The Atum/Animus is not a sign of wisdom, let alone Royalty. This text makes it clear: The crown is worn by "those warriors or sages that have cultivated enough strength", and the shiniest and most glorious examples were those of the demiurges that ravaged the multiverse in their greed. Whether a character has a few soul flames flickering around their head or a full demiurge-halo-crown, this does not mean that in this moment they are speaking or acting with wisdom, it means they are speaking or acting with willpower, which of course translates to magical and martial power in this setting.
This gets pretty obvious in the exchange of Maya and Meti:
Maya, who is an idiot-warlord thinking herself a god at this point in her life, has her radiant Atum crown; Meti, who as far as we know is Royalty, does not even have a flicker of it.
So this?
And this?
Those are not scenes of Allison attaining or demonstrating any semblance of Royalty. That's Allison deciding she'll make herself a King - a thing Royalty would never do.
Her subsequent actions - disregarding the Republic's guardsmen as beneath her and stepping on them as if they were dirt, for instance - are indicators of her becoming more like the demiurges, which indicates to me that Zoss has failed to find an heir he would consider worthy once again. If all he needed was someone like this Allison, well, Mottom and Solomon would have fit the bill. And hey look:
In a moment in which she divides YISUN's many selves into "people who matter" (herself, her friends, her enemies) and "people that don't deserve to even be addressed or acknowledged" (everyone without the power to match her), there it is again! But bear in mind, ontologically, cosmically, these people are no less God than she is.
