The Clan of Sweers are Nilfgaardian kin, and are eternally fighting with the other clan established in the fortress Sarda called the Varnhagens. As it happens, this age-old vendetta was settled (quite finally for both sides) when a knight of each clan 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.
The horsemen came closer. At their head, on a powerful grey, rode a giant of a man in a glittering blue, enameled suit of armour. Close behind him rode a second armoured horseman, while two more in simple, dun costumes - clearly servants - brought up the rear.
