Its cuoatls and erinyes for the record. Chances of successful breeding should onviously be low but i think it probably would work with a powerful, corrupt, and obsessed enough experimenting mage binding enough of them.
I mean't the other kind, the ones that are angel/devil hybrids.Nephilim would imply it involved mortals at all.
I realized there was a better way to put my response to this. Its less like angels bred with devils and more like small piece of the dark side of a massively powerful god reconstitutes with small piece of its light side. The normal angels and devils are normal angels and devils. Not pieces of the god itself in raw form.I mean't the other kind, the ones that are angel/devil hybrids.
