One day Hades, the God of the Underworld, happened to glance up at the world above and noticed Persephone playing with a group of nymphs in her fields. Hades was a just god, but he grew lonely and cold as he carried out his duties over the centuries. But as he observed Persephone, he was struck immediately by her beauty and her tenderness towards the nymphs. He ended up going back to watch her every so often, feeling his old heart soften each time.
