Hræzlyr

Guardian dragon of the Mythril Mountains in Nidavellir, 
He keeps the dwarfs away in the hopes that when Ragnarok occurs he can use the power of the Mythril ore to protect his realm. Sadly all of this came to an end when the party slain him allowing the dwarfs to use the Mythril ore to create new weapons. After his death the council of dragons vowed alliance to Hel and her cause to slay the gods and their followers.
