Can we make it be that humans are capable of even greater heights of magic than dragons or dark ones, but magic always requires sacrifice?<br/><br/>Presumably, Dark Ones get past sacrifice by taking the blood of humans and paying their sacrifice in advance that way, while Dragons get past sacrifice by utilizing the same mystical energy sources that power their fire breath and shapeshifting.  Probobly drawing upon ley lines or being part fair folk or something.  Dragons are probobly pretty limited in what they can do magically (being forced to spend decades, or even centuries learning new tricks), while Dark Ones can improvise new powers reasonably quickly, though their batteries run out faster.<br/><br/>Humans could be theoretically capable of anything, but tend to get brutally exploded into chunks when they try stuff.  (Hence why the knowledge of magic is occulted, for dragons to protect humans, and for dark ones to protect their food supply.)  Generally, a human provided with an unlimited arcane library will be dead within 6 months, and a major hazard to himself and others within 3.<br/><br/>Does that sound usable?
