I’m thinking about Ovarianism, and potentially having it that one of the big dividing differences between branches is the view if the afterlife.
The faith originally started as reincarnation based, about all souls transitioning from one body to the next in a birth/rebirth cycle. Early on due to intermingling with neighbouring religions they picked up concepts of a “land of the dead”and eventually bled into the creation of an actual “afterlife”
The (numerous) text itself is contradictory on the nature of the afterlife, but the general consensus usually view paradise as either a “rebirth” in bodily form or the eventual breaking of a “cycle”. Despite most branches sharing most of the same texts and practices, the views on the afterlife can vary radically.
Merics for example nearly all follow a branch of Ovarianism in which souls do reincarnate, but in the endtime all souls are judged and will either go to paradise or Midhad (hell/purgatory) based on the deeds throughot their cycle. Many Merics sincerely believe their children are reincarnated forms of recently deceased relatives and friends, making sin especially grave due to the possibility of damning the soul of those who lived before you.
The branch of Ovarianism adopted by most Managians (and many Ocos and Banxer converts) is highly organized, believing that all sapient souls instead of reincarnating on Earth will Go to Paradise or Midhad through a literal rebirth (err, hatching). Paradise is full of Earthly pleasures and delights. While generally Ocos are (currently) more politically aligned and close with the Daws who hold much power, Managians currently hold more power in the realms of faith.
Comparatively few Daws follow this organized form of Ovarianism, usually following branches that reject the idea of a paradise of “earthly pleasure” and believe the end goal of their faith it to break free of such needs and wants like food and sex.
There is some newer highly strict branches dedicated to (in their view) follow a version “uncorrupted” by change. One such (small) branch views souls as being “recycled” in death, but like the Meric branch believe in an end time where the Earth will end souls will be judged. Unlike the Meric branch however they believe that all souls that don’t go to paradise will be destroyed (basically everyone who isn’t them). They also believe Ocos are the only ones eligible to going to paradise and other species are more or less “talking animals”…
