They come from nothing. They are madness. They destroy, corrupt, and their roots sink deep into any unfortunate world they come across. Cosmic parasites. Entropy made flesh. These gods are not your gods.
These gods are the Old Gods.
The lords of the void
In the cosmos there are certain forces at play. Two of the most primordial are those of Light and Shadow. Light emanates, it illuminates throughout all existence, and by its radiance we see all existence. It is the revelation, an evanescent force that brings other forces into existence. And such light inherently casts a Shadow.
Dwelling within that Shadow are beings of pure Void, the remnants of before existence itself. These beings do not exist as we understand it: they are a rejection of existence. They cannot exist, in the way we think of it. They are the Void Lords, dwellers in the bastion of Shadow, the last redoubt of the darkness that preceded Light. And they hate existence, the mockery of it, how it creates distinctions and boundaries and things. They hate all things, all life, all Light. They would see it all end.
