Auwry was one of the Crinfrid Reavers mercenaries trained by Boholt to slay dragons and draconids. As with every man in his group, he was equipped with a double bit axe and a large crossbow.
In 1275, he, Jamor and two other Reavers ventured to Toussaint where they were hired by the rich guild to kill Iocaste, a Silver Basilisk that was attacking passing caravans and killing merchants. While they were preparing for a showdown with the beast, Geralt appeared. After solving the matter they gave a share of the coin to Geralt and left.
