Pioneer of Wizarding World

[A Harry Potter Fanfiction] Alder Gray opened his eyes in a world both familiar and unfamiliar. He transmigrated to Harry Potter but seven years before the golden trio started Hogwarts. With the help of a system, which named itself Academic System, Alder's journey through wizarding world begins. Join Alder to discover if the existance of a system is merely a cheat, or a sign of great responsibility. ....................................................... Author's Notes: I do not own any character other than my OCs. Our first saga in the wizarding world will take place in 1984-1991, school years of our main character. A timeline which Hogwarts Mystery players may be familiar of. But most of the characters that has been added in the game are excluded. I'm writing the novel because of my admiration for Harry Potter series and I also hope to create an escape from daily problems for both myself and readers of my novel. But daily life and my job may also limit the update frequency, thus it has no definite update schedule. Last but not least, English is not my main language, be free to correct or warn me if you notice a mistake that disrupts your reading experience.
