Black magic

" But then?" Before Yakov could say any more admonishing words to Cassidy, Bree lazily raised her head and looked at the maid who was kneeling in front of her. Her gaze was light and she didn't look like she was threatening anyone ever so slightly but Cassius who caught her gaze shivered like a scared rabbit, this woman why was she so scary? Just look at those eyes, it looked as if she was going to eat him up in one gobble bite if he was to say one wrong thing!

Cassius somehow summoned his courage to open his mouth and say what he had in mind but no sooner had he parted his lips, Yakov turned to look at Bree and vociferously spoke, " Your majesty, you can't be listening to this nonsense!  What kind of explanation is it even,  I say that we need to take care of this maid lest others think that you are easy to attack!" 

Given that she chopped a huge mountain golem with just one move it was impossible for anyone to think that she was easy to attack.
