Class Zero refuse the Crystal's offer and Rem is made a l'Cie in their place. Machina and Rem end up fighting each other in Pandaemonium: Rem is mortally wounded, and she and Machina turn to crystal. Weakened by the trials, Class Zero are initially unable to defeat the Arbiter. Machina and Rem's spirits give them the strength they need to defeat the Arbiter and halt Tempus Finis. Fatally injured, Class Zero spend their final minutes imagining their possible post-war lives. They are found by Machina and Rem, who have returned to human form and, along with the rest of Orience, are allowed to remember the dead. In a post-credits sequence, it is said that the Crystal States fall into turmoil as the Crystals lose their powers. Machina and Rem unite Orience and rebuild the world, and Machina records Class Zero's history before dying with Rem at his side.
