Originally we were talking on Space Battles in A Familiar Setting, about Saya no Uta, and I've been meaning to write a good Eldritch Abomination story for a bit. This is technically a crossover between HP Lovecraft and the Familiar of Zero. I hope you guys will enjoy this. There are some mistakes in it.Introduction
It floated through the formless, limitless expanse of dark between galaxies. Always asleep, never awake. Floating since time immemorial. Floating and dreaming. But what could something like this dream about? It's impossible to say. For how could we Humans ever hope to understand it.
If fate was kind it would have stayed sleeping and dreaming until the end of the universe. And yet fate wasn't kind. It would be awaken by the plea of a young girl. A girl that pleaded for a familiar. And for the first time since it had fallen asleep it awoke. Time seemed to giving a glass shattering shriek, space began to warp, the laws of physics were inverse and then torn asunder, stars went super nova, and the entire universe shuddered in fear as a darkening shadow was cast across it.
From the formless writhing and twisting mass that made up its body, its eyes opened. And the very fabric of reality came crashing down. Everything was reduced to a swirling mass of chaos for the laws of the universe couldn't comprehend what it was. It could have ignored the plea, gone off into the universe continuing its hunt for the lesser beings that were like it, eating until it could finally devour the blind idiot god; the abyssal idiot; Azathoth. It could have fed on the nightmare of species.
And yet it chose to ignore that, ignore it all. For the plea of the young girl had reached it. Who would be foolish to try and summon something like it, the hunter of the Outer Gods. It awoke to her plea, and it would answer her summons.
Tearing through the barriers of the universe, it traveled to the location of the voice. To met the one who had awoken it. The one named Louise Vallière.
