The Dolomar sector, a sector situated in the Core Worlds, contained several planets. Among these were Balfron, Caprioril, Dolomar, Kamparas, Pantolomin, Phorliss, and Wor Tandell.
The New Republic moved the sector's capital from the planet Dolomar to Caprioril.
Grand Admiral Thrawn's offensives heavily targeted both the Dolomar sector and the Farrfin sector. The New Republic mounted strong defenses in these sectors, with Admiral Gial Ackbar himself inspecting the defensive arrangements.
