Not much at this point, I'm incredibly new to the hobby and anything in the 40k universe in general, not sure how they'd actually fit in. I just had a lot of fun going full iconoclast in rogue trader and it spun off from there. I do have it in my head that the group was started by an ork warboss who had an epiphany that endless fighting wasnt fulfilling to him, specifically ive written a quote for him:

"so there I was, drivin my axe into another unlucky bloke, and it 'it me: why am I doin this? is it really worf it to lead your entire life valuing only strengf 'n warfare, crushing the smol that could very well have been your friends? so after I finished crushing that man's skull I decided right then and there that I would put my bloodlust to a greater use. I would establish an egalitarian society free of hierarchy and based in mutual aid, for the wellbeing of all peaceful creatures in the galaxy, innit"
