Wow, well so much for me helping others out... I still haven't finished the
game so you're way ahead of me.. as far as Ultima goes, here's my best:

It all begins at:

Pharos at Ridorana - Subterra
                            Abysaal

-------------------------------------------------------------------------------
Ultima, the High Seraph (Virgo)
[ULTMA]
-------------------------------------------------------------------------------
Previous incarnation: As the Nu Mou Totema in Final Fantasy Tactics Advance.
Also as the last boss/Virgo Lucavi demon Altima in Final Fantasy Tactics.
Altima is probably a mistranslation of Ultima.

First of all, why does holy-based Ultima keep holding her skirt up? It's not
like it's long enough to get in the cannon's way. Ultima was tasked with
leading human souls to heaven and helping them reincarnate. She was the
brightest and greatest of the Espers, and ambition led her to lead a
rebellion
against the gods with the other Espers. After her defeat, her light vanished
forever.
