Tiw
Tiw is a deity worshiped by the Weswarans.
Tiw is called "the warrior"[1].
According to Sefawynn, he once bound the wolf Fenris and was fated to eventually be killed by him. However, when the Black Bear freed Fenris, Fenris consumed the goddess Friag instead, and Tiw escaped his fate[2].
Sefawynn swears by "Tiw's holy name".[1].
Trivia
In the real world's mythology, Tiw is the Old English name of the deity equivalent to the better-known Norse god Tyr. The modern English word Tuesday comes from this name ("Tiw's day").
