Plague Gardens and skull mountains are neat but I feel they are focused on too much. The Xur are a good example their theology imo focuses too much on getting snatched up to Khornate heaven.
I've always liked this fluff from the 4th edition CSM codex
>The Chaos Space Marines abhor the thought of a half-life locked away inside the imprisoning womb of a Dreadnought, where they can no longer see battle with their own eyes or feel the kick of a bolter in their fist..better to die and find final release in the surging maelstrom of the warp.
I think I prefer the treatment in pic related or the Conan quote I posted rather than chaos worshiping barbarians having the full skinny on the chaos gods and their realm in the warp aside from them having a different name like Baptur or Flibfamble.
