Balor
From Tardis Wiki, the free Doctor Who reference
Balor was worshipped as a chaos god by the Cynrog. While escaping from a war, Balor crashed in Yns Du in the 1930's and his consicousness became embedded in Nathaniel Morton, Bronwyn Ceredig, and five others. Using children's bad dreams and worries, Balor was reserrected. He was killed shortly afterwards. (NSA: The Nightmare of Black Island)
