" Thor looked out on the two great rolling rivers of cloud. It was a bad way for one to go, cold and suffocating. Yet if he went that way he could keep on his shoulder the hammer which he would not leave in another's charge. He stept out into the Cloud River that flowed by the Rainbow Bridge, and with his hammer upon his shoulder he went struggling on to the other river.
Odin, Tyr, and Baldur were beside Urda's Well when Thor came struggling out of the Cloud River, wet and choking, but with his hammer still upon his shoulder. There stood Tyr, upright and handsome, leaning on his sword that was inscribed all over with magic runes; there stood Baldur, smiling, with his head bent as he listened to the murmur of the two fair swans; and there stood Odin All-Father, clad in his blue cloak fringed with golden stars, without the eagle-helmet upon his head, and with no spear in his hands.
