At Hogwarts, a new academic initiative forces students from opposing houses to collaborate on advanced magical theory. Y/N finds themselves assigned to an unstable mix of the Golden Trio and a Slytherin lineup known for intelligence, volatility, and zero compatibility. Their task is simple in theory: design a framework for stabilizing magic under emotional interference. In practice, the room they work in reacts to them. Conflict destabilizes the spellwork. Cooperation strengthens it. And every interaction becomes part of the experiment. What starts as a group project quickly turns into something far more dangerous: a controlled environment where the real subject isn’t magic. It’s them.
