The Imperial Campaigns was the name given to the military incursions made by the Malazan Empire between the 1158th and 1194th years of Burn's Sleep. They were detailed and analysed in a series of volumes also entitled Imperial Campaigns written by Imrygyn Tallobant, who was born in the 1151st year of Burn's Sleep.
...In the eighth year the Free Cities of Genabackis established contracts with a number of mercenary armies to oppose the Imperiums advance; prominent among these were the Crimson Guard, under the command of Prince K'azz D'Avore (see Volumes III & V); and the Tiste Andii regiments of Moon's Spawn, under the command of Caladan Brood and others.
The forces of the Malazan Empire, commanded by High Fist Dujek Onearm consisted in that year of the 2nd, 5th and 6th Armies, as well as legions of Moranth.
In retrospect two observations can be made. The first is that the Moranth alliance of 1156 marked a fundamental change in the science of warfare for the Malazan Imperium, which would prove efficacious in the short term. The second observation worth noting is that the involvement of the sorcerous Tiste Andii of Moon's Spawn represented the beginning of the continent's Sorcery Enfilade, with devestating consequences.
In the Year of Burn's Sleep 1163, the Siege of Pale ended with a now legendary sorcerous conflagation…

Imperial Campaigns (The Pannion War) 1194-1195
Five mages, an Adjunct, countless Imperial Demons, and the debacle that was Darujhistan, all served to publicly justify the outlawry proclaimed by the Empress on Dujek Onearm and his battered legions. That this freed Onearm and his Host to launch a new campaign, this time as an independent military force, to fashion his own unholy alliances which were destined to result in a continuation of the dreadful Sorcery Enfilade on Genabackis, is, one might argue, incidental. Granted, the countless victims of that devastating time might, should Hood grant them the privilege, voice an entirely different opinion. Perhaps the most poetic detail of what would come to be called the Pannion Wars was in fact a precursor to the entire campaign: the casual, indifferent destruction of a lone, stone bridge, by the Jaghut Tyrant on his ill-fated march to Darujhistan . . .
