Thanks to movies like Thor many people are becoming better acquainted with Thor, Loki, and Odin, but there’s a whole world of Norse mythology that many people don’t know about.

Norse mythology is one of the richest in the world, with many people still worshiping the “old Gods” in Scandinavia.

One story from Norse mythology that is a little less-known than the story of Loki is the story of his son, Fenrir.

Fenrir is the reason that one of the names for Loki is “Father of the Wolf”. Fenrir is a massive, powerful, demonic wolf in Norse mythology. He is also known as Hróðvitnir (“fame-wolf”), Fenrisúlfr (“Fenris wolf”), and Vánagandr (“Monster of the Van river”). The name “Fenrir” roughly translates to He Who Dwells in the Marshes”. He is the offspring of Loki and the giantess Angrboða – the Herald of Sorrow.

Angrboða and Loki would have three children in all – Fenrir, Hel, and Jörmungandr. Fenrir would go on to have two children of his own; Skoll and Hati. Skoll and Hati are destined to chase the sun and the moon respectively until the fall of Ragnarök, at which point Skoll will devour the sun and Hati will devour the moon. This brings to light an ancient attempt to spiritually explain what, at the time, was unexplainable, i.e. our rotation around the moon.

There are plenty of wolves in Norse mythology but none of them are as massive or powerful as Fenrir. Fenrir is also the most infamous wolf in the mythology. He is depicted on a number of rune-stones that survive from the old days, and there are many stories written about him; particularly in the Old Norse writings of the pre-Christianity era of Scandinavia.

The Story of Fenrir

Fenrir, much like his siblings Hel and Jörmungandr, would be kidnapped by the Aesir (Odin, Thor, etc.) and raised as one of their own to keep their powers in check. All of Loki’s children had the power to wreak havoc across the Nine Worlds, so the Aesir thought it best to try to contain them. They had trouble with Fenrir, however, as he would not stop growing. They attempted to bind Fenrir using chains. They tricked Fenrir, telling him that it was just a test of his strength, and unfortunately for the gods, he certainly proved his strength as he broke through the first two bindings the Gods had prepared for him.

The Gods were undeterred by their failures, and had the dwarves create the most powerful chain ever made. The chain was called Gleipnir, and it was forged from the roots of a mountain, the sound of a cat’s footfall, the breath of a fish, the beard of a woman, the spittle of a bird, and the sinews of a bear; all of which are supposed to be impossible to obtain.

It was designed to still be light and even a little soft. Fenrir was suspicious when presented with this third chain. He said that he would only put it on if one of the Gods would place their hand into his mouth as a sign of good faith. The only God who was brave enough to do this was Tyr. Tyr knew that doing this would mean losing his hand, which is just what happened when Fenrir discovered that he was unable to break free of the third chain.

After successfully binding Fenrir, the Gods attached the chain to a boulder and placed a sword in Fenrir’s jaws so that they would remain open. That way the great beast would be unable to bite down on anything again. Fenrir howled incessantly, causing the creation of the River Van (Expectation) from his spit, hence the nickname “Monster of the Van River”.

Even though he was bound by the Dwarven chain, Fenrir, even then, never stopped growing. The stories of Fenrir say that, much like his sons, he will continue to have a part to play in Ragnarok. The legends say that one day Fenrir will break free at Ragnarok and he will run through the world with his mouth open wide. He will devour everything he runs into and will even kill Odin, before being killed by Víðarr; an avenging son of Odin. Víðarr will kill Fenrir by ripping his jaws apart.

Fenrir may be the most powerful of all the Norse wolves, but there is evidence to suggest that some of the other wolves in Norse mythology could also be Fenrir. For example, there is one version of the tale of Ragnarok where Fenrir is the one devouring the sun; suggesting that he could be Skoll rather than Skoll being his son. Another one tells the story of Garmr; a wolf who breaks his chains during Ragnarok and is almost definitely Fenrir.

There is another version where Fenrir is actually Hati, his other son. In this version the wolf who eats the moon goes by the name Mánagarmr – which translates to “Moon Eating Wolf”. So not only could Fenrir be the one who destroys most of the world and kills Odin during Ragnarok, he could also be the one who eats the sun and the moon. Given that Fenrir is the son of Loki, the trickster God, it wouldn’t be that surprising if he pretended to be his own sons, or if they were extensions of the original body trapped in Asgard.


There are numerous references to Fenrir in modern popular culture. For example, the characters Fenrir Greyback in Harry Potter and Fenris in the video game Dragon Age 2 are both named after the Wolf God. As monstrous as Fenrir is, there’s no need to worry as he will be chained in Asgard until Ragnarok. Given that Ragnarok is the fall of the gods and the end of the world, there will be more pressing matters than a giant wolf devouring the planet and killing the All-Father.
