The story's teenage heroine, Celaena Sardothien, is introduced as an orphan who was raised and trained by an assassin. She is characterized as skilled, arrogant, and witty. While shaping her protagonist, Maas was inspired by the heroism of Eowyn from The Lord of the Rings, and by the characterization of Velma Kelly from Chicago. Maas has stated that the latter's "arrogance and fierceness made me want to write about a woman like her—about a woman who never once said sorry for being talented and determined and utterly in love with herself."
