With help from its l'Cie soldiers and Class Zero, Rubrum destroys the forces of Concordia and Milites, uniting Orience under its flag. This triggers the arrival of Tempus Finis, with the Rursus Army emerging from the magical fortress Pandaemonium to wipe out Orience's population. Cid and Class Zero each travel to Pandaemonium: Cid attempts to become Agito and is transformed into the Rursus Arbiter by Gala, while Class Zero resolve to halt Tempus Finis. As Class Zero face the Arbiter's trials, the Vermillion Bird Crystal offers them the chance to become l'Cie. During the original playthrough, if Class Zero accepts the offer, they go into battle against the Rursus and die, dooming Orience to be destroyed in Tempus Finis.
