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). The wars areonly mentioned in retrospect in the Annals and take place in the 15-year gap between She Is The Darkness and Water Sleeps.
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. A final crushing blow came when the Bahrata Battalion was betrayed by the defector Khusavir Pete and was wiped out by Protectorate forces at Kushkhoshi. During this bloodbath, about 500 people (consisting primarily of their "largest surviving force of allies" but also containing many Company brothers) were lost. This marked the defeat of the Company and an end to the Kiaulune wars. 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 former Shadowlands.
