So I was reading the IKRPG book the other day (like I do) and noticed something interesting in the section describing the different peoples of the IK. When discussing the human communities that live on the fringes of civilization and do not worship the normal gods, it was mentioned that these communities still practiced totem worship. Specifically they mentioned wolf, bear, and raven totems. IMO, this passage refers to the peoples that remain allies to the Circle Orboros and make up the ranks of the Wolves of Orboros (wolf totem) as well as ancient allies of the Old Witch of Khador (Raven totem).
But what of the Bear? Are these people separate from the Circle, or does this allude to possible future additions to the Circle's allies/available units in Hordes? Wild speculation: is this the heavy cavalry that we will be getting soon?
This would be interesting. But I'm not sure how well Circle would integrate.
You have the Tharn, ravenous and wild. Then the attitude of Circle itself- civilization must die.
Between the two of them, I think you'd end up with xenophobic characters who are completely technologically illiterate. And they'd know next to nothing about the outside world and it's peoples.
It'd be kinda like Third Rock From The Sun, first season. Where the aliens just don't understand what's going on and bumble around, make asses of themselves and insult everyone.
You could still have savages, but I guess you'd need to keep way from either extreme.
