Níðhgr

Níðhöggr is a dragon or serpent in Norse mythology that gnaws at the roots of Yggdrasil, the world tree. The name Níðhöggr is Old Norse and can be translated as "malice biter" or "corpse-worm." Its existence is primarily described in the Poetic Edda, particularly in the poem Grímnismál and the Vafþrúðnismál. In these texts, Níðhöggr is depicted as a malevolent entity residing in Niflheim, one of the realms connected to Yggdrasil's roots. It is said to feast on the corpses of the dead at its dwelling place. The constant gnawing of Níðhöggr at Yggdrasil's roots represents a destructive force in the cosmos, contributing to the overall instability of the world. Despite its destructive role, Níðhöggr is also sometimes mentioned in conjunction with other creatures like the squirrel Ratatoskr, who is said to carry insults between Níðhöggr and the eagle that dwells at the top of Yggdrasil. This interaction suggests a cosmic balance, even amidst destruction. Níðhöggr's presence is often linked to the concept of Ragnarök, the prophesied end of the world, where it is said to continue its gnawing until the very foundations of existence are threatened.
