Nobody knew who Uller's father was, and if he knew himself, he did not care to tell any one. He would not bestow many blessings upon mankind; yet thousands of people used to come to Ulrum every year to invoke his aid and ask him to send a heavy fall of snow to cover the ground. That meant good crops of food for the next year. The white snow, lying thick upon the ground, kept back the frost giants from biting the earth too hard. Because of deep winter snows, the ground was soft during the next summer. So the seed sprouted more easily and there was plenty to eat.

When Uller travelled over the winter snow, to go out on hunting trips, he strapped snow-shoes on his feet. Because these were shaped like a warrior's shield, Uller was often called the shield-god. His protection was especially invoked by men who fought duels with sword or spear, which were very common in early days; or by soldiers or hunters, who wished to be very brave, or had engaged in perilous ventures.

Now when Uller wanted a wife to marry him, he made love to Skadi, because she was a huntress and liked the things which he liked. So they never had a quarrel. She was very strong, fond of sports, and of chasing the wild animals. She wore a short skirt, which allowed freedom of motion to her limbs. Then she ranged over the hills and valleys with wonderful swiftness. So rapid were her movements that many people likened her to the cold mountain stream, that leaps down from the high peaks and over the rocks, foaming and dashing to the lowlands. They gave the same name to both this fairy woman and the water, because they were so much alike.

Indeed Skadi was very lovely to look at. It was no wonder that many of the gods, fairies and men fell in love with her. It is even said that she had had several husbands before marrying Uller. When you look at her pictures, you will see that she was as pretty as bright winter itself, when Jack Frost clothes the trees with white and makes the cheeks of the girls so rosy. She wore armor of shining steel, a silver helmet, short white skirts and white fur leggings. Her snow-shoes were of the hue of winter. Besides a glittering spear, she had a bow and sharp arrows. These were held in a silver quiver slung over her shoulders. Altogether, she looked like winter alive. She loved to live in the mountains, and hear the thunders of cataracts, the crash of avalanches, the moaning of the winds in the pine forests. Even the howling of wolves was music in her ears. She was afraid of nothing.

Now from such a father and mother one would expect wonderful children, yet very much like their parents. It turned out that the offspring of Uller and Skadi were all daughters. To them--one after another--were given the names meaning Glacier, Cold, Snow, Drift, Snow Whirl, and Snow Dust, the oldest being the biggest and hardiest. The others were in degree softer and more easily influenced by the sun and the wind. They all looked alike, so that some people called them the Six White Sisters.

Yet they were all so great and powerful that many considered them giantesses. It was not possible for men to tame them, for they did very much as they pleased. No one could stop their doings or drive them away, except Woden, who was the god of the sun. Yet in winter, even he left off ruling the world and went away. During that time, that is, during seven months, Uller took Woden's throne and governed the affairs of the world. When summer came, Uller went with his wife up to the North Pole; or they lived in a house, on the top of the Alps. There they could hunt and roam on their snow-shoes. To these cold places, which the whole family enjoyed, their daughters went also and all were very happy so far above the earth.

Things went on pleasantly in Uller's family so long as his daughters were young, for then the girls found enough to delight in at their daily play. But when grown up and their heads began to be filled with notions about the young giants, who paid visits to them, then the family troubles began.

There was one young giant fairy named Vuur, who came often to see all six of Uller's daughters, from the youngest to the oldest. Yet no one could tell which of them he was in love with, or could name the girl he liked best; no, not even the daughters themselves. His character and his qualities were not well known, for he put on many disguises and appeared in many places. It was believed, however, that he had already done a good deal of mischief and was likely to do more, for he loved destruction. Yet he often helped the kabouter dwarfs to do great things; so that showed he was of some use. In fact he was the fire fairy. He kept on, courting all the six sisters, long after May day came, and he lengthened his visits until the heat turned the entire half dozen of them into water. So they became one.

At this, Uller was so angry at Vuur's having delayed so long before popping the question, and at his daughters' losing their shapes, that he made Vuur marry them all and at once, they taking the name of Regen.
