Green Lantern #23.4: Sinestro
The Book of Parallax holds the entire history of Sinestro and his Corps. When the Green Lanterns, led by none other than Hal Jordan, came to Sinestro’s home planet of Korugar, they plunged it into chaos. They cursed Sinestro’s name and, ultimately, brought about the destruction of the entire planet. But what became of Sinestro? One never-before-seen moment from those dark days holds the key to his future.
