Through the gap

As I looked through the gap in the tent, I saw the creature. It was devouring my companions terror-wrecked body, its mouth dripping with the sickly mixture of crimson blood and warped saliva. It oozed thick clumps of mucus into a congealing puddle on the sodden, muddy floor. The rain poured down as hard as stones and only the lightning highlighted the creature.

I said that I saw the creature, but this isn’t correct. I only saw it by its absence, a surface that did not reflect light, but radiated pure darkness.
It was a daemon of night, a creature not born of nature. It was not from our realm of material and substance, but of the ‘other side’, the immaterial dimension of souls, a shifting black void of meaningless, horror and chaos. This daemon of the night prays on the living, for its whole perpose and existence is to destroy life, to dine on the flesh and souls of life.
Humans created these abominations of darkness through their thoughts of evil and perversity. They are twisted insanity and death given form. They are the opposite of life in every sence and they will stop at nothing until the accomplished their mindless goal, with the universe bleeding at their feet.
I know this because I have seen into the Warp, I know the secrets that it holds and I know that it is impossible to win. For you cannot destroy nightmares.
