Violet Lantern Corps

Carol Ferris reveals to Hal Jordan that during the most recent time the gem possessed her, she gained knowledge of the Star Sapphire: they come from Sector 1416 and comprise a Star Sapphire Corps whose purpose is to spread love throughout all 3600 sectors of the universe. The leaders of the Corps are Oans who, after migrating to Zamaron, found a parasitic crystal which they shaped into several Star Sapphires. These were used to empower females who had been loved and spurned, providing them the opportunity for revenge.
