First Idea- Probabilis Academy.
Ever since thousands of years ago, some humans have discovered how to manipulate their surroundings, and use an invisible energy to do things. At first, these humans were worshipped as gods(and demons), but realized they weren't, for they could die. As the numbers of these special people, called magi, increased, many villages gathered them for many purposes, mainly for war. These villages grew into kingdoms and empires, and they used the mages as weapons of war. Hundreds of years later, only 12 empires stood, as the rest have fallen. Each of these empires had a specialty. They arePyra, Hidrak, Oeg, Dniw, Cyrek, Gynere, Rumina, Radk, Leah, Shi, Oivd and Uni. After hundreds of years of a stalemate, the empires decided to make a peace treaty.
Every 10 years, Magi who think they are up to the challenge fight eachother in the Probabilis Arena, located in an island far from the main continent, and the winner brings fame and glory not ony to themselves, but to their empire as well. To reinforce this, they made an elite mage school nearby the arena. This school would teach the young magi-in-training that have the potential to become great. You are a new student, who is going to attend this school, whether from scholarship or bribery, and learn the ways of the art.
That's all for now!
