'I will teach them what it means to put a lion in a cage'.
Cersei Lannister was the Queen Regent of Westeros. She is daughter of Tywin Lannister, and her brothers are Tyrion and Jaime (also her lover & father of her children). Cersei has always regretted not being born a man. After her son, Joffrey, was killed, she started to unravel, and thinks that Tommen's wife, Margaery, is trying to brainwash him. Her manipulative schemes fell apart, and all of her power was removed and was detained by the High Septon. She is currently awaiting her Trial by Combat.
