Qui-Gon Jinn

Qui-Gon Jinn is described as a spirit (or a god, as he prefers) with red and white robes, and brown hair with a mid-length beard, and he is confirmed to have come from the planet Coruscant. In Episode I, he greets John Mihn to teach him psychic vision, though only receives John Mihn's name in the 20th chapter.

Thus far, he is described with a mysterious illness, which gets in the way of psychic vision training.
