I am not actually that interested in magic or power, merely distinctiveness. My issue was this:
1) Orcs villains are, by definition, one-dimensional. If they cease to be one-dimensional, it actually becomes morally problematic to exterminate them. This goes for all faceless mooks in all settings. It's lampshaded in a variety of comedies.
2) Orcs, however, are even worse off than normal faceless mooks because they're defined as being violent-on-top-of-violent. The absolute worst, most cliched, least interesting, violent PCs I have ever seen still have more characterization than an orc. And newly-created orcs -- as here, as in Tolkien, as in a couple of other genres -- are defined by that facelessness
. Pull back from aggression, one can question "orcness." Pull back from brutality, one can question "orcness." Add in any feature that distracts from those two qualities, one can question "orcness." You can be bigger or smaller than normal, but after that it's dangerous territory. That's more similarity than some clones in fiction and twins irl. I have been in half a dozen discussions in my life about whether such creatures can even be considered sentient
! That's a severe level of homogeneity; it's more strict than Warhammer 40k orcs, and those guys are fast-grown straight into adulthood from fungus
3) That means that any orc distinction -- not just magic or religion -- can be shot down. Indeed, it really doesn't make any sense to shoot those down (or, alternatively, it doesn't make any sense not
to shoot anything
can pray. Magic's rules vary from genre to genre, obviously, but no matter what the genre, magic's just a tech (save for when it is wholly capricious -- in which case there are no wizards at all).
I get that there are appropriate restrictions on gender and experience due to the nature of conversion, but after that, picking characteristics becomes mother-may-I and can't be anticipated. Whether or not point (2) is violated is arbitrary for each characteristic. That's great for making NPCs, but I find it more than questionable for PCs.
That said, there are plenty comfortable with this process. I wish all the best and hope you enjoy the game!
