"Hi! I'm Aang! Where'd the ocean go?" The strange boy looked around, seemingly searching for something, however, his words made no sense to the class.
"Is he a peasant?" The red haired girl scrutinized the boy's outfit.
Professor Colbert studied the scene before him. "Perhaps not, Kirche. It is apparent to me that the boy came in response to the familiar summons. However, why did the creature come as well? It may be the boy's own familiar."
