As the cataclysm tore through the Earth, something happened that even the Anu did not know was possible.
The powerful explosion, originating from advanced Anu technology that had never before used been for this purpose, fractured the Earth and split her apart.
It created five different worlds, occupying the same space, but phase shifted slightly in such a way that they cannot connect. It was at this time that entire cities, even entire continents, disappeared from the world as we now know it, although stories of them remain.
At the same time, two slivers were shifted away, one a place that is only darkness, the other a fragmented place.
