It might perhaps help you by giving you the reign of control over your body and mind that you seek. It might give it to the beast that wears your skin. It might do nothing, or it might make a whole being out of your splintered self. Whichever way, the effects are temporary, and even if it causes some unforeseen effect, it will not last.
