ATLI In the Saga of the Volsungs, in Old German mythology, Atli was King of Hunland, but it appears that he was merely the dark power masquerading as a mortal, for he invited his wife, Gudrun's brothers to his court, hoping to seize the golden treasure, the sun light, which the brothers had received from the dead Sigurd. They had already buried these treasures in the Rhine river, and then went on to Hunland, where Atli, as they had expected, killed them both.
