 As Crono's friends depart, the ruined Ocean Palace rises into the air as the Black Omen.The group turns to Gaspar for help, and he gives them a "Chrono Trigger," an egg-shaped device that allows the group to replace Crono just before the moment of death with a Dopple Doll (doing so is optional, and the game's ending will change depending on the player's decision in this matter).The party then gather power by helping people across time with Gaspar's instructions.
