Starting in a second floor corridor, transitioning outside.

At first, the staircase was silent. 

For Hogwarts, that was perhaps normal. For anyone from Salem, silence was a warning. Silence was the calm before the storm. Silence was, like a forest evacuated by all the wildlife, a bad sign.  The staircase, in the middle of moving, froze, as if it somehow sensed this and was trying to make itself as inconspicuous as possible in the hopes that whatever was coming might take a different route.

"Out. OUT!" Ferreole LeBeau's booming bellow was topped only by the horrible clattering howl of one very disgruntled Ford Anglia, rocketing breakneck and ferociously down the hallway, sending suits of armor scattering out of the way like chess pieces, tires squealing like a banshee.

The Salem headmaster rode on top of the car like a conquering avenger, wielding a broomstick like a mighty axe, and after a moment it was apparent why. The hood of the car suddenly slammed up, and out flew a well, whatever it was, that Ferreole promptly smacked out of the air with one very square hit and a bellowing war cry. "Yiiiiheeeheeehee," the one-legged man cackled like a mad hyena, wild and high pitched. A quick flash of purple light from his wand sent the critter barreling out of a window where it flapped furiously off into the direction of the forest. The car snorted, great big belches of gas and smoke, windows sliding up and down, hood lifting to smack into the windshield as another one of the creatures rose from the swarm, chittering madly from the hood to be smacked down and also out the window by Ferreole's broomstick.

As the car approached the staircase, with a practiced swoop, Ferreole caught one of his students in the stomach with the broom, sweeping him merrily on top of the madly charging car and handing him the broomstick before alleviating one of the suits of armor of its rather distressingly pointy halberd. "Look alive, boy! Aim for de little beasties! T'ink dat be de last one, but can't be too sure." He stomped once on the hood of the car with his peg leg. "Now den, all better?" He appeared to be addressing the car, rather than the student he had abducted, "Back outside den wit' jou, muggle contraption!"

Like a rocket, the car hurtled down the staircase at full-speed, jostling horribly, approaching the rather broad gap between staircases with no signs of slowing or stopping. Ferreole cackled, wielding the halberd as though perhaps he intended to pole vault the gap if the car didn't make it. "Hold tight!"

For character reference purposes—the Ford has only been physically inside Hogwarts long enough to zoom up one staircase and down this one, leaving only shrill portraits and maybe one tiny tire skid mark in its wake. It's total time inside the building will be less than three minutes, witnessed only by Cain, Ferreole, and some seriously unhappy portraits and suits of armor. Rumors are free to generate, of course!

Cain had been minding his own business when the chaos had begun. Deposited neatly onto the car, he'd had no time to think before some kind of crazy animal had swooped towards him, instead using the broom Ferreole had shoved at him to knock it away, and then hit it properly when it came back towards him. There hadn't even been time to calm down when he'd realised he was sitting on top of a car, with his headmaster waving something which looked dangerous around at head height.

Ducking the archaic weapon- whatever it might be- that Ferreole was wielding with considerably more enthusiasm than regard to Cain's safety, he'd latched onto some kind of ridge thing that seemed like a better handhold than the smooth metal he was perched on. The approaching gap filled Cain with a sense of doom. He'd thought that the car had been going too fast, but suddenly it wasn't fast enough. Just before the stairs ran out, the car put on a final burst of speed, Cain almost- almost- yelling in fear as the car's momentum carried it across the gap.

The car bounced painfully before whizzing down the staircase, Cain clutching on for dear life, broom tucked under one arm while he tryied to look over his shoulder at where the car was headed. One wheel hung in midair as it skidded round a corner, but it righted itself and raced out of the main doorway, pursued by the indignant shouts of the paintings.

"Sir, can you steer this?" Cain half- yelled as the car bounced down the staircase, not expecting the answer to be yes. The car seemed to have a mind of its own- which was possible, but made him worry about his chances of surviving the next minute or so of his life. It rocketed out of the building, clearing the first two steps before thundering down the last two, its random path leaving Cain in no doubt that it was headed for the Forbidden Forest. Now on flat ground, it picked up speed as it carried its passengers into the Forbidden Forest.

The uneven ground made it difficult to stay on the car, and Cain wasn't quite sure how he managed it, let alone Ferreole,  and when it finally slowed to a reasonable speed, he slid off, stumbling as he hit the ground but managing to stay upright. He turned to see if Ferreole was alright- although he suspected that if Ferreole put his mind to it, he could survive the apocalypse relatively unscathed. Maybe it was something about looking old. He seemed fine, though- not nearly concerned enough for someone who had just entrusted his life to a deranged car.

"What just happened?" Cain asked, frowning in confusion, "Sir."
