The Varnhagens was a Nilfgaardian clan who established the fortress at Sarda in Geso. Remiz was once employed by them. They were sworn enemies of the Sweers family. As it happens, this age-old vendetta was settled (quite finally for both sides), when the knights faced off against one another en route between the Korath desert and Glyswen. Neither of them lived to see the final outcome of their duel.
