by ships and inhabited the country before the native Irish. They came to Ireland to take the land from the Fir Bolgs that had already been residing in the north of Ireland at the time. The Tuatha were immediately perceived as gods for their superior skills: various arts of druidry, magic, prophecy and history. Their leader was named Nuada. He led them to war against the Fir Bolgs around the west shore of Ireland, where the Tuatha had arrived by ship. Many of the Tuatha died in this war, but thousands of Fir Bolgs died. Including their leader, Eochai Mac Erc. They come from another world, but reside in Ireland until they were pushed out by war with a semi-demonic race called the Fomorians. Their king is known in the mythology as Balor. The Fomorians resided on the outskirts of Ireland. When the Tuatha Dé Danann were defeated in battle against the Milesians, they were forced to live underground in the Sidhes. The Sidhes were chambers under Ireland's surface. Though away from the mortal world, they still would come to surface on special days like Hallowe'en and May Day.
