Between

The planes of existence are like individual pockets of order within a vast universe. That space which lay between each plane is referred to by scholars of the planes as the 'Between'. Little is known from it as few who find themselves there ever return. What is known of it is that it contains large amounts of raw magical energy. Those that believe in the idea of Creator Gods also believe that this is where they originated from, and that they used the raw power in the Between to shape each of the planes of existence.
