In the highest branches of a fictional tree lives a bunch of gods, most of whom have long and hard-to-pronounce names. One of them, however, has a somewhat easy-to-pronounce name, and his name is Tyr. Not Thor. This is a different guy.
Anyway. Tyr is really good with a sword. In fact, I'm pretty sure he's the Norse god of war--at least on of them. But Tyr is also super brave, brave enough to befriend the scariest thing that lives in the highest branches of the fictional tree: Fenrir.
Fenrir is a piece of work. His mother is a giant, and his father is a god. Loki, actually. Remember how I mentioned he had two non-human kids? Fenrir is one of them. Fenrir is a wolf. And, as luck would have it, a pretty big and scary wolf. That must be the giant blood in him.
Fenrir, in fact, is so big that most of the gods avoid him. But not Tyr. Tyr treats him like an oversized German Shepherd and plays with him in the sunny afternoons. He probably gives him belly rubs, too.
Unfortunately, as Fenrir keeps growing, the other gods decide Fenrir needs to be locked up. So they go up to him and say, "Hey, buddy! Here's a super-strong chain. Let's tie you up with it and see if you're strong enough to get out." So they tie him up, and Fenrir breaks the chains. Piece of cake.
So the gods get a bit more concerned. They go to the dwarves and have them make another chain--a stronger one this time. And, just like Sampson and Delilah, Fenrir breaks out of this chain, too.
So the gods sit together and think--not exactly something the Norse gods are known for--and they finally decide to ask the dwarves for a magic chain. So the dwarves go around and gather up bird spit, women's beards, the sounds of a cat's footsteps, and fishes' breath. And they make a nice, soft rope out of all these things. Somehow.
So the gods go find Fenrir again. He's romping with his buddy Tyr, probably playing fetch with Thor's hammer or something. After a few more rounds of fetch--because why not, the poor dog's getting locked up anyway--the gods find Fenrir and ask for one more test of his strength.
This time, Fenrir's a bit suspicious. So he asks that one of the gods place their right arm in his mouth, as proof that no one's trying to trick him. Tyr volunteers.
It's a trick. Obviously.
The highest branches of the fictional tree are now a safer place because Loki's son is locked up. Tyr learns how to sword fight with his left hand. And--with the exception of Fenrir--everyone in the highest branches of the fictional tree is happy.
