A God named Don and a Goddess named Danu had an unbreakable bond. Then they bore children. But the children could not escape and were slowly dying. One of the siblings named Briain chopped his father to nine pieces.
HIs head became the skies, his brian the clouds, his face the sun, his mind the moon, his bones the stones and his breath the wind.
Two acorns fell to Earth. One grew into an oak tree and became the reincarnation of Don. The other became his brother Finn the priest.
Berries from the oak tree grew into the first humans. The humans were very lazy because couldnt die.
Finn and Don had a fight over should the humans experience death. Both Finn and Don died in the fight. Don's death created the other world were the humans sent when they died.
Although Danu and Don were separated there love continued even though they were blocked from the earth.
