This realm is bordered by Kaedwen to the north, Redania to the northwest, Temeria and the massif of the Mahakam Mountains to the west, and Lyria to the south. The Blue Mountains line its eastern frontier. Aedirn's coat of arms is a golden-red chevron on a black field, and its capital is Vengerberg. Not long ago the country nearly disappeared when Nilfgaard occupied its southern territories and its northern neighbor and supposed ally, Kaedwen, treacherously annexed Upper Aedirn. Though the invaders were defeated and Kaedwen withdrew from Aedirn's northern lands, the kingdom's fate still hangs by a thread. The country has been ravaged by peasant revolts and its central government seems ever unsteady.
