The Heavens: Hogwarts Transfer Students

On this day, the first-year Hogwarts freshman, the young savior Harry Potter, learned that a fifth-grade transfer student came to his college. He asked curiously: "Mr. Linde, where did you study magic before you transferred?"
Linde smiled slightly after hearing this, "I was the chief mage in Winterhold in the first grade, studied pyroxene magic at Rhea Lucaria College in the second grade, and conducted actual combat training in Middle-earth in the third grade. Years went to Candlekeep to build their mage tower at Baldur's Gate."
"That sounds incredible, so what are your plans for this year?"
"If you want to build a floating city, you have to set up your own secret religion. Maybe you can solve a little trouble for Professor Dumbledore by the way? For example, a certain Parseltongue is not very friendly."
