GW The Rift

Before there were humans or dwarves, before there were even worlds or the stars that light the night sky, there was but one thing in the universe—the Mists. The Mists touch all things. They are what bind the universe together, past present, and future. They are the source of all good and evil, of all matter and knowledge. It is said that all forms of life, no matter how simple or complex, can trace their origins back to this one place.

In the middle of the Mists is a spot where time moves neither forward nor back. It is a tear in the fabric of the cosmos, the point of perfect balance between all forces of the universe. This place is known as the Rift, and there is nothing to which it does not connect, nothing that cannot be reached from inside it. Those who have the know-how to travel across the universe through the Mists must pass through the Rift on their way to all other places. It is the centre of all things.
