In this timeline of Norse Mythology, the Great Ragnarok, the end times of war and destruction never occurred due to a multitude of reasons. One of these changes is Fenrir being treated as an equal ally of the Aesir Gods rather than a ticking timebomb for their demise. Fenrir, who was once prophesied to be the leading killer of the gods, became their trusted ally through companionship. He has been trusted to guard Yggdrasil, the Tree of the 9 realms, along with Nidhogg, Snake of Yggdrasil.
