I'm sure that Pentan shamans worship Yelm as a Great Spirit, and not as
Rune Priests (TM). Based on common sense, as well as past conversations
with Greg re: Sheng.
If the "merged cults" theory has legs, why do the Seven Mothers have only
two Rune levels and not (five or six or) seven? Or do *any* number of
merges produce two Rune ranks?
