Nidhoggr

Nidhoggr is a demon in the series.

History
Nidhoggr (literally meaning Malice Striker in Old Norse), also spelled as Nidhogg, in Norse mythology is a dragon serpent that gnaws at the roots of the World Tree, Yggdrasil. He lives beneath the roots of Yggdrasil and gnaws at them as they are the only thing that keeps it from the world.

The squirrel Ratatoskr brings words of envy between Nidhoggr and the eagle Hresvelgr. The only person capable of controlling him is the goddess Hel. Its existence is the portend of the Ragnarok that signals the end of all.
