Magic is real. 

Mother Nature created humans with a magical seed inside them. the seed will blossom as they grow older. However, there are some people whose greed took over them. They are called hunters and they use their powers as dangerous weapons. They even created monsters that could off the magic in the mages. Without the magic seed, Mages will die. 

Upon knowing this, Mother Nature immediately stopped all growth of the magic seeds in babies, young children and teenagers, so there are lesser mages in the world to be hunted. Mother even created another species of humans that have no magial seeds in them. 

mother collected the remaining mages in the world to protect them and they hid unter a magical tree stump that leds to a large house.

Some of the mages have children with each other and the number of Mages began to repopulate. They prepared to have a war with the hunters and tried to gather as much children whose seeds are still ungrown to fight the hunters by training them.
