To a first approximation, babies on Golarion do not die anymore.
The young people don't understand this; only a handful of humans really understand that half of the children used to die. If you tell them that the babies don't die, they are confused. There are hospitals for children with rare birth defects. Occasionally they die in accidents. Some are still eaten by monsters. Some of them die in their sleep, for no apparent reason. But Naima's mother lost two children, and her mother lost five, and this was the young people today can scarcely comprehend such grief.
In every city, artificial witch patrons cure diseases. In every small town, pharmacists, the intellectual descendants of the medical alchemists she trained herself, dispense medicines of all kinds. Her husband's teleportation circles connect people across the world. Nidal stands untouched, of course. But Osirion is wealthy and well educated, and Cheliax is not the cesspool it once was. The babies no longer die on Akiton, no longer die on Castrovel, no longer die on Triaxus - still die on some of the moons of Bretheda, admittedly, but not in the numbers they once did.
Naima's own children are grown and mostly dead, but only because they want to be. Her grandchildren are grown, and many of them dead, too. Her own body has been shed and exchanged for others multiple times. She has written books, and built community centers, and watched generations of apprentices grow up and have their own children, and - she has won, here. There are other battles to fight, but not hers. Despite that, though, the Boneyard remains very, very full, and it has more children in it all the time. On a million other planets, the battle rages on - or, worse, it is not even recognized as a thing that can be fought in the first place.
They make the decision together, of course. They don't go for the Starstone. Hundreds of people have become unscryable following their attempts, as if they've simply ceased to exist, while four of them have reached true divinity. These are bad odds, and they don't know what the Starstone is filtering for. On the other hand, one rat has eaten the moon god, and that rat is a god, which really suggests very little filtering in the process of gaining divinity by eating gods.
They don't have a moon god to eat. They eat what remains of Aroden.
The first thing she realizes as a goddess is that eating Aroden's remains is not actually safer than the Starstone. The Starstone doesn't obliterate people. People are obliterated by a collection of existing gods annihilating almost everyone who ascends. If prophecy worked, Elie would probably have been killed immediately. But Naima has a moment, and she uses that moment to wrap the pieces of her godstuff around his, making it utterly impossible for anyone to destroy Elie without destroying Naima. They are here as a set; the great beyond will not have one without the other.
They don't destroy Naima. Pharasma does not often put Her weight behind an infant god, but for Naima, prospective goddess of medicine and motherhood, whose primary focus is to keep children out of the Boneyard and in the arms of their mothers, She stretches out Her hand.
