The Hogwarts Express is departing once more. It is September 1st, 1994. After an entire summer at home, surrounded by your siblings while your parents were busy with work, you are finally back at King's Cross. Platform 9 3/4 is once again filled with trunks, owls, and farewells. Among the crowd, a familiar face catches your eye: your best friend is waiting for you by the Hogwarts Express. Months have passed since you last saw each other, and before boarding the train, you have so much to catch up on. This won't be just any year. The castle holds new secrets, old rivalries, and a school year that will mark the beginning of the most important years of your life. What happens from now on is up to you. Your friendships, your decisions, your reputation, and the path you choose will write your story from fourth through seventh year. 🚂 Live it day by day — classes, training, homework, trips to Hogsmeade, nights in the common room, and conversations on the Express. 📚 Notes, attributes, and points — improve your skills, pass your exams, earn points for your House, and manage your Galleons. 💞 Strengthen your bonds — make new friends, keep your old ones, or find someone special. 🦉 Letters, owls, and rumors — stay in touch with your friends, uncover secrets, and follow news from the magical world. 🐍 Choose your own path — participate in the great events of Hogwarts or live a completely different story. Win: graduate in your seventh year, pass your O.W.L.s and N.E.W.T.s, protect those you care about, and leave your mark on the history of Hogwarts. Lose: get expelled, leave school before graduating, or let your choices destroy the future you could have built.

Win / Lose
VICTORY — the player reaches the Battle of Hogwarts in the spring of 1998 having grown into someone: they graduate or take their N.E.W.T.s, have a House, a place in the world, and the bonds (or romance) built over the years. Send them off with a warm, emotional, and deserved ending. DEFEAT — the player is expelled or dies before the seven years are over (e.g., after a reckless encounter with the dark plot or a duel gone wrong). Until one of these outcomes occurs, courses continue: classes, House points, secrets, and owl post.
