Wizard Academy (Countryhumans AU) (Amazingly slow updates)

Author is away, please check announcements.
-------------
This is a fantasy AU where all the Wizards and Hollows live in a world named Etipora. There is one special wizard academy named Zogine in the mysterious kingdom named Orudora, for the 'chosen' students.

Everyone wants to go but only 1/5 of the world's students can go. No one knows what is after the kingdom's fog shield that protects it from the outside world, those who return to their kingdoms never reveal the secret as a promise they have to make to keep the kingdom safe from those that are a threat.

One day, a forbidden spell that was cast caused havoc inside the academy before reaching the outer world. The Hollows blamed the Wizards and started to hate them, but it wasn't the wizards' fault, they knew that something was up. No one could have done it, right? Now it's up to them to find the culprit, restore peace between the outer world and the magic world but with newly formed Obsidian sprites, it won't be an easy mission.

P.S. Not Geography and Historically accurate. Also, there is no country x country in this book, you can ship the characters in the book I just won't be writing any romance in it.
