When the Green Lantern Quarzz Teranh gave his life to close a black hole, Ghr'll and his partner Xylpth found the brave Lantern lying on an asteroid and near death. The two Lanterns offered to take their friend to Oa hoping to save his life, but Quarzz refused, instead choosing to live out his last moments gazing at the wonders of the universe he had protected for so long. Ghr'll and his partner Xylpth patrol Sector 151, a Sector once home to a vast network of worlds that were destroyed in a war against Mongul. Now, in this Sector composed almost entirely of asteroids, Ghr'll and Xylpth search for any signs of life they might yet protect.
