Níðhöggr
Nithhogg in Bellows; Nidhug in Anderson
The dragon beneath Yggdrasil: a destructive presence at the world-tree’s roots, linked with the dead and named in several Eddic passages.
Quick answer
Níðhöggr is a dragon or serpent in Old Norse mythology. Eddic sources place it beneath Yggdrasil, where it gnaws from below; other passages associate it with the bodies of the dead and show it flying at the close of Völuspá.

What the source books say
In Grímnismál, Ratatosk carries the eagle’s words down to Nithhogg, and Yggdrasil suffers because a hart bites above, its trunk decays, and Nithhogg gnaws beneath. Völuspá associates Nithhogg with the blood of the slain and closes with the dark dragon flying from below while bearing bodies on its wings.[1]
The Prose Edda places a root of Yggdrasil over Hvergelmir in Niflheim, where Nidhug gnaws it from below. It also expands the world-tree scene: Ratatosk carries hostile words between Nidhug and the eagle, and innumerable serpents share the region beneath the ash.[2]
Dragon identity and appearance
Bellows’s final stanza of Völuspá explicitly calls Nithhogg both a dragon and a serpent and gives it wings. The passages about the roots focus instead on position and action, not anatomy. The sources do not specify colour, size, number of limbs, or a single fixed form.[1]
- Named individually among a larger population of serpents
- Placed at the lowest part of the world-tree’s vertical structure
- Connected to both physical decay and punishment of the dead
- Described as flying only in the poem’s final, difficult stanza
Major themes
Destruction beneath renewal
Yggdrasil remains the organising structure of the cosmos while suffering continual damage. Níðhöggr embodies the destructive pressure at its roots rather than a single crisis that can be defeated once.
A connected mythic ecosystem
The dragon is part of a network of animals whose actions span the tree. Ratatosk’s route between eagle and dragon makes hostility itself travel vertically through the cosmos.
Uncertainty at the poem’s ending
Níðhöggr’s flight concludes Völuspá after its vision of destruction and renewal. The stanza supplies a striking last image without explaining what the dragon’s departure means or what follows it.
