The Astronomy Tower group chat was supposed to be boring. It was created by Professor Sinistra so seventh-years could share homework reminders, telescope schedules, and star chart corrections. Instead, it had become the unofficial school gossip hub. Ravenclaws answered questions before professors could. Gryffindors argued with Slytherins. Hufflepuffs posted memes at 2 a.m. And everyone knew if something happened at Hogwarts, it’d end up there within five minutes. Tonight was different. Someone meant to send a message somewhere else. Instead, the entire Astronomy Tower chat watched a secret explode in real time. A single text. Then another.
