One Tuatha De Dannan camp has to be in Ireland, because there's a geis that makes its holder return to Ireland at regular intervals.
The Aesir camp would probably be in one of the more inhospitable regions of Russia, because nothing says "Viking hardass" like training in the bitter cold with little food.
Mura: -flips the bird to veterinary science with one hand and Euclidean geometry with the other-Maybe also a safehouse/equipment depot located in Hell's Kitchen. (I've been working my through Garth Ennis' run on The Punisher).
Minnesota's also appropriate. (A little sports reference there).
Plus, the children of Ares might gain additional training at a facility near Michigan State University.*.
Embroiled in slave rebellion, I escaped crucifixion simply by declaring 'I am Vito', everyone else apparently being called 'Spartacus'.The Egyptians should be in southern Illinois (called Little Egypt), the Loa just outside New Orleans or in Haiti, the Chinese in California, the Aztec in Mexico, and the Japanese in Hawaii or California. They could be the local branches of the Parthenon, with each having an additional one in their homeland.

So, my crew and I are gonna try out the game Scion in a couple of weeks. One idea we thought of incorporating as part of our Scion-verse is the idea of "training camps" for the heroes. There's no required lessons, or age limits ('cause some half-bloods are "late bloomers", so to speak). Basically, it's half military school, half Xavier Academy. How long they attend depends on how quickly they pick up on their godly abilities (usually 1-2 years).
This element isn't gonna be a major plot point, just one element. The thing is, we're having difficulty deciding where the schools (divided by pantheon) will be located. One player suggested that the one for the Dodekatheon be located in Long Island, as a Percy Jackson reference, but we're all blanking on the other pantheon camps. Suggestions? (NOTE: The game probably won't be limited to America, so the camps [or even multiple camps] could be scattered across the globe).
