The name Favner (Icelandic Fáfnir) originates from the Norse/Nordic mythology, and more specifically from the Sigurd saga. Favner is a mythical creature in the form of a dragon, but of human descent. Favner is the fierce guardian of an enormous golden treasure.
The story of Sigurd is common for Scandinavian and ancient Germanic traditions and has been used as source material for e.g. Richard Wagner in his monumental opera cycle Das Nibelungenlied.
Beautiful illustrations of the very dramatic saga are the magnificent rock carvings Gökstenen and Sigurdristningen in Södermanland (Sweden), both dating back a millennium.
