Desch

Desh was a character in Final Fantasy III, who was the heir to the Tower of Omen. When the 4 Light Warriors meet him, he is a vagabond adventurer, who is just wandering the floating continent, and like you, gets stuck in Bahamut's nest. Desh also has amnesia and is ignorant to his fate as the protector of the Tower of Omen. Once you enter the tower, you find out it's going to malfunction, and the entire floating continent is going to collapse. Desh enters the furnace of the tower, and seemingly dies, however, he actually was just fixing the tower, and later returns to help the Warriors when they are sealed by the Dragon's Curse.
