The woman that does her voice work is a very talented VA and I doubt she came cheap. Her work includes being Morrigan in Dragon Age, Queen Marwen in Shadow of Mordor, Admiral Daro'Xen/Matriarch Aethyta in Mass Effect, Chloe Frazer in Uncharted, and Artemis in God of War along with more than a handful of voice work in other games and appearences in live action tv shows and movies. Someone with her work history doesn't come cheap.
