Vayne’s purpose was to free mankind from the Occuria, and worked with Venat to accomplish this goal. We defeat him, but also “destroy the Sun-Cryst, ensuring the Occuria will never crown another Dynast King”. And we recruited Espers to help with the tasks.
Beings of strange form and appearance made by the gods in ancient times. Favored with great strength and intellect, the Espers knew power far beyond that of men, but their power made them proud, and at length they sought to challenge the gods. Seeing this, the gods were angered and struck down their blessed children, and binding their souls and flesh with the Glyph of the Beast, they stole their freedom for all eternity. Now they are bound to live only when summoned by their Glyph, to serve whosoever called them forth.
But the Espers we took time to recruit us eventually become the Lucavi .
The Espers (召喚獣, Shōkanjū?, lit. Summoned Beasts) in Final Fantasy XII are powerful beings created by the Occuria. The Espers that join the player’s side are those spurned by their creators; twelve for having rebelled, and a thirteenth for being too powerful. Most of the Espers are based on the Lucavi in Final Fantasy Tactics or other past bosses of previous Final Fantasy games.
The Lucavi are demons in Final Fantasy Tactics working in secret under the cover of the Church of Glabados to revive their dead leader, Ultima the High Seraph. There are at least seven Lucavi, though one of them, Elidibus, is not necessarily connected to the other six.
We freed Ultima.
Masterpiece among the scions created by the gods, and the mastermind of the plot to rise against them. Prior to her betrayal, she was tasked with guiding souls to heaven and aiding in their reincarnation. Called the High Seraph for her angelic wings of glimmering gold, yet it was on wings of deepest black that the tainted angel Ultima rose against the gods. Since her fall, her heart is without light, and impossible to know.
She becomes the leader of the Lucavi, High Seraph:
A being that has been set free from the laws that govern creation, surpassing pedestrian concepts of morality.
All of these problems started after Ashe and Vayne decided they’d break free from the Occuria.
Many thousand years ago, all-powerful beings looked down upon the land, and their rule was absolute. They commanded all things on the earth. All was done according to their will. Then one day they withdrew behind the walls of a great city of their own making, disappearing from history’s stage. In the vacuum left behind, Ivalice fell into chaos, until the march towards a new age finally began.
…did we do the right thing in Final Fantasy XII?
