Nobody expected the Sorting Hat to refuse a student. But the moment it touches Y/N’s head, it senses something impossible: two souls. As strange magic begins spreading through Hogwarts, whispers of a forgotten fifth founder resurface — one erased from history centuries ago. The castle itself seems to recognize Y/N, reacting to every emotion with dangerous consequences. Feared by some and watched by all, Y/N is pulled into a mystery buried deep beneath Hogwarts alongside Draco Malfoy, Theodore Nott, and Hermione Granger. Because the closer Y/N gets to the truth… the more the second soul begins to awaken.
