Halfblood Academy

A school where demigods learn about the 'mythology' world, Percy plus co, and much more! They train to save the world someday. After 5 years (starting at age 10 earliest and age 13 latest) they graduate and go to the camps to train harder and possibly go on quests. Once they are old enough they can go to halfblood city (like new rome kind of). The new demigods face hardships, crushes, bullies, and the Heroes of Olympus and maybe even their legacies.
