New theories

[Future Esthar]

Perhaps Ultimecia's Realm (which our intrepid characters have to go to in Disc Four) is another dimension, or at least an alternate reality.

Exactly.It is the U dimension.
Edea is called Ultimecia on this dimension.
She married Seifer and gave birth to Rinoa.
Rinoa married Squall and gave birth to Zell.
Zell married Quistis and gave birth to Selphie which married Irvine.
They were a Dinasty of Centra Kings which came from another planet.
Seifer is the sun of Raijin and Fujin.

Uh.. FE... are we playing the same game?

Schala and the Time Devourer are from a game named Chrono Cross.I was just making a comparison.
