The story of the Tuatha de Danaan 

It was in a mist the Tuatha de Danaan, the people of the gods of Dana, or as some called them, the Men of Dea, came through the air and the high air to Ireland.
It was from the north they came; and in the place they came from they had four cities, where they fought their battle for learning: great Falias, and shining Gorias, and Finias, and rich Murias that lay to the south. And in those cities they had four wise men to teach their young men skill and knowledge and perfect wisdom: Senias in Murias; and Arias, the fair-haired poet, in Finias; and Urias of the noble nature in Gorias; and Morias in Falias itself. And they brought from those four cities their four treasures: a Stone of Virtue from Falias, that was called the Lia Fail, the Stone of Destiny; and from Gorias they brought a Sword; and from Finias a Spear of Victory; and from Murias the fourth treasure, the Cauldron that no company ever went away from unsatisfied.
