Teacher

Princess Zelda's Teacher is a character in Spirit Tracks. He is first seen at Link's initiation ceremony for becoming a Royal Engineer, and is the one who takes Link and Alfonzo back to the castle after Chancellor Cole attacked them. Though he scoffs at Link for suggesting that Princess Zelda has been kidnapped, turned into a ghost, and that she is right there next to him, he does worry that she has been "playing outside" for too long, and resolves to track her down. He is actually the only character in the castle who even believes that Zelda has left.

Eventually, Zelda's Teacher dons a meager disguise and goes to the Hyrule Castle station to ask to be chauffeured to a random station. From then on, he will appear each day at a random station, and ask to be taken to another station. If successfully chauffeured, he will reward Link with a certain amount of Rupees, depending on how well Link drove the train.
