Nighthaven

Philosophers believe that Nighthaven is simply a network of tunnels and caverns that extend beneath the crust of the world and possibly further. No one has ventured deep enough into the realm to find out because of the many perils present. Some researchers send expeditions down to map sections of the terrain, but never without heavy guard. Those who stumble in by accident rarely get out alive.

In reality, Nighthaven is an anchored demiplane that occurred early in the formation of Saratta. Like Saratta, Nighthaven was formed out of raw abyssal material taken by the gods to form the world. As the material came in contact with the Mithian Slip it gained the capacity to become Plane; the still cooling magma transforming into a crag covered mass with snaking tunnels. Holding a relative shape to their world, the gods chose to encase the small plane within the world. Lifestitcher's were used by the gods to tie the plane into the living world, blending its planar properties with Saratta.
