Hogwarts of Another World

Matthew Wickfield always believed that he had transmigrated to the world of Harry Potter. In reality, he was a small Muggle wizard about to attend Hogwarts. He guessed right, but also terribly wrong. He was indeed going to Hogwarts, but it was no longer the warm, happy, and innocent magic school in his memory. Night had fallen, the Dark Lord's reign continued, mystery and fear spread, blood and death were always close. And the only hope had long been imprisoned in the Nurmengard tower.
