Lyssa Drak

Lyssa Drak is a member of the Sinestro Corps and the keeper of the Book of Parallax, which is chained to her wrist. She maintains the horror stories and exploits of the members of the Sinestro Corps while also overseeing the final trails of corp recruits through the Fear Lodge, helping them to control their fears and turn them against others.

Aside from recording the history of the Sinestro Corps, Lyssa Drak also seems to have some insight as to what will take place for her corps as well as hinting at an ability to sense the feelings of others. She has a tendency to answer questions with tales from the Book of Parallax.

Background
Hailing from Talok IV, the enigmatic Lyssa Drak was recruited presumably by Sinestro himself to be the Sinestro Corps' historian; acting as the keeper, reader and writer of the Book of Parallax. This tome, which holds the stories of the greatest Sinestro Corpsmen, was chained to Lyssa Drak with yellow energy from Sinestro himself. Lyssa Drak loyaly updates the book and keeps it safe.

When the Sinestro Corps waged war on the Green Lantern Corps, Green Lanterns John Stewart and Guy Gardner were captured and Lyssa was charged with overseeing their captivity. Following the defeat of the Sinestro Corps, Drak was eventually defeated by Hal Jordan) and she and the book were placed under Green Lantern custody.

Lyssa Drak is currently being held in a sciencell on Oa while she awaits trial. A number of Green Lanterns have tried to interrogate her to no avail. To their frustration, she invariably responds with stories about her fellow Sinestro Corps members.
