"There's an ancestral vendetta and blood feud between the Sweers and the Varnhagens."
- - Skomlik , Time of Contempt
The Sweers family were a Nilfgaardian noble house and ancestral enemies of Varnhagens of Sarda. This age-old vendetta was settled, presumably finally for both sides, when a knight of each clan faced off against one another en route between the Korath desert and Glyswen. Neither Sweers or the "Blue Knight" lived to see the final outcome of their duel.
