She considers her options, briefly, then decides that she really can't resist investigating. Risky? Perhaps. But it'll bug her if she doesn't figure out what's going on. She informs several people that should likely know that she is going into a strange magic bar thing, and then in she goes.
"I might as well explain," he sighs. "I came up on the continent of Irahali in the shadow of an enormous plague god who was starting to feel the scarcity of living followers. That's why I chose the power I did. With my acolytes' help, the remaining mortals in and near his terrain ceased to fear him, and he went out fast after that. I moved into a corner of his former territory and did the best I could with it. But I soon noticed that most mortal rulers were... less helpful than they could have been. I asked my followers if they would prefer a god-king to the mortal variety, and they said yes."
"Being a god-king turned out to suit me very well, and I was a little too successful. Some of the younger gods nearby tried to clean me out, failed, and died. My neighbours of both the divine and the mortal variety found themselves losing followers and subjects to me at what they considered an alarming rate. If a country tried to conquer me or a god tried to wipe me out, and they failed badly enough, their people would need looking after; I kept expanding. And eventually I ran out of places to expand to. I maintain a strict policy of claiming no land on any continent but my own, these days. I don't want to start the cycle up again somewhere else."
"I hope the same," he says. "I advise that if you're ever tempted to become a god-queen, you think very carefully about how your neighbours will react. I don't exactly regret my empire - I think I can do much more good for many more people this way - but I wish I'd been able to come to it more peacefully. And I very much wish I'd been able to peacefully coexist with - any other gods at all."
"I have embassies. My acolytes collect and distribute disease immunities in as many places as possible. I have holy artifacts in dozens of foreign ports. But I am generally very careful not to intrude on anyone's domain, unless I need to sail a ship through it, and then I have my diplomats make offerings as they pass."
Up she gets! But of course, that's no barrier for a conversation now.
"I should probably mention," she says, via her rock, "I am a volcano goddess who has been very careful with her public relations."
"On my continent we have a, ehm, stereotype about volcano gods. Largely because of an obnoxious little twit far to my southeast called Kalandax. Mostly that we are crazy and murderous and like blowing things up. But either way, usually when I tell people I am a volcano goddess, they tend to back away slowly. So, careful public relations wording."
They turn out to make a really excellent team. They want the same sorts of things. They have powers that work in similar, companionable ways. Somewhat hilariously, they even have blessing sets that work extremely well together. ("Danger sense and a resistance to panicking, both - I don't think we could have planned that better unless we sat down after starting and working it out," comments Tisvetaia.)
More holy objects are exchanged to bless each other's mortals. They bless each other. They bless and poke people they meet in Milliways, often taking different sides of the bar to cover more ground and informing each other when they find someone who could use some blessings or pokes of a specific kind. And sometimes the bar is empty, and they can keep each other company and talk about how their domains are doing.
During one of these moments: "It strikes me that you could send a couple animal manifestations to my domain, to spread and collect disease immunities. I already have a system set up for people petting animals for immortality, my mortals will adjust pretty well to it, and obviously we can just coordinate as we like. I don't think my neighbors will mind."
In they get to go to her domain!
Her domain is nice. It's warm and fertile (which is unsurprising, since she's a volcano goddess) and her temples accept people in need and provide them with food and lodging and if they would like, something to do. She gets along with the established mortal government (and has a habit of prodding the nasty members of it to get them to stop mistreating their people, and blesses those who are good...) and makes a habit of making it clear that if people would like to talk to her they can address her directly. She organizes regular immortality poking rounds, of which she neatly incorporates Kirovalin's birds into.
His population is very pleased about this cooperative effort of his.
That is to say: Three hundred million people discover Tisvetaia's existence and are pleased about it.
There are some things she loves more than the rush of power from lots of people thinking about her, but it's not a long list.
There's only one thing to do in response to that, isn't there? Make more birds, obviously, and cover more of Kiro's domain, and distribute lifespan extensions more thoroughly. Whee!
(Also expanding her domain a bit and maybe adding more to her efforts to make that decay god neighbor of hers go away, and add another human manifested form or two to run around and poke more people outside of her domain...)
"We are likely to need some expansions to deal with extra population," she muses. "Ultimately part of your empire but technically under my control and general authority, prod you for major problems or things I don't know how to handle? It's not like I have practice ruling mortals. I'm not unwilling, mind, just - logistics and organization structure are important."
"I'd appoint a human governor to start with who would answer to me on matters concerning the empire as a whole, but you would be the local source of divine intervention and the local authorities would answer to you on local matters. I can take your manifestations on a tour and show you some of the uses of power that my citizens expect of me, so you know what you're getting into. You could decide later whether you preferred to take over the governorship or leave that in mortal hands."
He describes upcoming public works projects to her: routine adjustments like managing the water table and boosting crop growth in underperforming areas, rarer interventions like altering the course of rivers, things rarer still like creating veins of ore to be mined - if 'mined' is the word when all the mortals have to do is come chip it out of the walls of caves. His people know that they can petition him for these things and be pretty sure of getting them if they put persuasive enough arguments or numerous enough supporters behind it.
Kirovalin expands his domain under the ocean in the chosen spot and raises a large island, comparable in size to the neighbouring province of Navehneni, which is also an island of its own. The size isn't arbitrary; he makes sure there is room for every citizen who wants to settle there immediately, plus more space to expand into later.
And then he unclaims the island and lets Tisvetaia move in, along with shiploads and shiploads of mortal settlers.
She's organized, efficient, and she pays attention. She notes that Kiro's citizens aren't used to warmer temperatures, and keeps the province purposefully colder than her original domain. It's still noticeably warmer than the rest of the empire, but not so much that the citizens are uncomfortable with the shift. She has an easier time with farms and fertility, as well - she doesn't have to fight with temperatures and her soil naturally is very rich. She manages the water table and watches the crops and tends to send gentle rains during the night to water them when necessary. She adds little interesting fruit trees to the islands and small fuzzy creatures that everyone agrees are adorable and make excellent pets. She sets up hot springs with little stairs already carved up the mountain (technically a volcano, but she'll never erupt). She has her manifested birds subtly preserve buildings (to resist rot and the like) and works out where roads are going to go with the governor and then makes them herself.
She obviously enjoys herself a lot, and works very hard to keep citizens happy.
Time passes, and passes, and passes some more.
When Tisvetaia has been overseeing her province for a little over a year, a new set of coins are struck at the Imperial Mint. Instead of Kirovalin's face on one side and his bird form on the other, they have Kirovalin and Tisvetaia on both sides, human and bird. The old coins are still valid, but all new ones will follow the new style.
It is a few months later that she reasons out that not only is it safe for her to offer him acolytehood, but also a good idea. And more importantly, she's actually willing to.
(Look, he put her face on his coin, he purposefully gave her an island, she's pretty willing to just. Trust him.)
"So," muses her Milliways manifestation, as if this was a random thought instead of several months of careful deliberation. "It occurs to me that there is an obvious way to become more efficient at this 'poking all mortals' business." She circles the rim of her cup of tea with a finger, only a little nervous. He can likely tell, by now. "How do you feel about being made an acolyte?"
Yep, she sort of figured he would be. She can wait, even if it's a little maddening. She doesn't need to fidget in this body. One of her birds hops nervously on top of a rooftop. Hop, hop. Fidget fidget. Good, that's out of the way. Her Milliways manifestation stays still and waits for his answer to that particular question.
All of his manifestations take to wearing her holy objects, in her customary dark stone and the large-round-pendant form that is the Imperial standard for acolytes. Distributing the benefits of their respective powers becomes vastly more efficient.
About a month later, Kirovalin's manifestation in the bar finds Tisvetaia's, and hands her a wooden acolyte pendant.
Snuggle.
She does not make him regret his choice, either. She wears his holy objects in all of her manifestations, in the same imperial standard of pendant. Wood, instead of her dark glassy stone. They are extremely efficient with their magical pokes. Her neighbors near her original domain think she's insane. She doesn't care. Their citizens are happy, and they and many others in the multiverse are poked.
And in the quiet moments in Milliways, they cuddle.
