about the origin of ultimecia (big big spoiler)

[Christmas]

Yes I answered.
When the characters reach the bottom of Lunatic Pandora it time travels.

This one isn't valid since you can't explain how do those sorceress just pop out of nowhere to attack you and since you explained they are actually Rinoa, Selphie and Quistis as I should say they look no where alike(you are going to say their looks deform due to black magic aren't you?) and there is more than just three sorceress you battled along the way.

Then we see all the sorceresses from the Centra dinasty in reverse chronological order.
Rinoa->Quistis->Selphie->Edea = Ulti.

The hair genetics certainly dun apply here.

The pandora goes to the past until it get´s to Ulti´s(Edea´s) time.
It´s logical to me.
Don´t you remember this is exactly the way the dinasty goes when the eyes genetics is taken into consideration.

You also have no proof of how is the Centra Civilization is like and what make you think they are ruled by kings and queens?

And if the pandora is the time machine that take them to Ulti's time, then where is the pandora after Squall and CO reached Ulti's time. WHy can't we see it?
