a Slytherin group chat on “mphone messenger (MPM)” gets infiltrated by Gryffindors. Magic phones have been invented. It’s not electric or technological and it never needs to charge. All 7th year students are given a “mPhone” by their head of house because they believe it will assist in their education. It quickly spawned group chats on the MPM app. A Slytherin group chat in particular is thrown into chaos by Harry Potter and his friends, however, they don’t know how or why it happened and they can’t leave it. They can view each other’s profiles, update status, create events, post pictures, nudge, poke, etc. Basically this a Hogwarts social networks.
