Then there was silence in the field of the Dead, and Odin turned Sleipner, his steed, and for four days, through the gloom and silence, he journeyed back to Asgard.
Frigga had felt the fear that Odin had felt. She looked toward Baldur, and the shade of Hela came between her and her son. But then she heard the birds sing in the Peace Stead and she knew that none of all the things in the world would injure Baldur.
And to make it sure she went to all the things that could hurt him and from each of them she took an oath that it would not injure Baldur, the Well-Beloved. She took an oath from fire and from water, from iron and from all metals, from earths and stones and great trees, from birds and beasts and creeping things, from poisons and diseases. Very readily they all gave the oath that they would work no injury on Baldur.
Then when Frigga went back and told what she had accomplished the gloom that had lain on Asgard lifted. Baldur would be spared to them. Hela might have a place prepared in her dark habitation, but neither fire nor water, nor iron nor any metals, nor earths nor stones nor great woods, nor birds nor beasts nor creeping things, nor poisons nor diseases, would help her to bring him down. "Hela has no arms to draw you to her," the Æsir and the Vanir cried to Baldur.
Hope was renewed for them and they made games to honor Baldur. They had him stand in the Peace Stead and they brought against him all the things that had sworn to leave him hurtless. And neither the battle-axe flung full at him, nor the stone out of the sling, nor the burning brand, nor the deluge of water would injure the beloved of Asgard. The Æsir and the Vanir laughed joyously to see these things fall harmlessly from him while a throng came to join them in the games; Dwarfs and friendly Giants.
But Loki the Hater came in with that throng. He watched the games from afar. He saw the missiles and the weapons being flung and he saw Baldur stand smiling and happy under the strokes of metal and stones and great woods. He wondered at the sight, but he knew that he might not ask the meaning of it from the ones who knew him.
He changed his shape into that of an old woman and he went amongst those who were making sport for Baldur. He spoke to Dwarfs and friendly Giants. "Go to Frigga and ask. Go to Frigga and ask," was all the answer Loki got from any of them.
Then to Fensalir, Frigga's mansion, Loki went. He told those in the mansion that he was Groa, the old Enchantress who was drawing out of Thor's head the fragments of a grindstone that a Giant's throw had embedded in it. Frigga knew about Groa and she praised the Enchantress for what she had done.
"Many fragments of the great grindstone have I taken out of Thor's head by the charms I know," said the pretended Groa. "Thor was so grateful that he brought back to me the husband that he once had carried off to the end of the earth. So overjoyed was I to find my husband restored that I forgot the rest of the charms. And I left some fragments of the stone in Thor's head."
So Loki said, repeating a story that was true. "Now I remember the rest of the charm," he said, "and I can draw out the fragments of the stone that are left. But will you not tell me, O Queen, what is the meaning of the extraordinary things I saw the Æsir and the Vanir doing?"
