The Bi-Boran Cluster was a stellar grouping, specifically a star cluster, that held within it the system where the planet known as Shadda-Bi-Boran resided, situated within the Outer Rim Territories. The demise of the star called Shadda within the Bi-Boran Cluster was observed by Atour Riten, an event that ultimately led to the cataclysmic destruction of Shadda-Bi-Boran.
Notably, the spelling of the cluster's name in the novel Death Star includes a double "r" ("Bi-Boran"), differing from the spelling of the planet's name, Shadda-Bi-Boran, which uses only a single "r".
