The part of Aedirn that lies between the Pontar and Dyphne rivers is called Lormark or Upper Aedirn, depending on the interested party's political persuasion. These lands have been disputed for ages, with Kaedwen laying claim to them as well. During the last war with Nilfgaard, Aedirn found itself in deep trouble, fighting an uneven battle to repel the onslaught of the Black Ones in the south. Sensing that its southern neighbor would ultimately bow to the invaders, Kaedwen, Aedirn's ostensible ally in that conflict, sent its armies into Lormark, annexing the region. Several days later Margrave Mansfeld of Ard Carraigh and Marshal Menno Coehoorn, commander-in-chief of the Nilfgaardian army, greeted each other on a bridge spanning the Dyphne River. They shook hands over the bleeding, tortured corpse of the Kingdom of Aedirn, sealing a criminal partitioning of plundered lands. And even though Kaedwen restored Lormark to Aedirn after the war, its taking of the territory with Nilfgaardian support was one of the most disgraceful acts in history.
