Haha, sorry. (Woman.)

It's about three Blood Camps (I haven't figured out the names yet). 
The first camp's for those with elemental powers, the second's for half-breeds (half-human, half-creature), and the third's for normal children. (Yeah, kinda racist) All camps aim to train children from 8 to 18 years old to protect themselves and the world from Mythical Creatures that have come back after roughly 800 years because of an amulet (I'll explain that later, it's not that important anyway). 
The camp trains these children for 6 months a year until they get past the age limit (18) because by then, they'd have learned how to handle at least the most basic weapons and skills.

Does this brief explanation cover it?
