Sercy was a religious figure of her home world, located in space sector 4, who was recruited by Brother Hymn and taken to Odym to be instructed by Ganthet and Sayd. Her homeworld had long been oppressed by Evil Star, an old foe of Green Lantern Hal Jordan, and she was eager to use the blue light to stop him. During her induction, however, Agent Orange, the wielder of the orange light of avarice, sent his Orange Lantern Corps upon Odym to seize a Blue Lantern Power Ring for himself.
