From Ardrana

Anstuf is a Dwarven fighter from the Thair Mountains. He occasionally serves as a messenger for King Thorin, as one of the few Dwarves that tolerates extended periods above ground. His best friend and assistant is a fellow fighter named Vanso.

Prior to his current position, Anstuf was an adventurer. He, Vanso, and a third Dwarf named Kheeps went on a mission to stop the wizard Bargle from continuing his rampage through the towns of eastern Faxanadu.
