Intro - Fundamental Laws of Magic -
“Tamper with the deepest mysteries the source of life, theessence of self only if prepared for consequences of the most extreme and dangerous kind.”
--The first law
The Fundamental Laws of Magic are, presumably, a number of statements about the general nature of magic. They were formulated by the magical theoretician Adalbert Waffling, the first of which is quoted above. Some examples of the broken law below:
The Hairy Heart
The Heart of a handsome, skilled, and rich young Warlock was cut out of his body and placed in an enchanted casket. During the heart’s long incarceration away from the Warlock’s body, it grew shriveled, shrunken, and covered with black hair. This also symbolizes the warlock’s own descent into beasthood due to his attempts to live without love.
The tale goes as: A young Warlock was embarrassed to see his friends falling in love and considered the act foolish and weak. He decided that he never wanted to fall victim to love, and secretly used Dark magic to cut out his heart.
He lived on, seeming content with his lack of emotion, not even mourning when his parents passed away. After their deaths, he moved into their home and transferred his heart, his “greatest treasure,” to the dungeon. Believing in the perfection of his solitude, he was shocked to overhear one of his servants pitying him, and another thinking it funny he didn’t have a wife. He decided he would go out and find the most beautiful, talented, wealthy and all-around enviable young woman to be his bride. The very next day, the young Warlock had the fortune of meeting the perfect woman. He began pursuing her, convincing all of his friends that he had changed. She was both “fascniated and repelled” by him, and agreed to attend a feast at his home. While at the feast, the maiden asked the Warlock for proof that he had a heart. He took her down into the dungeon and showed her the magic crystal casket that held his beating heart. The woman was horrified at the sight of it, as it had grown hairy and shrunken as a result of its separation from the Warlock’s body. She begged him to replace the heart within himself, so he sliced his chest open with his wand and placed his heart back into his chest. As the woman embraced him, his heart, which had grown blind and perverse, took savage action against the young woman and killed her.
When the rest of the guests went looking for the Warlock, they found him in the dungeon, crouched over maiden’s lifeless body, caressing her heart. He attempted to take her heart for his own, but his heart was too strong and would not leave his body. Determined never to be mastered by his heart again, he cut it out of his chest, and fell over the maiden’s body, dead.
Another example of the hairy heart is having a child under the Amortentia potion. As in the infamous case of Lord Voldemort, having a child under the effects of this potion has dire consequences. The baby may be either mutated in body or spirit. In the case of the Dark Lord, the effects of this broken law had created him a human incapable of love, a lonely path to take.
