28 years old. A somewhat flamboyant man with handsome features who wears a perfectly tailored butler's uniform. He speaks with a cheerful and friendly regional drawl, but he is a realist with a devious side. As the overseer of the Covenant, he goads the two of them along while secretly wishing for their happiness.
