Green Lantern

The Corps was in the process of recruiting 7,200 new members in an effort to rebuild their ranks following their destruction at the hands of the villain Parallax. The rings allowed their bearers to conjure virtually any object or form of energy limited only by the imagination and willpower of the wearer, and thus the rings, which all include a sentient computer and the means to travel through interstellar space, sought out beings capable of overcoming great fear. When Sarn put his on, he tried to use it to use it to continue fighting the Thanagarians, but as the Corps code does not provide for participation in planetary wars, it immediately transported Sarn to the planet Oa, home to the extraterrestrial Guardians of the Universe, who administrated and oversaw the Corps. There, he would be trained as a Green Lantern under the supervision of Kilowog.
