Thousands of years ago the Tuatha Dé Danann – the People of the Goddess Danu – landed on the West Coast of Ireland.
Their boats suddenly appeared out of a huge mist. People thought they came from the sky and believed they must be half gods, half human.
They brought four great magical treasures, fought and won fearsome battles and ruled Ireland for more than 400 years.
And when their reign was over, they vanished into the Other World, still exercising their magic powers, living on forever.
