William traveled to the world of Harry Potter, but got the wrong birth point. Because his pen name was exposed, he suffered a social death and eventually transferred to Hogwarts. "Latin is the best magical language, but I will always prefer ancient runes." "Of course, Ilvermorny is a good school and the beds are very comfortable." "I left Paris because I was disappointed with the laxity of this city, not because I was banned from entering the French Ministry of Magic! It had nothing to do with the bombing of Père Lachaise Cemetery! I reiterate that the Sacré-Coeur was just an unfortunate accident!" --The alchemist of the Double Jubilee Year, the initiator of the industrialization of magical creatures, the never-welcomed guest of the French Ministry of Magic, the first-class medal winner of the Order of Merlin (former), "Detailed Explanation of the Rune Array", "Introduction to the Magic Industry", "New Materials and Synthesis of Magic Superconductors", "Discussion on the Possibility of the Magic Internal Combustion Engine"...
