(The Zevs have left the main cabin again. It's a really good thing their room is soundproofed.)
"Not the instruction manual - well, yes the instruction manual, if at some point I wrote one, after which I can produce it in any format you care to name, but I can't generate information de novo."
"Aw. It's like this magic was made so we couldn't abuse it too much. That makes me sad..."
"But if you have blueprints or it was invented by someone else, that's completely fine? You couldn't make immortality serum without someone else inventing it first, but if it is invented, by someone else, could you do that even if you don't personally know all of the specifics?"
"Yeah. I have to be able to sort of - locate it. Like, I can produce a book I haven't read by knowing title and author, and I can sometimes do it with title and first few words or publication date and author or whatever, but I can't do 'the book you're thinking of and haven't told me', or 'the best version of immortality serum invented somewhere in the multiverse I've never heard of'."
"Okay. So you could very definitively create the materials my wife needs for resurrection, but our bottleneck is still the number of witches available. Still useful, but - apparently we seriously need to throw more things at research and development. How do you feel about putting research facilities with your level of technology in various planes so we can research methods whose bottleneck are not witches?" He makes a 'hmm' sound. "And I'm going to bet that you don't want daemons, so asking the alethiometer for help will be difficult. How much information about your technology can you pack into an easily-transportable box or something? Ice and I are rich, we can replicate instructions if given them and sufficient time."
"I don't want a daemon. But I will happily set up labs and fancy futuristic computers for you, and data storage does keep getting more efficient, I can get you most of the world's accumulated knowledge and media on stuff small enough to carry."
"Then we do that, and ask the alethiometer very nicely for ways to use that to make a medical solution for immortality so that it's more easily scaleable. And also make research facilities and hire lots of very smart people to outdo the technology you gave us, and other smart people to use the things that you did give us to improve life for people in general and also make us even more absurdly rich."
"How are we going to explain turning up with technological advantages? Magic I can invent in my backyard, but a hundred fifty years of medicine and computing and whatnot...?"
"Uhh... Hm. We could finally drop the masquerade and say I borrowed it from my world?"
"Someone might visit your world," she points out. "It has only recently heard the phrase 'germ theory'."
"How likely are they to visit my world? We don't even have a portal to it, anymore. But - we could hand it to the colony instead? With the caveat that most of them don't have the education background people from Earth do, what with only recently learning about germ theory."
"Absolutely let's outfit the colony. The colony can even know where it came from, more or less. Maybe we can distill it to something streamlined enough to look like magic and I can act all proprietary about it."
"Sure," he agrees, happily. "I wasn't going to suggest not outfitting the colony, that would be insane, I just - sort of want Earth to get nice things, too. I like my home."
"We make a very cute interdimensional genderswapped soul-bird-having couple, don't we," comments Cam to his angel.
"Is that a roundabout way of saying that you two are cute together, too?"
"We belong on some sort of very forward-thinking elementary school poster," says Cam.
"Phix and I belong in a coloring book in our fullforms," defends Max. "Kitty and deer snuggles are adorable, I'll have you know."
"Ah yes. This is where it begins. It starts at adorable kitty and deer snuggles, and then later you will want pictures of me prancing. Well I won't have it, mister!"
