Sarenrae chooses to believe in hope. In the possibility of Good triumphing. In helping others, to be helped in turn. And Nirvana follows where She leads, because they know Her to be far wiser than She thinks.
Iomedae is swayed, by the balance of probabilities and by the desires of Her allies and of others in Creation; and the expressed wishes of Cherry are prominent among them, for Cherry above all others helped bring this about, and so her wishes count for more, in the outcome that is to be Good by Cherry's own values.
Not all of Lawful Good is so swayed. Erastil would rather tend peaceful gardens than risk all to save those outside Creation. Torag holds the duty to protect one's own above the need to help strangers. But Gruhastha is minded to accept the quest, to seek power through knowledge turned to Good ends.
Abadar does not wish to trust in hope. He does not wish to turn down an offer made in good faith. He wishes to close Creation, until such time as everyone in it can be consulted, and then to carry out their choice in aggregate. But He can see that there is not enough consensus for the first step, and He will not wage war on Chaos to enforce what is right, for war is not His way.
Irori does not truly care whether Creation is closed off or not. He will continue to perfect Himself. If it is closed to Him, He will grow better until He can leave it anyway. If it lies open, He will grow better until He can withstand the dangers that lie outside it. But Nethys offers something better. For all the gods to grow, together, in a common quest for truth. He adds His vote.
Pharasma does not wish to take any unnecessary risks. She does not care about those outside Creation, no matter how friendly or Lawful or Good they may be. The new aliens don't even have souls, and so they are as nothing to Her. Otolmens, too, wishes to make Creation MAXIMALLY SAFE, and cannot be offered anything else that She values as much in trade.
Valmallos wants for magic to remain rare, and expensive, and difficult. It seems unlikely that He shall get what He desires, with fixity fields common in Creation. But still He bargains with what influence He has, to make the Future even a little better by His values.
Urgathoa values existence, and feeding, and breeding, and life without death. She can tolerate life without suffering inflicted on those who do not wish it, if it is the only path left to Her. The gods of Good triumphant seem less likely to leave Her in peace, if Creation is closed off, and bounded, and watched closely. She asks for an empty realm Outside, for Her to fill with Her offspring who may leave it in turn when They so wish, as long as They do not intrude unwelcome upon any others.
The votes of Chaos were never in doubt. But They remind everyone else of the price that must be paid if the decision is made against Their wishes, and of the new war that must then be waged against those of them Who will not submit.
One by one the lesser and the greater gods, all beings in Creation whose minds understand the question and who can respond within the limit of time set by Asmodeus, cast their votes. And for all those who cannot attend, simulations and estimates are added, by Abadar's knowledge of all beings He has traded with, by Iomedae's desire to do right by Her allies and by those who would be Her allies if only they were given the opportunity.
