Quill landed gently and walked into his house. His parents' house, actually. They weren't home at the moment, too busy. He walked to a room and looked into his bag. Inside, there were a few bits, a book, a quill, some parchment, and finally a sandwich packed in a blue box. Sometimes he got hungry while on the train, and he packed the sandwich for that purpose.
He put a blanket in the bag, just in case he somehow needed it, and flew back to where he had been, carrying the backpack on his back.
