I eventually came up with the idea that humanity was once very close to the space-age, wherein they could colonize the stars and, more importantly, artificially control their natural instinct and desires and make them work for them. It was at this time did El-Kirsha, goddess of nature and creation, had shown her eldritch visage and started her campaign to exterminate humanity for unknown reasons** which I will explain if anyone's curious**. She turned all life on earth that was not directly under the human's control against them: rabid animals attacking humans, hordes of insects destroying crops, bacteria and viruses seeming to mutate specifically to infect humans, constant natural disasters. But even though many died, man was advanced and gave her a pushback far greater than she bargained for. Whatever weapon from nature she could pull to cull them, humans would adapt if not change it for their own purposes. They developed cures for all her diseases, braced against her storms, and their machines tore apart the vermin she set upon them. In spite of this, they knew they were playing a losing game, but they would defiantly claw and tear at their foe until their dying gasp. It was then that El-Kirsha had decided to play a more direct role in their destruction. Whether by some cosmic law that governs elder gods or simple underestimation, she hadn't intervened directly until now, only sending her countless servants, but it was clear she was either growing desperate or weary. There was no plague or physical aspect to her curse, but it was felt all over the world. Or rather, no new life was felt at all. It seemed women could no longer become pregnant.

Pregnancies not in the late stages seemed to have been terminated all at once, and the late stage pregnancies saw many early births, like the newborns had demanded to eject themselves from the womb. It even seemed that in artificial wombs, all women that developed were born sterile. It was horrifying, but poetic in a way. Humanity warred against mother nature, and now they could not have mothers. They had little time to appreciate the irony of their fate, because even their cloning and artificial womb technology could not keep up with the rate they were losing their populace, it seemed their demise was closer than they thought. But then, it would seem El-Kirsha's direct interference had disturbed another being, who came forth against her and had taken sides with the humans. Ammit, goddess of justice and destruction, had come to be humanity's terrifying savior. Of course, what happens from here is very ambiguous and is only described somewhat in religious texts.

Basically, Ammit and El-Kirsha got in a divine hair-pulling contest which pulled them out of much direct influence of the world, but not before they both left behind various lesser gods as children. El-Kirsha's are consistent due to being based of natural concepts, but different human cultures have completely different pantheons due to Ammitian gods being based off human ideas and concepts, which are ever-fluctuating, evolving, and differ across cultures and belief systems. The Ammitians gods also produced the Nukhepri (monsterwomen) as to give the humans actually fertile women, giving them traits not only from human mythology but nature itself, the latter commonly assumed to be due to wanting to piss off El-Kirsha. Both also left a corporeal bit of themselves behind, for El-Kirsha it was this eerie network of tendrils that form a basal ganglia (reptilian brain) and for Ammit it was a dark-colored, still-beating heart that oozes out mysterious "blood" which looks like a smoking pool of night sky that, after being heavily diluted, is used in the armor of her soldiers. And a third massive basilisk god who was under El-Kirsha's control also rebelled against her but got his ass kicked, and so as a final "fuck you" before he died, he wrapped himself around the dimensions of both the different planes of existence (the cosmology behind this isn't very complex at all, but for the sake of brevity we'll skip it, I'll tell you about it in-thread if you ask), giving humanity access to magic. All these magical anomalies in reality at some point also caused the continents to shift into a very different shape than before.
