One of the more beloved minor cultures among many players are the Aeolians – sorcery-using Orlanthi or Orlanth-worshiping Malkioni that live in the south of Heortland. Now it is worth keeping in mind that there are somewhere around 50k Aeolians in total, maybe more, maybe less. That puts the total number of Aeolians at around the size of five Sartarite tribes.
Now that puts some big limitations on them – the other is that they are in contact with the God Forgot “atheists”, who also number about 50k. These two are separate communities and religions, even if they are often conflated together by other Kethaelans.
If we assume that less than 5% of the adult population have learned sorcery, there might be 1500 people with sorcery skills among the Aeolians. For comparison, there might be 1000 Lhankor Mhy initiates with some sorcery skills in all of Sartar. But Nochet might have twice that many Lhankor Mhy initiates that know sorcery, probably more.
Lots of the HeroQuest Voices entries are not “canon,” (just compare them with what is in the Guide) and I do not really want to spend the time editing them right now.
I tend to think of the Aeolians as being roughly analogous to the Druze or Yazidi. They are an ethnoreligious group that are always a minority outside of their strongholds.
As an aside, I do not believe that the Aeolians try to convert anyone. I am not sure they even accept converts!
