Warton was once a colonist hailing from Eol Sha, a volcanic planet; he was a male Human. He guided Luke Skywalker, a Jedi Master, to Gantoris, who was strong in the Force, so he could join the new Jedi Academy.
In 11 ABY, Warton and the other colonists were moved to Dantooine. When Admiral Daala destroyed the newly formed colony, he, his wife, and the other evacuees perished. His demise, among many others, contributed to Gantoris succumbing to the dark side and ultimately dying.
