The party enters the castle of Palamecia and confronts Leon. However, the Emperor reappears in the throne room in a new demonic form, revealing he has returned from Hell with the intention of destroying the entire world. The party and Leon escape Palamecia Castle with the wyvern, as the castle is replaced with the palace of Hell, Pandaemonium. Leon agrees to help the group seal the Emperor away. The party travels to the Jade Passage, an underground passage to the underworld, and finds the portal to Pandaemonium, where they finally defeat the Emperor. Afterwards, Leon chooses to leave in response to the trouble he caused, though Firion assures him that he'll be welcomed back if and when he returns.
