chaos is defeated and the world is restored to normal. Cid will live forever, and you shall meet doom!

It makes sense.
Except for the "you shall meet doom" part.

Note: I know that it may not necessarily have been Garland who transformed the damn Sky Warriors.
