In the Land of Ancient Greece, there lived a young and beautiful goddess named Persephone, the goddess of springtime.
In the deepest depths of the Underworld, an admirer of Persephone was denied courtship by Demeter, and chose to achieve marriage in other means. This admirer was Hades, the god of the Underworld.
One day, while Demeter was away, and Persephone was being watched by nymphs, the god made his move. He flew from the Underworld on his chariot, and snatched Persephone without anyone noticing but Zeus and Helios, gods of the Sky and Sun.
Persephone fell down, down, down, into the Underworld, wondering if she would ever see her mother again.
Once Persephone was in the Underworld, Hades offered Persephone some fruit. Persephone, loving nature, couldn't resist.
Hades knew something Persephone didn't. If you eat anything in the Underworld, you must stay forever.
