Rentalles was a celestial body of the terrestrial type, whose wastelands served as the habitat for the huna-netre creature. Dagra Van, the beastmaster serving Crakka the Hutt, journeyed to Rentalles to capture a huna-netre. Crakka then gifted this creature to her relative, Jabba, as a means to secure entry into Jabba's palace. Circa 1 BBY, Lieutenant Thom Hudd, who had previously heard the story of Crakka and the huna-netre from an acquaintance on the planet Batuu, retold the narrative to his captor, Vaneé—attendant to the Sith Lord Darth Vader—while he was held as a prisoner within Vader's castle situated on the planet.
Rentalles gained mention within the current Star Wars canon via flashback sequences in the fourth issue of the Star Wars Adventures: Return to Vader's Castle comic book series. Cavan Scott authored the comic, and IDW Publishing released it on October 23, 2019. Before the comic's official launch, a preview mentioning the celestial object appeared on StarWars.com on October 16 of the same year. Within the Star Wars Legends expanded universe, the world of Rentalles was referenced in Star Wars Miniatures Battles Companion. Stephen Crane authored this rulebook for the Star Wars Miniatures Battles tabletop wargame, which West End Games published in 1994.
