Originally a part of Brokilon, Owl Hills were taken by Bruggian forces in the 12th century and the local primeval forests were cut. Dryads did not recognized the annexation and continued to attack human colonizers; these attacks were still remembered in the 1250s.
By the 1260s forests grew here again. While Bruggians remained de jure owners of the Hills, Brokilonians such as Milva knew most of the hidden paths and were able to sneak through the region without great effort.
7th August 1267 Nilfgaardian Army stormed the region, burning villages and forests. Geralt, Dandelion and Milva, who intended to travel south towards the Yaruga, were forced to change direction east after witnessing a fierce battle of the local village.
