The ticket price of the flying ship was calculated on a per person basis.
It wasn't really expensive, but neither was it cheap. Two hundred magic crystals for every passenger.
This basically made it impossible for ordinary peasants and low-level apprentices to ever take a ride on the flying ship!
Leon would never receive more than ten magic crystals per month back when he was an apprentice Mage. If one deducted the basic cost of borrowing books, renting the lab, and purchasing magical materials from his income, he would barely have any crystals left at the end of each month.
And if he wanted to increase his income? The only way would be to take on the apprentice missions put out by the Mage's Association.
