We do see quite a lot of them. Poorly clothed and labouring with heavy loads around the Fort. We also know they tend to kill them quite often in the 'arena' even though they know that the slaves don't put up much of a fight. I also feel fairly sure that Boone killing his wife rather than let the Legion own her as a slave kinda seals the deal for me. Doesn't Caesar himself call the Legion, 'Nomads' or something similar? I'm not too sure that any 'Legion civilisation' actually exists?
Yeah, we see a few slaves in their military camps, but I don't really feel that's enough. Although slaves are indeed treated as the lowest of the low.
Their is some kind of Legion civilization, they have a capital in Arizona (Flagstaff) and they have 4 U.S. states.
Yup they needed some brain surgery and i can dish it out.
Lol RP.
