A few hundred years ago, when Europe was conquering the new discovered and thus foreign lands, many tribes, native to the "New World", were often confronted with misery such as war, disease, rape or explotation. Many turned to their gods in despair but the gods never answered and so they were abandoned.
Only few held on to their holy creators, waiting for help with nothing left except their mere life but in a world not worth living in. And only one tribes prayers seem to have been heard. The tribe's gods lived in the nightsky shining bright as stars and watching over their people on earth. They witnessed the destruction of their creation and thus took their turn. One night , the prayer's melody quieter than ever, creatures emerged from the darkness between the stars being just as dark as the space they came from. Black, scaled, with hornes on their heads, but thin and weak. The tribe's elders fed the creatures with their sould which gave them the strength so that they grew within seconds and gained great muscles all over their bodies. Once they were strong enough they raided the camps of the conquerers killing everyone who was too slow or too dumb to run away. The tribe called each one of the creatures a "Grima", a savior. They shouted the word over and over until the nearby camps were all full of dead bodies and empty of souls and the Grima's hunger remained. Confuesed and in fear the tribe's peope realized that the Grima weren't what they seemed to be. Ans the few who survived they hunger called them "Grimataur", a false savior.
The Grimataur's hunger was unsatiableand so its slaughter continued.

Eventually mankind did what it mostly does; it developed so far that they were the ones to hunt the Grimataur. And they were successfull, killed many, hurt many. A few survived in the shadows and were smart enough to keep hiding themselfs. With time passing by the Grimataur vanished from peoples minds and at most turned to a myth alongside the vampires and werewolfs and similar.

Today it's only the old and crazy people who lock the doors and windows from their small houses outside the cities. The Grimataur has roamed the solitary places where only few and defendless humans live. But the cities nowadays are chaotic, confusing and full of people not seeing or believing anything while busy and hastly rishing through the streets and buildings in their grey world. They don't realize that they are the perfect soul-buffet attracting the Grimataur and due to their blindness giving it the ideal chance to make his return.
