Urce, an astronomical body, could be found within both the Mid Rim and the New Territories. Its location was also identified as grid square L-6 on the Standard Galactic Grid. This celestial object lent its name to the Urce sector.
The initial mention of Urce in current Star Wars canon occurred on a galactic chart featured in Star Wars: The Force Awakens Beginner Game. This boxed set, a 2016 release from Fantasy Flight Games' Star Wars Roleplaying line, included the reference. The planet named Urce had previously appeared in the Star Wars Legends continuity, specifically in Alliance Intelligence Reports, a 1995 sourcebook published by West End Games for their Star Wars: The Roleplaying Game.
