Affirmative sign about that plan. "...not sure I can do the matter-from-nothing?" she remarks. "Did you see me do that?" (She's not entirely sure she's clear on the concept behind the 'matter' word.)

"Can't be taught, not that we know. Or they know," she nods at Genea, "we're not from the same place, in the being born there way, I'd just moved over. The different-people-live-different-places-and-differently kind of not same place, not the kind where we're here now.

And all our" (she indicates herself and Genea) "ancestors came from somewhere else, and I'm pretty sure they didn't have mages there either. 

As far as we" (just herself, this time) "know, you get magic from mage sparks. They attach to things - animals, people. For humans it's before they're born, not actually sure about the animals. You're human, you have a magespark, you're a mage."

"You can create heat. That requires some sort of process, a release of energy stored somewhere else. Coal has chemical energy, the sun and stars will burn out, after a long, long time. We have observed the death throes of stars. If you get heat without taking it from somewhere else, that would break the rules we know about the world. Not to mention teleportation. How can one go from place to place without occupying the places in between? I want to test if you can teleport faster than the speed of light. Later. Low priority."

She does take off the coat.

"Fire makes heat? If you rub your hands together, you can make heat - not very much of it," she looks at Aye and the heater, "but heat." Once she's said that, she notices after that she's not in actuality tried either of those here. "...Does that not happen here?"

'Create' seems a bit of a weird word for heat but she's not quibbling over words when she's translating anyway. (The concepts for 'sun and stars', meanwhile, seem to have all sorts of pieces she's not seen before. Also that sounds rather worrisome.)

"Don't think I'm teleporting the heat. Not sure where I would get it, if I wanted to do that? Pretty sure I'm teleporting me though.

The speed of light?"

"Fire releases energy in the form of heat. Wood contains more chemical potential energy than ash and carbon dioxide, the products of a fire, does. Energy has moved from the wood to the air. If you run your hands together, you must exert your muscles, which are ultimately powered by the energy in the food you eat. All energy comes from somewhere as we understand it. And yes, light has a speed. It takes a brief time for light to propagate. Unfathomably fast, three hundred thousand miles per second. But not infinite. All this was found out through methodical experiments and reasoning, in other words, science. My question is, where are you getting the heat? It cannot be from your body, or you would already be collapsed in hunger."

Fortunately, since Aye is keeping track of this to translate, she can ask Aye (silently), and not the Captain, to repeat it. And since Aye is translating through concept, what she receives makes more sense to her than 'chemical potential energy' would. (Somewhat). (Also the concept, at least as best as Aye can currently translate it, is not so far from 'fire eats wood and makes heat', which she's already aware of).

Her understanding that is probably not the important part of the conversation, anyway.

She's not really sure how you do experiments on most of that without magic, but it sounds all sorts of fascinating.

"Well, I do need to eat," she notes, since it's not like she's planning on hiding that. And can starve, she decides to not add, for the moment.

"Pretty sure I'm not getting heat out of my body though. Or my food. Guess you could say I'm getting it from magic, when I do it like this?" she raises a hand a heats it up for a moment. "And I do what I did back on the beach I'm putting something down, with magic, that'll be doing that.

Don't think teleportation is quite instant? Don't think I turn into light either though, pretty sure I'd notice that.

...So if all energy comes from somewhere, is there a way it all got there to begin with?"

"But does how much you need to eat change if you don't do any magic? ...Where does it all come from? That is one of the great cosmic mysteries. We have no idea. We could be totally wrong about conservation of energy, too! Especially since you showed up and seem impossible!"

She thinks about it. "I think so? But not really that much, more like the 'eat more if you're running around a lot'.

Well, we're likely enough not from here. Unless it's on the other side of the world or something?"

"That's... Possible. I have a map of the known world somewhere in my packs."

He starts looking around for it.

While she waits, she tries scrying for local mage sparks or mages.

There are absolutely none of those anywhere in her range.

"Here we are, one map of the known world. We are currently... Here." He points somewhere north. Very, very north.

"Known world? Is there an unknown one?"

"Not as far as we know, just the one spherical planet. There are other worlds but we cannot go there. So, it's a phrase. Africa and Siberia are not fully surveyed, nor is much of the vast Pacific Ocean. The parts we don't know yet are Terra Incognita."

"Worlds you can't go to? And that doesn't look very spherical." She illusions up a map of her version of a known world. It's a much smaller map, the river fork in the center and the thirds marked off. "Well, here's where we're from. Over here for me," she indicates what Genea would call Tscher. "And over here for Genea and also where we were before we ended up here."

"...I'm not sure I'm up for explaining the solar system right now. Bit tired. And I was never very good at astronomy. The Earth is a sphere. There are other spheres, we can't get to them. If you keep going straight, all the way around, you come back to where you started eventually. And you can't simply take a flat piece of paper and fit it on a sphere, it'd overlap in places, so this map is intended to look sort of like what you'd get if you tried that, preserving the approximate shape of the land but making the bits at the top and bottom too big in comparison to the rest."

She gets some of it from the concept behind 'solar system'. 

"Sorry about that. That's interesting though.

We're probably a sphere? We're curvy, anyway. Don't know what the rest of ours looks like, though."

"I think there's some measurements you can do with the sun."

"Yes, solar measurements! I read about those - very clever... Anyway. I want to circle back to what you can do, maybe try to put some numbers to it, for planning purposes. Heat. Teleportation. Healing?"

"I do healing."

"How many times could you teleport like you did for us in a day, with appropriate breaks to rest? Would smaller payloads help? What sort of area could you heat, say it lasts a week, instead? And how many cases of frostbite or flu could you heal? It's alright to guess, I want a rough sense of the tradeoffs only."

"Doesn't work quite that way, with the tradeoffs? Some, not all the way. Like - running and picking things up with your arms. 

Teleportation's got a different limit, I know that one." She says it again. "I think it gets smaller if I start bringing more stuff? Like I said. Not completely sure though. Also I think if I bring more stuff it starts trading off more the other way too. But I haven't gone around trying a lot.

Oh, also there's time, if I do something I can't do something else at the same time. Or, not with a lot of things."

"But you could perhaps make several trips like that in a day, or spend your time warming areas, or healing, or some other thing, is the idea? You won't run out of magic?"

"I won't run out of magic. Won't run out of arms or legs, either. I'll get tired, if I do enough. Too tired to do more, at some point. Pretty sure I will, anyway, it does happen to mages."

"I see. So, I'd like to work out what is a reasonable magical workload for you, prioritize based off of that. Once all our people are safe, we could work together to find other survivors, and help them as well. Or allocate some time to experimenting. Our technologies augmented by magic seems likely to be very useful. All assuming you are willing to help, of course."
