Sildar Hallwinter

Sildar Hallwinter is Gundren Rockseeker's human bodyguard. Secretly he is also a member of the Griffin Cavalry, a branch of the Lord's Alliance, an organization dedicated to the protection and advancement of Faerun. He was hired by Gundren to escort him to Phandalin. Gundren supposedly had found the lost Wave Echo Cave said to poses incredible treasures. As a secret member of the Lord's Alliance, Sildar took the job in order to find Wave Echo Cave and revitalize the once prosperous town of Phandalin. Gundren paid Sildar half at the beginning of the journey and was to pay him the other have once they reached Phandalin. Sildar was supposed to meet with his fellow Lord's Alliance member Iarno Albrek in Phandalin.

While on the Triboar Trail Gundren and Sildar were ambushed by goblins and taken to a cave overrun with goblins working in the service of Klarg the Bugbear.
