Nidhogg
Mythological Narrative
A dragon that gnaws at the roots of Yggdrasil, the World Tree. It feeds on the corpses of the dishonorable dead and represents destruction and decay in the cosmic order.
Scholarly Commentary & Evolution
## Gnawer at the Root
Nidhogg is the dragon under Yggdrasil who chews the tree's root and, in Voluspa, flies up from Nidafjoll bearing corpses at the end of the world. Snorri parks him at Nastrond among oath-breakers. He is decay with a name, not a hoard-dragon of the Sigurd type.
The squirrel Ratatoskr carries insults between Nidhogg and the eagle above — a postal service of spite.
## Under the tree
The Eddic poem *Grímnismál* lists Níðhöggr among the serpents gnawing Yggdrasil's roots and names Ratatoskr as the squirrel who runs up and down the trunk carrying the words of the eagle above to the dragon below. In the last stanza of *Völuspá* the seeress sees the dark dragon flying up, bearing corpses in its feathers, even as the new world rises; readers still debate whether its appearance marks a lingering threat or the dragon's own end.
