"Nidhogg: The Dark Dragon and the End of the World"
Traditionally also spelled Níðhǫggr, often anglicized Nidhogg, meaning Malice Striker, a dragon/serpent that dwells in the roots of Yggdrasil, the World Tree. Níðhöggr, always gnawing at the roots sits in between Niflheimr, the land of the dead, and Midgard, the Land of Men.
Níðhöggr is often brought news and insults by Ratatoskr, the squirrel the lives on Yggdrasil, often resulting in rousing the serpent in irritation against the Eagle, whom lives at the top of Yggdrasil
Níðhöggr is mentioned in the Völuspá, where he is identified as a dragon or serpent, and speaks of his coming during or before Ragnarok.
"There comes the shadowy
dragon flying,
glittering serpent, up
from Dark of the Moon Hills.
He carries in his pinions
—he flies over the field—
Malice Striker, corpses.
Now will she sink."
Nidhogg is a dragon in Norse mythology that lives at the roots of the world tree Yggdrasil, gnawing at its roots. According to legend, Nidhogg's eventual success in destroying Yggdrasil is seen as a harbinger of the end of the world, Ragnarok. Nidhogg is a dark and ominous creature that represents the forces of destruction and chaos that threaten the world.
Nidhogg's symbolism is closely tied to themes of decay, destruction, and renewal. As a creature that feeds on the roots of the world tree, it embodies the destructive power of time and entropy, as well as the transformative power of death and rebirth. In this way, Nidhogg serves as a reminder of the cyclical nature of existence, and the need to accept both the light and dark aspects of life.
In Norse mythology, Nidhogg is also closely associated with the dead, as it is said to feast on the corpses of those who have died. This further emphasizes the creature's role as a symbol of death and renewal, and reinforces the idea that even in death, there is the potential for new life and growth."
