  Summary

  In the world of Warhammer 40k, there is the Emperor of Mankind, guardian of humanity, and the Chaos Gods, entities that seek the destruction and enslavement of all life.
  But what if those roles were swapped? What if the Emperor wanted to dominate the galaxy, and the Chaos Gods wanted to take care of it?
  The story of the Imperiac Heresy and the Horus Rebellion searches to explore that very thing...

  Summary

  BEHOLD! Stage 2 of the Imperiac Heresy! The short stories! All of various sizes, contents, and ideas! There will be many ideas introduced, and many shatterings of what is canon!
  So hold on to your butts! For this is about to be a wild ride!

  Once again: Please recognize that this is a fanficition, an AU, and a very much on crack universe. I CAN and WILL be taking canon, looking at it, laughing in its face, and proceed to beat it to a pulp. Oh and feed it to the sharks.
  ANYWAYS!
  What I am getting at is, there is probably going to be things some of you LORE purists and whatnot will not like.
  You don't like it? Then don't read it. Don't comment, don't anything. Just leave it alone.
