I totally doubt that Vadderung is mortal.
You and Quantus both, but repeated WOj's say otherwise
Quote:"He's already Kringle when Kringles around...When he's acting in his role of Kringle he takes on the Kringle Aspect when he's doing that he's got all the power of a major lord of Faerie but he's also beholden to Mab while it's going on, Mab's no dummy though so she knows not to order him around. But they do talk and have strategy sessions and stuff like that. The Kringle is what Odin does to keep from dying of old age."
Quote: "If you’re (a powerful immortal being) in the real world, well, the problem is that you’re in the world, and you’re kind of mortal, and something could come along and try and whack you, if they’re fast enough, or good enough, or lucky enough. Which makes Odin a kind of special guy, because he doesn’t mind it, he thinks it’s awesome."

Already brought this up, and of course there is the legends of St Nicholas taming a Dragon.
Basically these two have been at it a long time, and it is likely they are most Dragons and Dragon Slayers in history anf myth. Wikipedia has a list of Dragon Slayers, several of which shout Vadderung. Basically everyone except Bard and Smaug.
It's one of the things about Immortals even if you're mortal enemies your frenemies if onyl for the fact that there are relatively few of you left, the ones that are have been around and you've known for centuries. Love/Hate Frenemies that you know evantually you might have to kill. Otherwise known as Family.
