When little Fenrir was born he scared all of the gods. That’s because he was the wolf son of Loki the Norse God of Chaos or Mischief and his mom was a giantess named Angrboda. A prophesy foretold that a wolf would kill Odin and bring on the Ragnarok -which is the very end of the world.
To prevent the prophesy coming true, the gods tried again and again to chain Fenrir. Each time they failed, Fenrir was too strong. Finally they found the right leash – a magic ribbon called Gleipnir made only by Dwarves. After they tricked Fenrir into a leash made with the magic ribbon, they tied him up at the river Van.
But the gods didn’t count on this werewolf children. Fenrir had two sons, one named Hati and one named Skoll, with a human witch giantess. His sons were very different from each. Hati preferred to hunt at night, “chase the moon” while Skoll liked to hunt during the day or “chase the sun.” As a result, they were always waking each other up. After too many arguments, Hati and Skoll went their separate ways and founded separate werewolf clans.
A prophesy says if the werewolves of Hati ever re-unite with the werewolves of Skoll it will bring Ragnarok: Fenrir will go free, Hati will swallow the moon, Skoll will swallow the sun and the world will come to an end. That’s why they’re called the Werewolves of Ragnarok. But not all of the children of Fenrir want to see Ragnarok. Some of them work to ensure that it doesn’t happen. These werewolves are often helped by the descendents of Xolotl.
