Minwu is alluded to in several other installments, always as a great mage of lore.
Minwu wears a white turban with a white cloth covering his mouth, and wears a white robe with a gold pieces of plate in them. His turban and cloak are adorned with red gems and he is shown carrying a red and blue spiked shield. He has short hair, perhaps brown as shown by the sprites, dark brown skin, and blue eyes.
As a white mage, Minwu is naturally a person who takes care of the wounded, and is loyal to Hilda and acts like an adviser. He usually talks in a way that things "are by fate have to happen," so he may have an external locus of control. When he leaves to Mysidia, he acts like a person on a mission, because "his fate" is to obtain the Ultima Tome.
