- ―Tommen to Cersei Lannister.
King Tommen I Baratheon (formal: King Tommen of the House Lannister, First of His Name), known pre-coronation as Tommen Baratheon, is the head of House Baratheon of King's Landing and Lord of the Seven Kingdoms. Tommen became king of the Seven Kingdoms when his older brother was murdered, although he was ill-equipped for the role. In the show, he eventually marries Margaery Tyrell, before briefly losing her to the Faith Militant, and later converted to the Faith. He was forced to watch his wife die in the destruction of the Great Sept, where he committed suicide shortly after. In the books, he is not yet of age to marry or rule, and Cersei Lannister has regency, at least until her arrest by the Faith.
