Sentinel

Engineer Alan Scott was surprised to find himself the only survivor of a train wreck, but soon learned the answer laid in the green train lantern he was grasping. The lantern, it turns out, was illuminated by a special meteorite from centuries ago and that, with Alan, it would bestow upon him great power. Scott fashioned a ring that held the lantern’s power for twenty-four hours, allowing him to do anything his mind willed him to do. As the Green Lantern, Alan became a founding member of the Justice Society of America; he later learned his lantern was powered by the Starheart, a magical entity the Guardians of the Universe had imprisoned in that fateful meteorite.
