The Faekin did not know when the Primordial Beast Nidhogg managed to awaken because its movements were not noticed even by the Great Mother Tree. In fact, Alfheim experienced such a frightening tremor when the Primordial Beast Nidhogg attacked the Great Mother Tree for the first time in a long time. Even the Great Mother Tree was unable to defend herself as she lost a tenth of her elemental power with that sneak attack.
The Great Mother Tree only exercised most of its power at that time to force the Primordial Beast Nidhogg into a state of sleep. The only problem is that the Great Mother Tree cannot force the Primordial Beast Nidhogg to sleep again for a long time. The Primordial Beast Nidhogg awakened after a few days but the Great Mother Tree managed to prepare this time.
