Primals not being able to breed is kinda retarded considering the equally immortal and immutable Astrals can squirt out babies just fine.
The whole retconning crossbreeding however is its own kind of writing tomfuckery.
Remember Australopithecus? How about Homo floresiensis, the rl hobbits? Exactly. You don't. You know why? Because our great great great grandparents murdered their ass and probably had those for dinner.
It's just what happens when you serve a society of sapient creatures with another equally sapient ones: they try to fuck it, and the ones they can't fuck, one society murders until the "other" go extinct.
If draphs can't fall pregnant with a human they go steady with, they would not live together, they wouldn't have society, they wouldn't have politics between them. They'd just get bred like cattle and slaughtered so humans could eat some draven t-bone steak.
