Hal Jordan's enemies: Lyssa Drak
Lyssa Drak is also involved in the training of prospective Sinestro soldiers. Once a corpsmen has finished the physical training and was judged by Arkillo, the Sinestro Drill Sargeant, the new recruit would have their yellow power ring drained of energy and they would enter a Fear Lodge. Within the dark confines of the Fear Lodge, the recruit would have to face their fears and embrace them in order to recharge their ring. If a recruit succeeded, then their ring would open the Fear Lodge. If the recruit failed, then they would be left to die within either from thirst, starvation, suffocation, or suicide. Whatever the recruit's fate, Lyssa Drak was there to record their success or failure in the Book of Parallax.
Lyssa Drak presided over Amon Sur's initiation and helped prepare him for his time in the Fear Lodge. Amon had approached Lyssa for help to purge his fear. Instead, Lyssa read from the Book of Parallax stories of other Sinestro Corps members including Bedovian, Despotellis, Low, Karu-Sil, and Kiriazis. Afterwards, Amon entered the Fear Lodge, learned his greatest fear is the Green Lantern Hal Jordan, and succesfully ignited the charge in his ring.
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. Whether this is actual knowledge of the future or simply plans intended by Sinestro remain to be seen.
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. Hal Jordan, along with fellow Lanterns Graf Toren and Tomar Tu, came to the rescue. Lyssa Drak was grateful for the chance to defeat the three Lanterns, for she wanted to add her own success to the pages of the Book of Parallax. Unfortunately, Drak was defeated herself and she and the Book were placed under Green Lantern custody.
As she was being transported to Oa to be placed in a Sciencell, Lyssa told the story of fellow Sinestro soldier Kryb, an evil creature known for attacking coupled Green Lanterns and abducting their newborn children.
Several members of the Green Lantern Corps have tried to interrogate her following her capture, but she inevitably tells them a story about her fellow Sinestro Corps members rather than share her secrets. She was awaiting trial on Oa when Scar, the Black Guardian, released Red Lantern Corps member Vice in the Sciencells to provoke a massive riot. In the melee, Drak stole away to search for the valuable Book of Parallax, only to find the dreaded Book of the Black. Shortly after this, Scar surprised her from behind and has somehow trapped her within the pages of the Black Book.
She was released from her prison by Krona, who wanted her to be the Keeper of a new Book that he intended to be created.
