The Danaans were the people of Dana, the goddess often referenced in Irish medieval romances. They were one of three Nemedian families who lived through the Formorian victory, later returning to Ireland. Some said that they came "out of Heaven" and others believed that they sprang from four cities in which they were taught science and craftsmanship. Each of them was said to have brought a magical treasure from the cities. From Falias it was said that they brought the Stone of Destiny, from Gorias they took an invincible sword, a magical spear from Finias and the Cauldron of the Dagda from Murias.
It was said that they wafted their way to Ireland on a magical cloud, carrying their treasures as they went. They gained all of Ireland except for Connacht after a victory in battle, and they represented power and beauty, poetry and science and they were earthly gods to the common people. They used their magical powers to triumph in battle.
