The Tuatha Dé Danann fight the Fir Bolg for Ireland and win; however, Nuada loses and arm and therefore the kingship. Bres then leads the Tuatha Dé Danann.
The Tuatha Dé Danann are a group of descendants of the Vanir that got tired of being confined to The Heavens. After they manage to escape from the Norse Continent, they arrive in Ireland. The current residences are the Fir Bolg whom the Tuatha Dé Danann request half of Ireland from. When the Fir Bolg refuse, the two factions go to war. When the Tuatha Dé Danann are victorious, they give the Fir Bolg a fourth of Ireland. During the victory, Tuatha Dé Danann leader Nuada loses an arm and is forced to step down, to be replaced by Bres.
