The Ssi-ruuk Star Cluster, alternatively called the Ssi-Ruuvi Cluster, constituted a star cluster located far into the Unknown Regions, encompassing within it the Ssi'kaat system.
Bakura, a planet situated in Wild Space, represented the closest planetary body not governed by the Ssi-ruu; it subsequently became the target of their invasion. Immediately following the commencement of this invasion, Gaeriel Captison dispatched an urgent plea for assistance directed towards both New Republic and Imperial military units.
