I approve.
I've always been a very big fan of the Outcasts' religious aspect, but until now, everyone has really downplayed it. The inclusion of the vanilla-contrary idea that the Outcasts worship the Nomads has also not helped this...
I did, a few months ago, roleplay an Outcast known only as Padre... His story was quite different, and he was perhaps more radical than the KoSJ, but it was definitely on the same lines. This genre of Outcast roleplay is the only I've ever explored in Discovery. I really loved the Outcasts in Vanilla, but now I don't really like them...
I'm delighted to see an Outcast group actually basing t itself off of the Catholic aspect of the Outcast culture. I'm also glad to see that you don't put much stock in the whole silly Nomad story. Hopefully you can be a force to take the Nomad-nonaggression-clause off the Outcast ID.
And, about the document itself - looks good. It's simple, makes sense, and tells me what I need to know. I think you guys will go far.
Good luck!
P.S. I might, well, be interested in joining, though I have very little time to spread around.
