Mos Entha, a settlement located on the desert planet of Tatooine, was constructed opposite the Mospic High Range. During the reign of the Galactic Empire, Jabba Desilijic Tiure, the Hutt crime lord, maintained slave holding areas within Mos Entha. Eventually, Jarm Brock, an operative of Crimson Dawn, successfully infiltrated and disrupted Jabba's activities in the town. Jabba responded by dispatching teams to kill Brock and his associates, but these attempts proved unsuccessful. Consequently, the Hutt employed Deva Lompop, an information broker, to collaborate with Boba Fett, the bounty hunter, to accomplish the task.
The initial mention of Mos Entha occurred in the Star Wars Legends reference book, Inside the Worlds of Star Wars: Episode I, authored by Kristin Lund and published on October 1, 2001. Subsequently, the settlement entered canon when components from Inside the Worlds of Star Wars: Episode I were republished within the reference book Star Wars: Complete Locations on September 27, 2016.
