Hogwarts announced a new Halloween tradition: the **Partnered Costume Unity Festival**. Instead of competing, students from different houses were paired by enchanted scrolls that fluttered through the Great Hall, matching Gryffindors with Slytherins, Ravenclaws with Hufflepuffs, and every combination in between. Each pair had to design a themed costume set—heroes and villains, historical witches and wizards, mythical creatures, or perfect opposites.
