The Form of the Devourer

Scene from the Niflheim video — the roots of Yggdrasil, exposed to time and rot.
This scenery, visually depicted as the twilight of realms, represents the grip of the past; where Nidhogg devours the roots of life.

"Disclosure of the enemy - the form of the devourer.
There he is. Níðhöggr. Not just myth, not just metaphor — the ancient hunger given form."
