Warrior (book one of Kefale Academy series)

Welcome to Allysia. An alternate world to Earth, with some excitingly strange powers. Our human myths rain from there, and the world is home to demons. But there are a people there, the ones we hailed as gods thousands of years ago. The people of Fire, Earth, Air, Soul, Water, and Life. There are 7 Academies, one for each continent. The 7th reigns in the continent of Demons, where people from all over Allysia congregate and learn to hunt demons, becoming Kefale Knights. The Mighty Ones. However, there was once a people that lived there, and not the demons. They left when the demons invaded. So, where'd they go? And what became of these people?
