The Kiaulune Wars were a series of conflicts between the Black Company (led by Sleepy and Ky Sahra, who were outclassed in terms of sorcery) and the Taglian Protectorate of Soulcatcher (the armies of which were led by Mogaba).
After Soulcatcher trapped the Black Company's leadership (the "Captured") on the Plain of Glittering Stone, she seized control of Taglios and declared herself its Protector. After she was attacked by the remainder of the Black Company, she set out to destroy them. The war took place near the city of Kiaulune, near the fortress Overlook. 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 itself with a specially crafted sorcery, a task which took months. The Company suffered several defections up to that point, which led them to a weakened state in which they could no longer continue the war. Having lost Overlook, the Black Company survivors dispersed into the Taglian underworld. Soulcatcher emerged from the war as the undisputed ruler of Taglios and the Shadowlands.
The war is only mentioned in retrospect in the annals.
