The prophet's dream

A few of the more powerful gods from all four of the magical world decide that the worlds have become too involved with each other and so they use their powers to alter the world, dividing up up the U.S. between the Norse, Egyptians, Greeks, and Romans and wipe the memories of everyone. The result was four major kingdoms known as the Roman Empire, The Greek States, the Egyptian Empire, and the Norse Alliance. Now in a medieval state, the new world is formed, but the gods did not succeed in completely wiping everyone memories. What will happen when a prophet starts to remember the old world.
