"Inside the fortress... guarding the Book of Oa..." At the mention of Scarface's location, Ganthet's face went deathly pale. The Guardians of the Universe rose at once. Ganthet, Alex, and the others shot out of the central council hall, breaking the sound barrier as they flew toward the fortress. The Book of Oa was an enormous book kept in a fortress on Oa Star. Created before the Seven Lantern Corps, it contained much of the history of the Guardians of the Universe and the Green Lantern Corps.
