Lynos IV was a planet-like body in space. Han Solo and Chewbacca, who were smugglers, were once involved in a situation on Lynos IV that concerned Zefin Tuzo, who was the manager of a resort located on the space object Marquinn. Because of this situation, Tuzo developed a strong dislike for them and subsequently collaborated with the gangster Vullen Candroon to lure them into an ambush sometime in the period between 10 BBY and 0 BBY.
The comic story "Chewie's Day Off" featured Lynos IV; John Barber wrote the story, and IDW Publishing released it in the fourteenth issue of the 2017 Star Wars Adventures comic book series on September 26, 2018.
