Grüne Leuchte #11/1980

In "Sinestros Geheimnis!", Hal Jordan, isolated from Green Arrow, follows Sinestro to his homeworld, where he meets the enigmatic Hal Katma Tui. She guides him toward the mysterious Null Chamber, a place tied to Sinestro’s past, but the fallen Green Lantern has set a deadly trap. With help from Katma Tui, Hal narrowly escapes—but Sinestro slips away, leaving more questions than answers. Written by Denny O'Neil and illustrated by Joe Staton, with inks by Frank McLaughlin and colors by Adrienne Roy, the cover by Dick Giordano captures the tension of this pivotal journey.
