They undoubtedly lived at the same time, but the Incans and Mayans seemed to be quite a bit further along. And given their location one would have to assume they interacted at some point. If so, what was it like, peaceful? Conflicts? also I understand that they probably had the same or very similar origins, in that case did they know about eachother? Like we had a faction go north 100 years or so ago and they haven't came back.
