Creating spells! Carl was excited for this. He listened to Professor Marchand's explanation, took notes, and when they were (finally) allowed to try out incantations, he put down his quill and read through his notes. Hmmm. He could see some possible combinations, like "to cut" "wood", "to bind" "paper/parchment", "to cut" "paper/parchment" and so on.

The Hufflepuff took out his wand and decided to try out the latter. "Lacero Biblus!" He said as he aimed his wand at a spare piece of parchment. It did not work. He looked around the classroom, uncertain as to whether he was doing it correctly. He saw a Gryffindor asking questions - lots of them - and paused his work to listen to the Professor's reply.
