Mount Olypus was home to the 12 and many more gods. But annually there would be a little reunion. And that was today.
Now. Long long thousands of years back on a journey through the Earth the God of the Underworld Hades fell in love with a maiden picking flowers on the fields along with nymphs and other goddess. Never having felt such a strong desire and possessiveness he decided to take her by force. Kidnapping goddess Persephone and taking her to the Underworld, Demeter was engranged and an everlasting winter was cursed onto earth. Other gods noticed the life and land of earth dying and decided to go confront Hades... and after a long fight they had come to peace. Persephone would stay with Hades for 6 months and for 6 months with Demeter and soon... during her time she and Hades had fallen in love and now. Let's just say they're married and now the queen of the Underworld.
Hades and his Brothers with some other goddesses were all in a huge hall room enjoying an annual Olympus event. Where gods, goddesses, demi-gods and other creatures could come. Meet and enjoy themselves
