Bork's Wife appears only in the Movie Short, Book of Dragons, and remains un-named, referred to only as "Bork's Wife" in the credits at the end.
Life With Bork
Book of Dragons details numerous species of dragons and the Viking who first studied them, Bork the Bold. However, appearing along side of him during his interactions with dragons is a Viking woman, known only as Bork's wife. The progression of Bork's study of dragons through his life appears to run parallel to his life with this woman. Though never actually stated, the movie short gives the impression of at first Bork is alone, but then goes through courtship of this unnamed woman. At the end, as Bork writes down all he has learned of dragons, we see this woman tending his various dragon-induced wounds. Bork's wife has stayed with him through thick and thin, despite appearing accident prone.
