Z-LOQ existed as a planetary base on an asteroid. During the period from 2 BBY to 4 ABY, the rebel agent Alexsandr Kallus, accompanied by the protocol droid known as Dee-Four, encountered Grand-engineer Lony Coleema while on Z-LOQ. Following the conclusion of their meeting, Coleema was abducted by the IG-88 assassin droid designated IG-88B.
The short story titled "A Rebel Bounty," featured Z-LOQ; this story was contained within the Star Wars Adventures Annual 2020 comic book. Nick Brokenshire both wrote and drew the story, which was then released by IDW Publishing on November 18, 2020.
