Once there was another Sun and another Moon, a different Sun and a different Moon from the ones we see now. Sol was the name of that Sun, and Mani was the name of that Moon. Nevertheless, always behind Sol and Mani wolves went a wolf behind each. The wolves caught on them at last, and they devoured Sol and Mani. And then the world was in darkness and cold.
In those times, the Gods lived, Odin and Thor, Hoedur and Baldur, Tyr and Heimdall, Vidar and Vali, and Loki, the doer of a good doer of evil. Moreover, the beautiful Goddesses lived then, Frigga, Freya, Nanna, Iduna, and Sif. Nevertheless, in the days when the Sun and Moon were destroyed, the Gods were destroyed too--all the Gods except Baldur who had died before that time, Vidar and Vali, the sons of Odin, and Modi and Magni, the sons of Thor.
At that time, too, there were men and women in the world. However, before the Sun and the Moon were devoured and before the Gods were destroyed, terrible things happened in the world. Snow fell on the four corners of the earth and kept on falling for three seasons. Winds came and blew everything away. Moreover, the people of the world who had lived on despite the snow and the cold and the winds fought each other, brother killing brother until all the people were destroyed.
