Tywin Lannister (Charles Dance) Tywin Lannister is Lord of Casterly Rock, Shield of Lannisport and Warden of the West, the powerful and wealthy patriarch of the Lannister family.A calculating, ruthless, and controlling man, Tywin is one of the most powerful lords in Westeros and is not afraid to wield that power. He often buys loyalty, favors, and double-crosses from those willing to be bought.He is the father of Jaime, Cersei, and Tyrion Lannister and he has raised them in his cold, calculating image. He loves his children Jaime and Cersei, but despises Tyrion and does not try to disguise his disdain. His disgust stems partly from the fact that Tyrion is deformed as a dwarf, but also because Tywin blames his son for causing his beloved wife Joanna's death during his birth.Regardless of whatever misdeeds they may commit, Tywin is fiercely protective of his children and his family name and will do what is necessary to protect both.Tywin has an innate intelligence as well as a sense of book smarts. He can read people quickly. He does not suffer fools, especially those related to him and is often seen seething in disappointment at his children. Disappointment aside he is single-minded in his quest for retaining the power the family already has and gaining more.
