Biography
The woman who would become known as Scar was a member of the Oan race, who were descended from the Maltusians. She was one of the few female members of this race to become one of the Guardians of the Universe. For thousands of years, this previously unnamed Guardian silently administered the affairs of the Green Lantern Corps along with her brethren.

This being took an active role during the Sinestro Corps War and was disfigured by the Anti-Monitor. The Anti-Monitor's corruptive influence stained not only her body, but her soul as well. Taking the name Scar, she retreated into the bowels of the planet Oa, where she became the caretaker of the Book of the Black - an ancient tome foretelling the coming of the "Blackest Night".
