Darpa sector (aka, Ralltiir sector) was in the Ringali Shell in the Core Worlds, along the Perlemian Trade Route. Planets in the sector included Esseles, Ralltiir and Rhinnal. It once contained the Esselian Empire.
Rebel Alliance operatives in this sector were listed in datapacks recovered from the base on Dankayo. These lists were discovered by a young technician aboard Elusive, an Imperial transport ship en route from Dankayo to Tolan. The Dankayo Rebels reportedly supervised intelligence operations in three sectors. Thus Ralltiir was presumably one of the three.
