Sister Sercy is the fourth being to be inducted into the Blue Lantern Corps. As is Blue Lantern protocol, Sercy was selected by Brother Hynn to bring hope to her sector of space. Sercy was taken to Odym to be inducted into the corps by Ganthet and Sayd. After finishing her schooling in the ways of the ring, Sercy hoped to return to her home planet to save her people from the oppression of Evil Star. Sercy had just come to Odym with Brother Hynn when Larfleeze and his Orange Lantern Corps attacked Odym, seeking a blue ring of his own.
