the enemy

I've been procrastinating a bit on writing stuff for road game because I don't really know how I want the ending to go. I'm struggling with the antagonist and what it's really supposed to be and do; what its powers are, what its goals are, etc. Is it something out of the cthulhu mythos? is it just sort of a generic "spoopy monster" from the cosmos that wants to eat people? Is it a dream monster, a demon, or something else? 

I don't want to be super obvious about this in the game itself, but I want to have some of this spelled out at a meta level. I think it is something that is "summoned" or "awakened" by the exercise of power for ostensibly "good" reasons. (I think that's one of the main themes that gets into this game: sort of a "road to hell paved by good intentions" motif.) So in the first episode, the "cult" are exercising "god's law" but they're ending up with something that is gonna summon $monster eventually. And the village in the fog is a group who already did. 

But the monster himself.. is he a will to power monster? is he the abyss? is he the ghost of hitler? He devours and always wants more (power / control / souls ownership). He is an antichrist - an? the?
