So as the Title states I am looking for help developing background. I am building a story around several battles against Chaos I have now. But part of my issue, I need to build a better picture of the enemy of my main guys to properly build out the story.  Here is what the Chaos Faction would consist of so far: Chaos Undivided Knights - Khorne Ravenger with Tzeetch and Slannesh Armigers (no Nurgle yet.) Iron Warriors Outpost with several Warmachines Word Bearers Possessed and Raptors.
