It's the essence flame, and it's coming from the depths of your heart. The flame will burn you to death, says the elder of the tower. He's worried that the newcomers are going to burn themselves to death from the flame, so he tells them to circulate the flame to protect their heart. He also tells them that the tower elder is nearby. The elder tells him to hurry and save the guy, because he's going to be a star in a few days. He tells the elder to help him register for the sixth floor, where he'll be able to train with the other students. He says that the place is so strange that he can't even stand it. He promises to bring the elder around and show him around.
