For casuals, the name Herpo the Foul isn’t going to mean a lot, and that’s because his origins come from the deepest parts of Harry Potter lore. But those who do know the name will also know that he was one of the darkest wizards in wizarding history, the man (if you could call him that) credited with creating the very first Horcrux—crossing a magical line so horrific most witches and wizards barely discuss it.

But Herpo didn’t stop there, as he actually went on to conduct more and more twisted dark arts experiments, crossing lines regularly that no other wizard ever dared. To this day, his name is associated with some of the most disturbing and unnatural magic the wizarding world has ever seen.

Now, what if I told you that he knew Hagrid?
