Tremaine was not satisfied with the explanation and shook the sphere again, listening to the chimes. "But how does the magic work, Uncle Ari?"

Arisilde smiled. "It's very simple. When you talk to it just right, sphere knows what you want to do. Then it talks to the ether and tells it how to do just that!"

Tremaine still looked dubious. "How do you talk to it right?"

"If you want to do a spell, you have to talk to it with your own magic. But you should talk to it anyway, or it might get very lonely and sad."
