|“||May the blessing of Mother Yggdrasil be with you...||”|
Nidhoggr is the devourer of the dead and the most terrible of all dragons. She is ever chewing at the roots of Yggdrasil, the tree of life. She is the mortality of the world and a sign of its coming demise.
On iRO, this character is localized as Nidhoggur.
It is discovered that Frigg's existence is bound to Nidhoggr and the dragon's summoning allowed Frigg to reach out to Chaos and the others after Payon's destruction. In addition, Nidhoggr had also been tasked to guard Yggdrasil, the great tree that binds all realms together.
After Surt was sealed by Thanatos, he managed to relay whispers to Nidhoggr, causing her to become confused and lost in her loneliness. When she at last sealed herself off from everything, Bifrost was torn asunder, its crack engulfed in a Forest of Mist. It wasn't until Loki and a lone adventurer sought her out that Nidhoggr regained herself and realized that she was being manipulated by Surt.
