Who: Everyone Where: Great Hall When: October 31st, After the feast Warning: Bunch of teenagers are together. Nothing could go wrong, right? Status: Open. The Great Hall is decked out in all its Halloween glory. Candles and pumpkins float in the air and smells of yummy treats fill the room. The long tables that are normally in the Great Hall are gone, replaced with a single one along a wall. It is loaded with treats and drinks for the staff and students. There is a dance floor and the band Swish and Flick will be playing throughout the party. There is also an area with circle tables where people can sit and relax as they enjoy the fun.
