The war took place near the city of Kialune, near the fortress Overlook. The members of the Black Company left battled Soulcatcher after she returned from the Plain. The Company hid in Overlook for several years, mounting assaults on Soulcatcher and her newly created forces. Soulcatcher eventually devoted her entire attention to obliterating Overlook and the Company forces inside, a task which took months. The Company suffered several defections during this time, which led them to a weakened state in which they could no longer continue the war. Soulcatcher emerged from the war as the undisputed ruler of Taglios and the Shadowlands.
The war is only mentioned in retrospect in the books.
