is proud of his daughter for succeeding where he could not, namely bringing order to Korugar as a member of the Green Lantern Corps. He then tells her that they must work together to stop the Blackest Night. After leaving Korugar, Sinestro travels to visit the grave of Abin Sur and makes plans to lead an assault on the homeworld of the Star Sapphires. Blackest Night When he arrives, he first encounters Carol Ferris. While Sinestro holds no ill will towards Carol and only wishes to free his Corpswomen from Zamaron, he warns Carol that he will hurt her if she stands in his way. Carol then encases Sinestro in a crystal structure, forcing him to relive the death of his love, Arin Sur (Abin Sur's sister).

Afterward, Hal and Sinestro debate whether to contact the Blue or Red Lanterns, respectively. Hal then makes the decision himself. Sinestro relents, tells his Corps that there is a temporary truce with the GLC, and travels with the others to Odym. After gathering the other Corps leaders, Sinestro and the others follow the Black Lantern battery to Earth, where Nekron has already risen. Under Indigo-1's direction, they combine their lights, thinking it
