Welcome to Camp Dublin! It's a lot different from Greek, Roman, and Egyptian. Here, kids are chosen from they're god parent and come to camp so they'll be safe from the monsters and learn to use they're powers.
Camp Dublin is a big island located not too far from the Republic of Ireland. Many Irish people build the camp for kids who are, some what, "special" and "gifted". Only those who are chosen by the gods are permitted inside the camp. The citizens of Ireland, many years ago, build the camp as an altar to the gods, but as it turns out, it was camp.
