Here’s another good question – what are the most popular cults in the Lunar Heartlands?
The answer is the Seven Mothers, either collectively or individually. About 24% of the population in the Heartlands belong to the cult. All of the other Lunar cults total about 10% of the population. So a little more than a third of the population in the Heartlands belong to Lunar cults (we are talking more than the minimal lay member rites).The next biggest cult in the Heartlands is Lodril at about 14%. In third is the Grain Goddess Oria at about 10%.
So where is Yelm, you might ask? The Yelm cult is very magically, socially, and politically important, but it is comparatively small numbering about 4% of the population.
And Shargash and Polaris are each no more than about 2%.
And again, Tarsh resembles the Lunar Heartlands in that about 25% of the population follow the Seven Mothers and 10% follow Hon-eel. Where it gets VERY different is the rest of the population largely follow Lightbringer gods and their associates.
