This idea came to me in a dream: what if the Potter family wasn't so … … … Light as we were led to believe? What if the Potter family had produced Dark Witches and Wizards that could make Voldemort appear to be nothing more than a kitten having a temper tantrum? The Potter family originated from Spain and had been dark before Spain had even become a unified country (15th Century) and were important assets during the Inquisition for their love of torture and they even invented new torture methods (i.e Strappado, the Rack, the Spanish Tickler, etc). When Harry came of age, he learns the truth of his family and discovers he to loves torture, the more pain it causes, the better.
