I had considered to start the story for simplicity only after Hagen's theft of the gold, so Fafnir, Sigurd and Brunhilde would all be already dead. But actually it does limit the choice of legendary characters, so go ahead everybody! If I may make a suggestion, I see more Gullveig as Gudrun and Ana as Brunhilde. :D

Gullveig, have you tried to turn your avatar into a GIF? It's the only working method I know to keep the colours even when the icon gets shrunk.
