While working on one of my armies and thinking about how Ken co-opted the Orks from Warhammer into the Brootalz, I was doing a similar thing with one of my armies that's supposed to be "the Chaos" of Brikwars.
Upon starting a discussion about it, Some others like Bookwyrm mentioned how it relates to the 4 horsemen of the Brikopalypse. Peace, Justice, Stability and Poop.
Of course in a world that's all about war, the concept of peace and such is treated as a bad thing, but in-world, most people don't make armies that act like the VOL, Immortals or Brootalz, that just attack everything and everyone, we had 5-10 years of pretend space UN with people making alliances and doing peacetime soaps and the sort.
While looking at the 4 horsemen, We talked about changing the horsemen up a little and creating a "Dichotimy" of the brikverse, Identifying some of the fundemental concepts that people explore and often are at odds over.
We picked a number of "traits" that we would associate with each mentality or side, and arranged them in a way that it was layered, it wouldn't just be Peace vs War. but Peace and Friendship vs War and Angst, etc. groups in the brikverse don't have to be all of one category to "take a side".... and they don't even have to take a side at all. But some that do, do so in the extreme to the point that it is unusual, like the Brootalz being warlike, or the Polish trying to be peaceful, etc.
also. We wanted to in essence, create 4 "Chaos Gods" to be the foils to the 4 Horsemen. at this point we are abandoning any sense of good vs bad. Both sides of the fence have good and bad things about them, the words are purely subjective.
it should also be mentioned that for the most part, horsemen, gods, etc. don't actually exist, they are Ideas, more so than that they are deities, avatars, etc. (but we did explicitly try to create Khorne, Nurgle, Slaanesh and Tzneetch equivalents when thinking of the traits for the chaotic side)
at this point this is still just a work in progress, but I wanted to post this in length to get people's opinions
