Quote by J.K. Rowling: “From all that I’ve read, what Harry did to Ridd...”
As J.K. Rowling put it, he was just poisoned a little, then cured.

Since we know that finding artifacts will be part of the game, it is reasonable to think Horcruxes will be among them. Now there are many ways in which this could be introduced into the game. He was also the creator of the first Horcrux. The knowledge of Horcruxes, and the magic behind them, are kept secret from the wizarding world. In fact, very few witches and wizards are even aware of its existence or nature. Even Hogwarts, a place created to educate young witches and wizards, banned the study of Horcruxes. The subject is, in fact, considered so widely as evil, that academies heavily focused on the Dark Arts, such as Durmstrang, will not touch upon it.
