What is the purpose of the caves that dwell within Jade Mountain in the novel, Moon Rising?

The Jade Mountain Academy is made up of a series of caves inside Jade Mountain. Each of the caves serves a specific purpose. For example, the prey center is the “cafeteria” where the dragons gather to eat. On the first day, there is a lot of live prey running around but the teachers discover this is too chaotic and they change the process in the coming days. There is a music room that Moon loves beause the loud noise blanks out the chaos of thoughts from the other dragons. There is an art room, a history room, sleeping rooms, and a room for injured dragons. There is also a cave with a pool.
