The Pimbrellan League, situated in the Kathol Outback at the terminus of the Sebiris Run, comprised an alliance of three planets. Decades prior to the Battle of Endor, followers of Pinacism established settlements forming this League. The planets constituting the League included Dolstan, Swedlan, and Bresan. These planets each developed independent nation-states alongside a modest industrial sector focused on manufacturing comlinks, satellites, hover vehicles, and droids. Within Pimbrellan society, education held significant importance, and the Pinacist leadership possessed advanced learning.
To safeguard their constituent worlds from threats posed by pirates and slavers, the League operated a modest fleet of corvettes. In contrast to numerous inhabitants of the Outback, the League monitored happenings in the galaxy through operatives stationed on Gandle Ott. Their Pinacist beliefs dictated a passive role during major historical occurrences, followed by an opportune moment to capitalize on the aftermath. The collection of intelligence was crucial for determining the appropriate timing. With the decline of the Empire, discussions intensified regarding whether this signified "The Event," prompting their re-emergence into galactic affairs to realize their predetermined purpose.
