The Goremont Grim (new introduction)

The Goremont Grim is an ancient portal between dimensions, universes, and planes. In the beginning, when the first split of reality occurred, the Grim facilitated travel between the two new realities. When reality split again, the Grim expanded, and at each successive split the Grim exponentially grew larger and more complex. After millennia, the Grim itself became a reality of its own: the reality with links to all of the other dimensions.

As travelers walked the Grim Path their consciousness imprinted upon the new reality. The travellers’ multitudinous concepts of the underworld, of nightmares, and of dungeons stayed behind and expanded the Grim. It is these ideas that twisted the passages of the Grim from the straight and direct ways is bore for millennia into the never-ending maze that is the Goremont Grim today. Without the Walkers, the Grim would be staid, safe, boring.

After the twisting, the Grim itself gained sentience (of a sorts) and educated itself upon the consciousness of those what walked within.  It can now plan, think, create and is worshiped as a god in hundreds of worlds.

The goal of the Grim, or even if it has one, is unknown. Some speculate that it now seeks dominion over the multiverse, others that it merely seeks death from a senseless and eternal existence.
