Saint Walker

Saint Walker is one of the supporting characters of the Green Lantern series. He was a inhabitant of a planet ravaged by the Red Lantern Corps. He traveled to Mogo—who had promised Walker that if he sought him out, he'd retrieve him from his "blackest night"—and became a hermit, wandering the planet in search for the "saviour". Saint Walker traveled to the mountain tops of Mogo, where he was unveiled that the saviour was himself. He was bestowed with a Blue Lantern Power Ring and battery to accommodate his position as a Blue Lantern. After he had completed his journey, Saint Walker joined the Green Lantern Corps's pursuit in repressing the Red Lantern Corps.
