Would still like to know how mankind deviated into so many different variants

The fact there are tales about Azim creating Raens and Nhaama creating Xaela makes me think Azem (us, Venat or another one) created some familiars that became a species, and a Nhaam-something created Raen. Same for Azeyma being the guardian deity of seekers. MAYBE we'll have an hint in the next raid 24 about some ascian named Halona that created pointy ears familiars, who knows ?

If you adhere to the "allagans are just a lawful evil version of ancients", it's the same that happend with ixalions : they created a race (slave-race, in the case of ixalions) that became a species.

Every "human" race exist in all worlds, so they existed before the sundering. It's said allagans captured miqo'tes, so they did not create them, and G'raha only got allagan blood to prevent the Allagan technology to disappear entirely. Probably an enslaved race, again.

Plus, Venat could totally have created lalafells, since everything she creates is either fluffy, small, round, or a combination of those.

This makes me think, in the case of Au'Ra, if you travelled back in time as an Au'Ra and word got around that all those observers you helped as the then-current Azem's familiar that he/she sent to Elpis was very knowledgable, wise, strong (for a familiar), and thus would like to have a similar one, it might make Azem decide to in fact create said race as a concept, hence you kind of give birth to yourself(race) type of situation lol. Wait it could be true of any race now that I think about it.

Considering you're the strongest and most blessed of Hydaelyn's champions because you're the one she met and adored in Elpis, and that you were to Elpis in the first place because you were the strongest and most blessed of Hydaelyn's champions, we're already in a "give birth to yourself" mind loop xD
