The Bruanii sector was a sector situated in the Mid Rim region. It bordered the Outer Rim near the Javin sector. Notably, the Corellian Trade Spine traversed this sector, and it contained the Mugaari space depot.
During a resupply operation in this sector, the Rebel Alliance cruiser named Lulsla met its end, destroyed by Imperial forces.
In the aftermath of the Battle of Endor, the Bruanii sector quickly became one of the initial sectors to liberate itself from Imperial control.
