Professor McAiken opens the door to the Transfiguration classroom. He hopes the students will enjoy the lesson today. He began to prepare the room. One the long side tables McAiken began to place the subjects for the lesson. On the first table went the non-living things, then on the second he stacked cages, and aquariums. At the head of room he placed a basket and a box. He went over in his mind exactly how the class would go. He finally had every set he took his seat and began to wait.
