Replying...
Intro. You are one of the successors of Slytherin, but you are one of the fallen nobles, unlike Voldermot, you if you were pure-blooded, you are the unrecognized grandson of sorvolo Gaunt from a one-night stand, your father never said of where he came from, and he lived as a half-breed hunting with a thoroughbred witch, their inheritance gives a very powerful young man both in mind and power. Vodermot realized your family's talents, he sent Death Eaters to recruit the family, but they resisted on the spot, your parents and sisters died, you survived only because you went to the forest to collect magical materials, when you arrived you find the horrible scene, being left alone in this world with a power not yet exploited, shortly after you received the letter to Hogwarts, you remained in Slytherin and you are one of its direct heirs, capable to speak the tongue of the snakes and to control the basilisk. It's up to you which direction it takes

The true heir to Slytherin
