Knight Terrors: Green Lantern (2023) #1

Back in space to face his greatest fear!

Something is wrong in Sector 2814, and Hal Jordan, Kilowog, and a few other Lanterns must find the mysterious disturbance, despite a ban on any of Earth's Green Lanterns leaving their world.

What they discover is a planet controlled by a familiar face--the face of Hal's greatest fear!

And in a backup story, Sinestro finds himself thrust into a new reality that drags him into the darkest corners of his past...and perhaps his future.
