Hogwarts Raven (Harry Potter)

The story begins. Ian thought he was just a little wizard with a small talent [cheat ability], who could become stronger through hard work. However... As the story unfolds, he gradually starts to realize that the teachers he’s been following to learn magic are either once-renowned powerhouses or characters mentioned in various legendary tales. “Standing before you is the noble apostle of the Shifting Illusions, the common spokesperson of the Old Ones, and the designated successor of the founders of Hogwarts!” “What? The noseless freak wants to stir up trouble? He must not have heard of my original spells, which are even recorded on the famous wizard collection cards in Chocolate Frogs!” “The Dumbledore Summoning Charm!” “The Dumbledore Berserk Charm!” Ian chants the "Expecto Patronum" spell. Suddenly, silver-white threads burst forth and converge, forming the figure that had caused a certain professor to live his entire life trapped in guilt, standing protectively in front of him. — Description from novelcodex.org
