One of the biggest Green Lantern questions that HBO's Lanterns is set to answer has nothing to do with its central murder mystery. Instead, it's tackling a piece of DC lore that comic fans have debated for years: Why does Earth have so many Green Lanterns? That means Space Sector 2814 currently has three active Green Lanterns, even though the Guardians of the Universe traditionally assign only two Lanterns to each of the universe's 3,600 sectors. Earth has become one of the Green Lantern Corps' richest recruiting grounds because it consistently produces an incredible number of fearless individuals. The very first Green Lantern was Alan Scott, although his powers came from a mystical source rather than the Green Lantern Corps' power battery.
