People Are at Hogwarts, Learning Ancient Magic

"The courses at Hogwarts are very rich, including potions, herbs, spells and Defense Against the Dark Arts..." "When you reach senior grades, you will also learn advanced magic like apparation." Hermione introduced the Hogwarts courses to Lucian non-stop, much like a teacher selling courses. Lucian: "What about Egyptian transfiguration, Persian constellation magic, Greek curses, runes and Chinese alchemy? Don't you teach them?" Hermione: "As we all know, ancient magic is lost, not even Voldemort." Lucian: "Then I feel relieved, because technology is in the hands of civilization." Hermione: "Say it as if you have learned ancient magic." Lucian: "Of course I don't know how, but if Muggles come over, will this little magic be enough now?" Hermione: "Muggles don't even know wizards exist." Lucian: "Is it possible that they already know, but are pretending not to know?"
