"Apparently absorbing heat takes time, hard to use offensively. Is that related to the religion thing? Efrossians wouldn't survive if they had that problem, their technology is really, really, really primitive. We introduced them to the wheel."

"Yeah, using magic's supposed to be sorta sacred. The theology's a bit muddled on this. And, wow, to the wheel. That is heavy. Why do they need it to survive? Cold world?"

"Cold world, the magic is inducing an ice age, which forces them to use more magic. You see how that spirals."

"There's magic other than what the humans use, or is it just because of them?"

"Just because of them as far anyone can tell. The world itself is more prone to getting into an ice ages."

"That sounds pretty terrible. Hmm..." She pauses. "I wonder if I can convert magic to heat, for these people."

"Convert how?" He asks interested.

"I can convert the three different types of mana into one another, maybe I can do that to other types of magic too." 

"Would you be able to do it large scale?"

"How exactly do you mean?"

"Well, I don't think you can trivially save however many Efrossians from freezing death, but it was worth asking to be sure."

"...not trivially but I think it could be done and perhaps more effectively than via direct magic conversion..."

"Sadly, I don't have an Efrossian at hand so we can't even test that."

"My magic system is very versatile. Especially with metas around. We could probably solve these problems with it."

"Would you be willing to?"

"Of course, helping people is what I'm for, as far as I'm concerned."

He beams. "I'm certainly willing to help with that."

"But at any rate time is paused there, probably, if that world is connected to yours, so tell me about more magic."

"Sure... um, I think next should be Synth, from my own native world Elan. Memory crystals are simple, but should be explained after sorcery, for context. Synth magic allows the combination of the traits of living things."

"It's the thing that makes you so... big?"

"Yup. Combine humans with other humans - or members of the same species - and you get augmented versions, which are physically improved; I'm even stronger than I look and should live nearly four times longer than the average non-augmented human. Combining different species is possible but the result is usually sterile."

"Huh. That's an oddly specific magic system."

Shrug. "I wouldn't know how the multiverse compares but we managed to be fairly creative with it, we've had the equivalent of vaccines for thousands years and can treat if not cure several chronic illnesses. Not to mention better livestock and crops - I have trees that give this amazing amalgamated fruit."

"Okay yeah I guess that's pretty awesome. Plus, it did manage to produce—" she gives him a once-over "—you."

"I'm flattered."
