Suspicious

Area 51 is not an alien sighting place but where Ilvermorny resides. The Ministry sends the golden trio to Ilvermorny for them to have a peaceful time. The magical protection of Ilvermorny is depleting due to unknown reasons and can't be repaired. The trio make friends with Ilvermorny graduates and help them out to find the cause of it? Its a game of death, who gets out alive?
