This corner of her domain is much like the rest of it: damp, chill, and dark. No one's in the area and there's nothing being grown, so she indulges herself with a shower of the sort of piercing rain that drives straight through clothing to soak a person to their bones. No lightning, though. She doesn't approve of storms.
A silvery sphere it's surface a perfect mirror appears a scant millimeter above the ground. It vanishes as soon as it appears revealing someone who looks human with his feet slightly above the ground. He lands in a crouch that straightens. On his back is a fair sized backpack but there are no straps apparent to attach it to his body. He seems unbothered by the rain.
He starts talking to himself, in a language she has never heard before. "Transition compete, time beacons reading as expected." Then he pulls something out of his backpack and fiddles with it for a moment. After that his words will come in the most common language spoken by the people near here. "Translation appears ok."
Gods are a feature of this world and are not quite like any of the phenomena you describe. A god is magical being who exists within a defined area of land, referred to as their domain. Within their own domain, a god has absolute control of the land and can dictate weather, soil composition, plant growth, and so forth. If you were not warded, I could even speak to you directly.
It scales with the size of my domain. In a very real way, I am the land. The more of me there is, the more there is to go around. In addition, gods have the capability to bestow blessings upon mortals, which are minor beneficial effects. I offer the blessings of speed, stamina, vision, memory, waterwalking, and resistance to cold and damp. If a mortal is very favored, a god may choose to make them an acolyte, investing them with a portion of their power and granting an additional ability. My acolyte has access to a memory palace, which stores and organizes all the experiences she has lived and allows her to show them to others. Any avatars of mine have the same ability.
The skin on zabna's hand splits along a previously invisible line in the palm. His fingers go limp and a mass of metal rods pack away the now empty skin in his wrist. Where his apparently human hand was there is now a veritable forest of ever thinner metal spikes. "I'm a human mind wearing an ultra-articulate body. If this body was to be destroyed I'd wake up back at the hub missing some memories but otherwise intact."
They pass through forest and fog, ponds with thick reeds poking through and apparently grassy expanses. The ground the heron guides him over is mostly solid. Slightly squishy, but he won't be leaving any boots behind. The entire region seems to be wetlands of one sort or another.
The inside walls are the same grey stone as the outside. Ensconced candles along the walls provide ample light, and there are several arrangements of comfortable-looking chairs and bookshelves. Directly across from the entrance is a raised slab of dark stone that is presumably an altar.
"By pure water I meant the most common molecule in water with no other materials dissolved in solution. Unless your world is greatly different from my own I would not expect to find that occurring naturally. As a warning, biological beings are not well suited to consuming pure water, it will disrupt their ability to function in a way which is related to the issues saltwater fish have surviving fresh water."
"Among other things it's a very good conductor of electricity. It can also be used to filter water but using it for that produces pure water which is mostly useful for use with machines. Being able to produce graphene also means you can probably produce carbon fiber which is lighter and stronger than metals for most purposes."
"Impure water leaves behind residue when boiled so any machine that relies on repeatedly boiling and condensing water will have a longer usable lifetime with pure water. Pure water is also more useful for cleaning sensetive machinery. If you're aware of electricity, pure water is safer than other types of water for extinguishing electrical fires because it's less conductive."
He sighs, "Some types of atoms are not entirely stable, this can result in chain reactions with far more energy output than traditional chemical reactions. Such explosions are dangerous even beyond their raw destructive power because they produce poisonous materials that persist in the environment."
"The Institute has had centuries of time to develop technology it would be difficult to list all the technologies we have. The ones that are most straightforwardly useful at your level of development would probably be indoor plumbing and electricity. At least to your followers. For yourself electricity can lead to computers which can effectually store libraries worth of information in a space smaller than my littlest finger."
"At a certain level of abstraction I am one. But I do also have more readily distributable versions, The primer tablets which is what we call the devices we've designed to distribute recharge if left in the sun. They have all the knowledge relating to our nonviolent technologies which aren't ludicrously dangerous, though with time and study you can get from what we give out to where we are." He produces a rectangular device about a centimeter thick and the size of a large book and places or on the altar.
"Not really no, there's four copies of me that I know of. I was born on a world far from the institute, I got copied by powerful magic with something of a mind of its own, and two copies have been derived from that one, me and another who is travelling back to the world that I was born on."
"It was troubling when I first realized what had happened, but only because of the difficulty involved with seeing those I love again. I would be surprised if you could maintain that connectivity between different planets. Nothing we've encountered so far has been able to send information faster than light, and while light travels extremely fast, it is not infinitely fast."
"There are paths through reality which we call threads. You can through either certain magics or advanced technology throw yourself into a thread. While you're in a thread you're travelling at the speed of light but no time passes from your perspective. You can ask magic or someone else at your destination to pull you out, though it is possible someone you weren't intending to meet can pull you out instead. Our first line of defenses for our worlds rely on pulling people out before they get near our worlds."
"That doesn't surprise me, they're only really useful when you have the technology, or a form of magic that lets you make bobbles [zones of frozen time that dissipate after a certain amount of time has passed in the outside world]. The local language doesn't have a word for that though so I doubt you have a way to create them."
"The Institute is a complicated organization and a very large one. The Explorer corps is full of motivated people, but it's not very competitive given how much of what happens is more or less down to luck. We don't know much about most of the worlds we visit before we visit them. The Institute overall is run by a group of people called the directorate. The directorate is chosen from among the people who achieve a rank equivalent to director or above by a vote of people who have taken one of the oaths of responsibility. There's some additional complications to how it all works but that's the short version. So far everyone in the institute either was a biological human or is descended from someone who was a biological human. Whether we all count as human is a matter for some debate."
"That depends on a lot of things. There is other magic in the universe and many systems of magic shape the cultures that possess them just as much as I would presume that Gods shape your world. The world I come from and the world the Institute started on though, neither of them had any magic for most of their history. People told stories of gods and fought wars over what those gods supposedly wanted from them but there were, at least as far as anyone can tell, no gods for them to be following. Slowly and over the course of thousands of years humanity on both worlds invented new technologies, electricity, steam engines, computers, and so many more. My original world progressed slower though, they lacked some crucial evidence for a cornerstone of the biological sciences called evolution. And without that medical care and our understanding of many things was held back."
"Well it took longer for us to discover certain aspects of how things work, especially how infections mutate in response to the attempted treatments, I'm not sure the direct causality for other slowness in medical development. Some history of science people are doing a pretty massive study comparing the histories of the two worlds."
"That's true you aren't on your own anymore. Given some time my superiors will start organizing a larger expedition and that team will be able to help construct a comprehensive plan for rolling out the technology the residents of your world want and the knowledge of how to use it responsibly."
"Usual time windows aren't too applicable here. Your magic is more comprehensive and harder to analyze than most systems we've seen so far. That's going to make my superiors a lot more cautious. Still I'd be surprised if the survey team wasn't here within a couple weeks, and the working group would follow a couple weeks behind that. The survey team will take a census of your world, and check for any nasty hidden surprises, assuming they don't find anything that would threaten a working group the working group will follow as soon as they get the all clear."
"Oh, I'm sorry for being unclear, we're prioritizing based on distance. It's just that most of the close worlds are without intelligent life that our magic recognizes. We have a tendency not to trust our magic though so we go out to look at those worlds anyway, besides, a lot of them are very pretty, or do have life just not life that is intelligent at the level of you or me."
"So, our magic learns based on examples, you can use certain artifacts to peer back into the history how what magic thinks is a book or a person or a boat. Really far back in time as far back as we can look, magic was taught to look for some specific microscopic incredibly dense beings and also humans as people. When we did the first uploading experiments those were not initially classified as people but eventually that problem got resolved, we're still not sure quite how magic made the jump. That makes us reluctant to rely on it for identifying non-human intelligence."
"We don't know. Magic might have learned to extend the definition of person itself from context or maybe someone else who understands magic better than we do extended the definition of person to include uploads. These sort of uncertainties are why my people try to avoid depending on magic."
"That depends on how long you want to spend teaching it, and how many motes you have available. At its most basic, magic can apply forces to objects, create light, create matter, gather information about the world, learn from patterns, do computation, move things into sublayers, pull things out of sublayers, bobble things, interfere with bobble creation, push things into or pull things out of threads and send messages. There were also a lot of less basic compound operations that were taught to magic a very very long time ago, one of those is to recognize people, another is to create illusions that only one or a small group of people can see. It's nearly impossible to use complex magic without that illusion capability providing debug output so I'm not sure how the system was used before that capability existed."
"Sorry, I don't mean to offend. It's just the considered opinion of the Institute that of the magic we've observed so far it looks like someone built it rather than it arising naturally. I'm not sure whether that would carryover to this world and its Gods but it's my default hypothesis."
"There's a pretty wide variety, they usually involve some sort of creator deities. There was this one somewhat polytheist one where there was one creator god who sung other less powerful gods into existence and taught them to sing in turn. None of the gods were in evidence when we visited but there was a music based magic system. Some of their spells were really beautiful."
"Sure, let me play one of the waterwalking spells. Unfortunately, I don't count as a valid caster so it won't do anything but it sounds nice." He gets something out of his backpack and soon there's a quiet contemplative song playing. Ellayania will be able to understand the words that sing about water flowing smoothly and holding together.
"With most of the magic systems we've found so far it's mostly heritable with some additional fuzziness where people either unexpectedly are or are not magic users. Idelia follows that rule. Magecrafters, Wanderdeep's empowered, probably don't, one of the magecrafters known to the Institute had a child and they don't have the power."
"Find isn't quite the correct term. We're gradually expanding our sphere of influence and we're trying not to send explorers too far in advance of our ability to offer support. It takes a lot of nearby infrastructure to handle the integration of a new world, and we also have military forces built up around exploration hubs in case we encounter anyone unfriendly. We're just starting to explore your local neighborhood. We know of three other likely candidates with some signs of magic and one other non-magical world with humans and about a hundred worlds that we think might be life-bearing in this area."
"Well, usually, the explorer on site has a series of teleports mapped out. We talk with the people we encounter and travel between different areas of the world. Under some circumstances, an explorer will contact local governments and open negotiations but usually that would be left to the survey teams. They have more specialized ambassadors with them."
"Alright, I've been writing up the specs of the plane in a side-channel of my mind. Let me just transfer the data to one of the tablets so that Ellayania can read it, along with the user's manuals for the parts I'm thinking of. And there." He takes a tablet out of his bag. Then he takes what looks a bit like a black tarp a small cylinder [looks like a battery] and something that looks like a thicker part of the same sort of metal skeleton zabna showed was inside his hand. "I'm going to need the last one back if at all possible. It's one of the motors I use for moving at my top speed."
"Mostly small-town sorts of things here. Farmers, hunters, that sort of thing. This region of the world isn't heavily populated. There's one bigger city on the coast, that's where most of the imports come in. In more, uh, congenial places there tend to be more people and cities. Monarchies are fairly popular."
"I could probably say more, but everything I know of biology is probably on the uplift tablet. It seems like your world might not have as much to gain as most do from industrialization. Of course, the near immortality of uploading will probably drive you to it industrialize to some extent regardless."
"I think it depends a bit on which parts Ellayania is willing to do. I think I can build most of it myself with the right materials but there are a few bits of detail work that I can't do very easily. It occurs to me that I haven't asked how hard what I'm asking is. I can likely reuse my existing solar fabric if manufacturing more is difficult for her. Otherwise, as long as she keeps the rain away I just need a couple work tables and an area a little wider than the wing span in one direction and maybe half that in the other."
"That's fascinating. If our magic systems are built on some common basis, which I'm starting to doubt, you have a very different set of abilities and limitations exposed. If they aren't built on a common basis I wonder why my diagnostic tools function. I can't think of a principled reason for two unrelated systems to be interoperable that way."
"That's an interesting idea." He pulls out one of his little displays and fiddles with it. "This device is fully charged so at least some of the ambient magic it's detecting has to be my type; but this isn't exactly an magic intensive device, nothing I carry is. The antimagic is apparently compatible enough to keep Ellayania from speaking to me directly though." He shakes his head. "If all goes well, there'll be a research team here trying to puzzle out the answer soon enough."
"I guess it's a difference in perspective. I'm used to thinking of things from a reductionist point of view, where everything, including people and magic, is made from smaller pieces which can be analyzed individually. Maybe the gods here are an exception to that perspective, but I'm not going to assume that given that they would be the first exception."
