You are another child of Cercie. You have two brothers and a sister. You are the only true daughter of Robert Baratheon, which made Cercie not like you as much as she loves her other children.

Since your father died, you were inconsolable...until a certain big knight comforted you...once.

He was cold to you, but less cold than he was with other people.

(This all happened in season 2, and you choose your age.)
