We don't have much more common ground than that with the Tuchux. They're barbarians, we're not. For background, Shaitan was in Dagorhir when I joined. The Tuchux number about 80 active fighters nationally. They're arranged in groups of ten the way we are in our Legions of five.
Shaitan is a commander of one such group of ten.
I've spoken with him at length about the kind of arrangements we might make to fight with them at Pennsic. Romans can't be Tuchux any more than Tuchux can be Romans. They feel just as we do about their people conforming to their established standard. They feel the same way about their standards as we do about ours, and properly so. The arrangement we arrived at is that Rome will camp near and fight with the Tuchux.
