The Aesir's terror grew more and more, and no one saw a way out of the situation. Nagle, just as the builder was bringing the last batch of building material, a beautiful mare appeared nearby. Stranger's stallion, Swadelfari, hearing her neigh, he grabbed the harness and followed it into a nearby forest. The stranger rushed in pursuit, but he searched all night in vain, He did not find the horse. So the deadline passed and the first day of spring came. Freyja was saved. In the morning, and granic Asgardu, the builder appeared. In anger, he accused the gods of deception and accused them, that it was they who released the mare on purpose, preventing him from finishing his work within the set time. As, how anger began to take over his mind, the spell passed and the stranger began to lose his present form, taking his proper appearance on Thursy - Frost Giant. Then Thor killed him. This is how the gods possessed the impregnable fortress, closed to all evil, and the world was blessed with the warmth of the sun and the glow of the moonlit nights. But who helped the gods, sending a mare, even Odin himself did not know. Some time has passed, and Loki appeared at the gates of Asgard, leading an eight-legged steed. It was called Sleipnir. He had this wonderful ability, that he could move like that in the air, as well as on the ground, and faster than the wind. Loki gave it as a gift to Odin and from then on the sound of his hooves was heard over the world, as god went out to battle. Loki confessed to it, that it was he who turned into a mare, and Sleipnir is the son of him and of Swadelfari, the builder stallion.
For the help given to the gods, seeing Loki's abilities and power, Odin entered into a blood brotherhood with him and accepted him into the group of the Aesir. Many times later, Loki, thanks to his cunning, saved the gods from various oppressions, but in the end it became the cause of disaster, which plunged the Asi into mourning and brought the day of Ragnarok closer. For despite his appearance of kindness, Thurs's nature was often overpowering him.
