Hogwarts of Another World

Matthew Wickfield always believed he had transmigrated to the world of Harry Potter. His true identity was a young Muggle wizard about to attend Hogwarts. He guessed right, but also wrong in many ways. He would indeed go to Hogwarts, but it was no longer the warm, joyful, and innocent magical academy of his memories. Darkness had fallen, the Dark Lord's rule continued, mystery and fear spread, blood and death accompanied. And the only hope had long been imprisoned in the tower of Nurmengard.
