Thatīs right.FFXIII confirms the veracity of some of my theories on FF8.
Confirmed theories:
Adel=Our characters magically fused together.
Headmaster Cid,president Deling and Mayor Dobe are shumis possessed by Doc Odine.
The world of FF8 is a "Time compressed" world.The reason the different eras look different is because of catastrophic events which changed the geography of the world.This is still hypotethical though.
The characters on FFXIII also seem to have a mysterious past in common which will probably be hinted at Versus XIII.
This probably will confirm my Centra Dynasty theory.
