Dion is a human whose innate element is Air. He, like all temporary characters, cannot eat meat or install parts nor learn new spells. The equipment that is already equipped on him cannot be removed, but he can equip armor in areas he's missing. On both occasions he joins the party, he always comes equipped with strong weaponry and spells that may outclass the player's party. Because of this, he is both a formidable fighter and spell caster, making him one of the more powerful temporary characters.

Dion makes an appearance as a card in the card game.
Dion was a King in Laconia and husband of Amphithea, the daughter of Pronax. God Apollo rewarded them by conferring upon their three daughters, Orphe, Lyco, and Carya, the gift of prophecy, on condition that they should not betray the gods nor search after forbidden things. Dion erected a temple to Dionysus, who also visited his house and fell in love with Carya. When Orphe and Lyco tried not to let their sister consort with the god (thus breaking the restrictions imposed by Apollo), Dionysus changed them into rocks and Carya into a walnut tree.In Greek mythology,
