This situation (as is so often the case in Taldor) is only going to look even more and more complicated as Carissa Sevar investigates it further.
...possibly a lot of the problem here is that Sevarism in Taldor does not have a clear agenda that lines up with anybody's personal incentives? In Vudra, at least, there was something of a map onto Lawful Evil Irorism and there being a place for those people to go that wasn't Asmodean Hell, and a daily activity of self-refinement that the monks there could readily recognize. In Taldor, the closest thing to a clear agenda that makes sense in terms of anybody's direct goals is Iomedaen Sevarism, which doesn't want anybody in Hell in the first place, and therefore would like Carissa Sevar to conquer a country as soon as possible.
What does Carissa Sevar think her followers in Taldor are supposed to do? People will ask her this question with the air of somebody who never thinks to question, for a fraction of a section, that Carissa Sevar must have built this whole cult for herself on purpose and had some purpose in mind for it.
