The King was getting paranoid, adding more hybrid-men to his guard.... Of course, she WAS attempting to sneak into the castle to steal the King's favorite chalice. Why? She didn't know. But the buyer was offering an obscene amount of money for the cup... Who was she to tell him 'no'? Some people had strange tastes and she wasn't one to quibble. It was none of her concern except to steal the thing.
