Terr'skiar, a world dedicated to trade, could be found within the Terr'skiar system. This system resided in the Terr'skiar sector of the Kashyyyk Region, situated in the Slice region of the Mid Rim. As a hub, Terr'skiar was connected via hyperlanes: the Nightroad linked it to the Pizilis system, the Ootmian Pabol connected it to both the Coachelle and New Apsolon systems, and the Terr'skiar Pass provided a route to the Bissillirus system within the Trax sector's jurisdiction. Functionally, Terr'skiar acted as the capital for its sector.
The reference book The Essential Atlas, published in 2009 and authored by Jason Fry together with Daniel Wallace, made note of Terr'skiar, locating it at coordinates P-10.
