The Lesser Plooriod Cluster, a star cluster, encompassed the Urce sector and shared a designation similar to the Plooriod Cluster. During the Republic Era, a hyperspace route traversing the Urce sector was mapped. This route was utilized by Ithorians originating from the planet Ithor, and was subsequently charted by the Trade Federation.
During 28 BBY, the Ithorians endeavored to publicly release the map detailing this hyperspace route. This was proposed in a motion presented before the Senate of the Galactic Republic. Supreme Chancellor Palpatine initiated a debate on the Senate floor, providing an opportunity for a human senator and a Trade Federation delegate to present counter-arguments against the Ithorian senator who introduced the initiative. Senator Padmé Amidala cast her vote in support of the motion, reflecting on the fact that the inhabitants of the Urce sector only possessed a claim to a portion of the route, while the Ithorians had been utilizing it for a considerable period before the Trade Federation's mapping efforts. Despite this, the motion was ultimately unsuccessful.
Within established canon, the Lesser Plooriod Cluster is referenced in Queen's Shadow, a young-adult novel from 2019 authored by E. K. Johnston. In the Star Wars Legends continuity, the Lesser Plooriod Cluster was first mentioned in the 1980 novel Han Solo and the Lost Legacy, penned by Brian Daley. This novel served as the third book in the Star Wars: The Han Solo Adventures trilogy. The cluster then made its first complete appearance in Star Wars: X-Wing Tour of Duty: Imperial Pursuit, an expansion for the Star Wars: X-Wing video game released in June of 1993, following the game's initial release in February of the same year.
