"Why", puffed Neville, "are the classes being held in the great hall anyway? And why is there a platform hung twenty feet off the ground for our desks?"
"I don't see why we have to clamber up ladders like stupid Muggles to get to class, can't we use brooms!" A murmur of support came from below Malfoy, possibly the first time in history of Hogwarts the young Slytherin had mass support from his classmates.
Finally the class had hauled themselves up onto the great platform that now formed their classroom, with various degrees of athleticism, and collapsed into their seats ready to greet the new Professor. The doors to the hall swung open and the students looked the new Defence teacher square in the chest. Silence rolled out across the improvised classroom, broken only by Hermione banging her head into the desk in frustration and quietly sobbing about the world not making sense anymore.
"Greetings young humans, I am Professor Optimus Prime, and we shall begin with discussing the proposition that freedom is the right of all sentient individuals, and that there is more in this world than meets the eye!"
Up in his office, Dumbledore sat considering Sybill Trelawney's latest prophecy "One shall stand, one shall fall!" and wondered if he had really done the right thing.
