This castle needed a map. Ludwig had decided that after he'd set off to find the library on his first day and, a half-hour later, had managed to find a closet full of melted cauldrons, the school's trophy room, and a multitude of disused classrooms, one of which was being torn up by a ghost who had beaned him on the forehead with a broken bit of chair. He wasn't even that bad at following directions, honestly! The castle was just frustratingly huge, and seemed to be constantly changing. Passageways led someplace different, staircases vanished... nothing as weirdly spontaneous had happened at his school in Germany, Ludwig could recall.
The older Slytherins had assured him that he'd get used to the castle eventually, but Ludwig had decided he couldn't wait for that luxury. He didn't even know if he'd be allowed to stay on the following year. So, he'd set aside a portion of his free time to make a decent map for himself. Two afternoons so far, he'd walked the halls, tracing lines onto a large sheet of parchment and taking notes on any peculiarities the doors or staircases held. It was a daunting task, Ludwig quickly realized: he'd had to go back to the same places twice already, just to make sure this staircase or that door didn't open to the outside on odd-numbered days or something equally as ridiculous.
Today, according to Ludwig's notes, he had just finished checking all the doors in the east-west hallway of the fourth floor. Holding a pot of ink in his left hand, his quill in his right, and the parchment spread out between them, Ludwig squinted at his notes and frowned. He still had to the north-south hallway, and it was getting late. But he wouldn't have this chance again, and he needed this map to be perfect - or at the very least, reliably accurate. Picking up his pace a little, Ludwig rounded a corner just in time to slam into someone walking the opposite direction.
A ripping noise, the shattering of glass, and Ludwig stumbled and lost his balance, picking himself up from the floor almost instantly as ink seeped into his robes. His map had been torn in two, but what was of more interest was the person he'd crashed into. The brunette was lying on the floor, and the black robes he wore had yellow accents. Picking up the pieces of parchment, Ludwig walked over to the other student, "Are you alright?"
