Once upon a time there was a boy and a girl who lived in an underground village. It was dark where they were. It was a cave. They heard stories of the outside, and wanted to go and explore. The people in this village had a custom that a male and a female would be intended for each other, and when they had reached 12 years old, both of them would work together to reach the surface. They were given no more training than this.
I see a lad digging through the surface, his muscles strengthening as he keeps simply going in one direction. He has a little candle to see by. Behind him is a lady who takes the dirt he digs through, and shores up the tunnel they make together. She stores the dirt, she strengthens the wall, she carries the light, she does all that she can to assist him.
They breach into the light, the man first, then the woman. They make a home together in the sunland. The man goes and hunts and makes advances in the world. The woman makes the home, and nurtures and helps.
They go back into the tunnel and return to the village when they have a child.
