The third was the Fenrir wolf, still a puppy, but at the time of birth he was terrified by his appearance. Loki took the children, like every father with love. He was even proud of their size and power. He only feared, how the Aesir would receive news of their birth. Odin, when he saw what she gave birth to Loki Angrboda, he fell into horror. For he understood, that the words of the clairvoyant Voluta are fulfilled and the day of Ragnarok is approaching. He was all the more afraid, that Loki's offspring still lived among the giants, and that could not be any good for the world.
So the gods gathered for a council and ordered Loki to bring the children to Asgard. Reluctantly, he submitted to the assembly sentence, because he felt a trick in it. So he made a vow on Asah, that they will not be killed.
When the gods saw the formidable offspring of Loki, they wanted to kill them. However, he remembers the oath, they threw Midgardsorm into the depths of the sea, and he immediately girded the earth with his body, and, grabbing the mouth of the tail, closed the circle. They threw Hel into the deepest worlds, giving her the kingdom of the dead. The unhappy herself takes care of them, who died in the bed. However, she was forbidden to return to the world. He will come, when the time is up and the ragnarok will come. Fenrir was held by the gods in Asgard for the time being. Here it grew and grew stronger, until he became so monstrous, that only one Tire was not afraid to give him food.
Remember the prophecy, that the wolf would become the gods' doom, the Aesir decided to protect themselves. Bound by an oath, unable to kill the wolf, they resolved to bind him with such ties, which he couldn't break, until the Last Great Battle. But who was to bind him? ? Even Tire lacked the courage for that. Odin decided to use a trick. So they forged a magic chain called Larding and made a bet with Fenrir, arguing, that this one does not have enough strength, to break it off. A wolf self-confident in his power, he allowed himself to be fitted and easily seized the ties. The gods had now made the Drom chain, putting all my magic in it.
