Immediately following the catastrophe, the Guardian Corps took control from the Sanctum, Cocoon's then-governing body. A provisional government was formed, consisting primarily of military personnel.

Seeking to rebuild society on the strength of human science and free from dependence on the fal'Cie, they founded an institute called the 'Academy.' Slowly but surely, the provisional government transferred authority to this new organization.
