Weylin was a Tortallan soldier who fought in the Scanran War. He was stationed at Haven under Sergeant Connac as the sergeant's scout. He avoided a grisly death when the Scanrans attacked Haven en masse in early June of 460 HE, as he and the rest of Connac's squad accompanied Keladry of Mindelan and Nealan of Queenscove to Fort Mastiff so they could report to Lord Wyldon.
When Kel deserted in order to find her refugees, Connac and his men went after her, as did many others. Weylin surveyed the slavetakers' camp in order to help Kel make the best plan of rescue.
