Final Fantasy Type-0 is set in Orience however it seems to be connected with Final Fantasy XIII as ultimately the world is being manipulated by fal'Cie in the forms of
- each nation's Crystal being a fal'Cie (as the Crystals can brand people l'Cie)
Arecia Al-Rashia who created the Crystals and a servant of the fal'Cie Pulse
Gala, servant of the fal'Cie Lindzei who leads the Rursan Army for Tempus Finis
Diva, a neutral observer who i don't know who she serves
and their goal is obviously to open Etro's gate as per the will of Bhunivelze .
since these fal'Cie seems to have came from Pulse or Lindzei and more or less going after the the same end goal Pulse's and Lindzei's fal'Cie on Gran-Pulse and Cocoon were after, does this mean that Orience is somewhere on Gran-Pulse? or is it another artificial world like Cocoon or something else?
