The Fall of Moldar- Orc Campaign
The Material Plane is the realm of physical, corporeal existence. It is a vast realm, but mostly empty, filled with a void of space-dust and lit by thousands of what mortals call 'stars'. While the fire-orbs are indeed bright, they pale in comparison to the three great suns, around which orbit the many inhabited, vibrant worlds of the Plane. Unknown even to the gods, this realm was not always in existence. The beginnings of this realm lie with the great Outer God, Azathoth. Azathoth dreams, and this dream created the Material Plane where nothing existed beforehand.
While Azathoth remains dreaming, the Material Plane exists. When he wakes, if such mortal terms as 'waking' and 'dreaming' can apply to a being like it, physical existence will end.
