Hel, who dwelt under one of the three roots of the sacred ash Yggdrasil, was the daughter of the wicked Loki. Hel, together with her brother, the wolf Fenrir, and the serpent Jormundgand, was brought up in the giants' home of Jotunheim, where she remained until, at the request of the gods, Allfader sent for her and her brothers to destroy them, as it was known that by their origin they would prove the instruments of calamity. After casting the serpent that surrounded all lands into the deep ocean, he hurled Hel into Niflheim, and gave her authority over nine worlds, in which she was to assign places to all who died of sickness and old age. Her abode was surrounded by a high enclosure and massive gates. She was of fierce aspect, was inexorable, and would set no one at liberty who had once entered her domain. Her dish was hunger, her knife starvation, her servants slow-moving, her bed sickness, and her curtains wide-spread misery. With Ymir perished all the giants except Bergelmir. It was a popular belief that, through the power of giants, mountains and islands were raised, and that, by these monsters, mountains and rocks were hurled from their original sites. Notwithstanding the huge bulk and the number of heads and arms that many of the giants had, they were supposed to be ignorant monsters, unable to cope with ordinary human beings. The Dwarfs, of whom an account is given in the _Eddas_, were cunning and crafty elves, and skilled in magic. Some gave them a place between men and giants. It was believed that the dwarfs appeared under the forms of elves, brownies, and fairies. They used charms, and possessed all the skill of witches. It was in their power to raise storms, kill people by their diabolical art, fly away with children, and even with grown-up persons, through the air, or imprison them in caverns within the earth. They assisted men to discover the precious metals, of which they (the dwarfs) were very fond. Occasionally they were seen through an aperture of a hill, in their underground retreat, in palaces with jasper columns, surrounded with vast treasures of gold and silver.
