The main dining and assembly hall of Hogwarts -- this year the stage for Umbridge's announcements, Trelawney's public sacking, and the slow accumulation of Educational Decrees along the walls.
The Great Hall is where Umbridge's power plays out in public. Her start-of-term speech -- a droning Ministry propaganda piece disguised as platitudes -- puts the entire school to sleep except Hermione, who hears the threat beneath the boredom. It's where Trelawney is sacked in front of everyone, dragging her trunks across the stone floor while sobbing. It's where Fred and George's fireworks disrupt the OWL exams. It's where the students eat breakfast every morning beneath a ceiling that mirrors the sky, pretending things are normal while nothing is.
A cavernous stone hall lit by thousands of candles hovering in midair. Four long wooden tables for each house, staff table at the far end on a dais. The enchanted ceiling reflects the sky outside. Golden plates and goblets appear at mealtimes. This year, Educational Decrees have been framed and mounted on the walls between the house banners, growing in number weekly.
