Persephone and her mother had a great relationship. They were loved because they brought good supplies and good weather. Things were good.
Persephone was out in a meadow with her friends one day and wandered off. The sky became dark and she got kidnapped by Hades, the underworld king. He wanted her to be his queen. At first she didn't exept.
Hades gave Persephone a tour of the underworld. After a few days, Persephone began to like it there. Her hope and light shined onto the ugly world.
Persephone's mother had Zeus sent his messenger down to get her. By the time he got down there, he was just in time to watch Persephone eat some food from the underworld. 6 berries.This is bad! He asks Hades to let Persephone come back up to her mother.
They made an agreement. Hades made the deal that since Persephone ate 6 berries, she would stay with him for 6 months of the year. She would stay with her mother the other 6 parts of the year. This is why we have bad weather for 6 months and good weather for 6 months. Now she can visit both of them!
