Valkur is the protector of all who sail on the sea, and constantly strives to safeguard his worshipers against the whims of Umberlee and Talos, who are his sworn enemies. He is a god who relishes shipboard life and the thrill of exploration. He exhorts his followers to live life with vigor and to strive against anything the Gods of Fury may throw against them.

Valkur is the patron of sailors both mercantile and naval, as well as the god of favorable winds and storms. He appears as a jolly sea captain who can pilot any vessel. Changeable as the winds, the Captain of the Waves is a fiercely loyal leader. His worship is conducted on the decks of ships, and many of his clerics serve at sea. His symbol is a shield with a cloud and three lightning bolts.
