Hagen

Well it is a rather interessting character from one of the few real old mytholgies of Germany. Ask me about him and I shall go on for ages...

Perhaps an exerpt from the Wikipedia will serve better: " In the Nibelungenlied he is called Hagen of Tronje (perhaps Drongen in Ghent). In German tradition Hagen is especially grim, implicable, and violent and in two accounts one-eyed. According to the Thidreks saga, Hagen was not fully human, being fathered by an elf on the king's wife. In these accounts it is Hagen who kills the hero Siegfried during a hunt, wounding him on the only part of his body which was not indestructible.
In German accounts Gunther and Hagen are the last survivors of the fall of the Nibelungs. Hagen refuses to reveal the hiding place of the Nibelung treasure as long as his king Gunther lives. When Gunther is slain, the mortally-wounded Hagen continues his refusal with sure knowledge that Gunther cannot now weaken and betray the secret."
