Sen Mag Prairie is a grassland in central Uladh and also a historical battlefield. In Irish, Sen Mag means Plain of Birds. It was the location of an age-long conflict between the Tuatha de Dananns and Fomorians; the most famous battle took place was called the Second Battle of Mag Tuireadh. It holds many unnamed graves for those killed in the battle, and there have been many unverified ghost sightings in the area. The wholesale destruction which took place left the region barren and uninhabited, although reports claim plant life is gradually recovering.
