There was one shadow which always fell over Asgard. Sometimes in the long years the gods almost forgot it, it lay so far off, like a dim cloud in a clear sky; but Odin saw it deepen and widen as he looked out into the universe, and he knew that the last great battle would surely come, when the gods themselves would be destroyed and a long twilight would rest on all the worlds; and now the day was close at hand. Misfortunes never come singly to men, and they did not to the gods. Idun, the beautiful goddess of youth, whose apples were the joy of all Asgard, made a resting place for herself among the massive branches of Ygdrasil, and there every evening came Brage, and sang so sweetly that the birds stopped to listen, and even the Norns, those implacable sisters at the foot of the tree, were softened by the melody. But poetry cannot change the purposes of fate, and one evening no song was heard of Brage or birds, the leaves of the world-tree hung withered and lifeless on the branches, and the fountain from which they had daily been sprinkled was dry at last. Idun had fallen into the dark valley of death, and when Brage, Heimdal, and Loke went to question her about the future she could answer them only with tears. Brage would not leave his beautiful wife alone amid the dim shades that crowded the dreary valley, and so youth and genius vanished out of Asgard forever.

Balder was the most god-like of all the gods, because he was the purest and the best. Wherever he went his coming was like the coming of sunshine, and all the beauty of summer was but the shining of his face. When men's hearts were white like the light, and their lives clear as the day, it was because Balder was looking down upon them with those soft, clear eyes that were open windows to the soul of God. He had always lived in such a glow of brightness that no darkness had ever touched him; but one morning, after Idun and Brage had gone, Balder's face was sad and troubled. He walked slowly from room to room in his palace Breidablik, stainless as the sky when April showers have swept across it because no impure thing had ever crossed the threshold, and his eyes were heavy with sorrow. In the night terrible dreams had broken his sleep, and made it a long torture. The air seemed to be full of awful changes for him, and for all the gods. He knew in his soul that the shadow of the last great day was sweeping on; as he looked out and saw the worlds lying in light and beauty, the fields yellow with waving grain, the deep fiords flashing back the sunbeams from their clear depths, the verdure clothing the loftiest mountains, and knew that over all this darkness and desolation would come, with silence of reapers and birds, with fading of leaf and flower, a great sorrow fell on his heart.

Balder could bear the burden no longer. He went out, called all the gods together, and told them the terrible dreams of the night. Every face was heavy with care. The death of Balder would be like the going out of the sun, and after a long, sad council the gods resolved to protect him from harm by pledging all things to stand between him and any hurt. So Frigg, his mother, went forth and made everything promise, on a solemn oath, not to injure her son. Fire, iron, all kinds of metal, every sort of stone, trees, earth, diseases, birds, beasts, snakes, as the anxious mother went to them, solemnly pledged themselves that no harm should come near Balder. Everything promised, and Frigg thought she had driven away the cloud; but fate was stronger than her love, and one little shrub had not sworn.

Odin was not satisfied even with these precautions, for whichever way he looked the shadow of a great sorrow spread over the worlds. He began to feel as if he were no longer the greatest of the gods, and he could almost hear the rough shouts of the frost-giants crowding the rainbow bridge on their way into Asgard. When trouble comes to men it is hard to bear, but to a god who had so many worlds to guide and rule it was a new and terrible thing. Odin thought and thought until he was weary, but no gleam of light could he find anywhere; it was thick darkness everywhere.

At last he could bear the suspense no longer, and saddling his horse he rode sadly out of Asgard to Niflheim, the home of Hel, whose face was as the face of death itself. As he drew near the gates, a monstrous dog came out and barked furiously, but Odin rode a little eastward of the shadowy gates to the grave of a wonderful prophetess. It was a cold, gloomy place, and the soul of the great god was pierced with a feeling of hopeless sorrow as he dismounted from Sleipner, and bending over the grave began to chant weird songs, and weave magical charms over it. When he had spoken those wonderful words which could waken the dead from their sleep, there was an awful silence for a moment, and then a faint ghost-like voice came from the grave.

"Who art thou?" it said. "Who breaketh the silence of death, and calleth the sleeper out of her long slumbers? Ages ago I was laid at rest here, snow and rain have fallen upon me through myriad years; why dost thou disturb me?"

"I am Vegtam," answered Odin, "and I come to ask why the couches of Hel are hung with gold and the benches strewn with shining rings?"

"It is done for Balder," answered the awful voice; "ask me no more."

Odin's heart sank when he heard these words; but he was determined to know the worst.

"I will ask thee until I know all. Who shall strike the fatal blow?"
