Hogwarts School of Witchcraft and Wizardry, first of September. The year does not need to be explicitly specified, but for the sake of the plot - let us assume it was some few years after Harry Potter's early departure from the School. Ten students have just arrived, ready to recommence their usual routines and balance studying with Quidditch, friendship and (for some) their patrolling duties as Prefects. They don't all necessarily know each other, but an unexpected and mysterious event will suddenly bring them together, to try and save the School from what seems to be an inevitable and harsh end. Will their courage and quick nerve be enough, or will Hogwarts have to close its imposing gates for good?
