Dragons:
Most of the Dragon's abilities in this Mythos will conform to those of D & D. There are only three types present, White, Red and Green. Some dragons of note are:
Fafnir: This dragon was slain by Sigurd. When its blood is consumed it bestows the person with the ability to understand all types of bird languages. It guards a hoard of a double H treasure.
Nidhug: This dragon dwells below the tree Ygdrasil where it gnaws relentlessly at its roots.
Ofnir: This dragon helps Nidhug in his duties.
So, it looks like we can pretty much stat him up from scratch.
