Nidhogg - The Corpse Eater.
Dwelling between the roots of the World Tree, this strange creature spends his time attacking the bark and draining the sap of Yggdrasil, devouring Oathbreakers' corpses in the snake walled-fortress of Naströnd and waiting for the end of time—when he will carry the dead on his wings.
But, of course, the end of time has arrived, and Nidhögg intends to enjoy himself as the worlds collapse.
