Dol Angra is a valley and a valuable trade route for Lyria and Rivia, Aedirn, Dol Blathanna and Kaedwen with the south. The trade route crosses the Yaruga river roughly mid-course, where it is at its most shallow and continues north to the Pontar and Temeria.
Second Northern War
In 1267, the valley was armed by Aedirnian and Lyrian soldiers preparing to set off the Second Northern War with the taking of Glevitzingen, under Imperial disguises. After the Thanedd coup and the capture of Glevitzingen, the valley witnessed many skirmishes including the first and second battle of Aldersberg.
