The Two Cities
Two thousand years ago the planes aligned the barriers between the worlds thinned and the world began a decent into chaos as the Far Realm overlapped with the world that is. With the help of the gods the civilized races built three great fortified Cities to contain the lucky few chosen. Eladrin (Ancient Elves), Dwarves, Halflings, and Humans living together sealed away form the death and destruction of a world gone mad.
This project is in the early planning stages and will likely be using the new Pathfinder 3.5ish system.
