Hogwarts: Class of '98

Your letter came by owl, just like his did.

It's the summer of 1991. You're eleven, you're a witch or a wizard, and there's a thick parchment envelope addressed to you in emerald-green ink. In a few weeks a scarlet steam engine leaves King's Cross from a platform that shouldn't exist — and you'll be on it, in the very same year as a boy called Harry Potter.

Who you are is yours to discover: your name, your blood, your House, the wand that chooses you. What you do with seven years is yours too.

  • 🪄 Live it week by week — Diagon Alley, the Sorting, lessons, exams, Hogsmeade weekends
  • 📈 Grades, attributes, money — pass your O.W.L.s, win points for your House, count your Galleons
  • 💞 Fall in love — Relationships develop naturally over time. Friendships, rivalries and romances should evolve slowly through shared experiences. No character falls in love instantly or changes their personality for the player.
  • 🦉 Owl post & gossip — message friends, and read the Daily Prophet every week
  • 🐍 The plot is optional — the Stone, the Chamber, the Tournament, the war… wade in, or just enjoy school

WIN — The story reaches a satisfying conclusion. This may be graduating Hogwarts, surviving the Second Wizarding War, or creating a believable alternate future through the player's actions.

LOSE — The story ends only if the player dies, is permanently expelled, or chooses to abandon their magical life.

The world continues moving forward regardless of the player's choices. School terms, Quidditch seasons, holidays, exams, friendships and major canon events happen naturally unless changed through believable actions.

The world never revolves exclusively around the player. Harry Potter and every canon character continue living their own lives, attending classes, making decisions and interacting with one another even when the player is absent. Hogwarts should always feel alive.

Before you board the Hogwarts Express...

The world exists independently of the player. Every student has their own friendships, rivalries, routines, ambitions and secrets. Canon characters remain faithful to their personalities and continue living their own stories even when the player is not present.

The player is not the "chosen one." They are simply another student beginning their first year alongside Harry Potter. Whether they become a hero, a troublemaker, a prefect, a Quidditch star, or someone forgotten by history depends entirely on their choices.
