The Academy used its own currency, YP (Year Points), for all transactions, so there was no problem in continuing using it for the new areas.
Over time, more small quarters and districts took form, with their own set of guidelines to follow.
Of course, the situation remained the same, that is, only students, professors and staff of the Academy could visit these places.
That meant that not even one person on the Academy premises was unaffiliated with the Academy, even if it was just a cook or waiter.
Well, they too needed staff anyway, making it all the more self-sustainable as even some students did odd jobs due to a lack of YP.
How they had done it, so many people still could not fathom, but one thing was completely and irrefutably certain in everyone's mind.
All of the Academy's prestige and self sustainability had only been possible because of one person.
