I know very little about North American/First Nations faiths, beyond little bits that have made their way into general American knowledge. What is clear about the AD&D material, though, is that it is an amalgamation of different cultural traditions, primarily Navajo and Plains/North Eastern faiths as far as I can tell. As such it may be more appropriate to split up to better represent the actual faiths and be more respectful towards the individual cultures. I’d need to know a lot more about the various beliefs here to work on them, however.
