"How did these items get made if there's no way to learn magic? Are the magicians homeschooling their children and not writing any books? How did you learn?"
"Half this stuff is antiques," says the shopkeep. "Look, asking me a dozen times isn't gonna make the answer more to your liking. I don't have Hogwarts in the basement, deal with it."
"But where do you get the stuff that isn't antique - who made the Avalon itself? - isn't anybody panicking about the medallion supply? -"
"Kid, nobody knows how to make medallions."
"But some people apparently know how to make luck charms and protection amulets!"
"I'm not going to give out my suppliers' personal information. I wouldn't do it even if you weren't annoying."
"There have to be books -"
"Does this look like a library to you?"
"Yeah. Human intervention - er, personal intervention - to draw, personal intervention to speak. But not necessarily very much; we can trace, we can refill the wax with water over and over. Neither maximally convenient nor maximally inconvenient."
"To be honest, I think magic is a point in favor of there being a deity of some kind, benevolent or not. Physics as a system is self-contained enough for it to make sense as a spontaneous generation; magic seems more arbitrary. But then, people thought that about the natural world before they learned better; I certainly don't consider it proof."
"Yeah, between magic and the angels and demons I'm not sure I can call myself absolutely an atheist. But I do maintain that if there are one or more deities they are inadequate in scope of power, in managing same, or both."
"Fair enough. I wonder if you could print a spell, if you did it differently than xeroxing it. Making a stamp, for example, I bet that would work given that the wax tablet does. You'd want to be very, very careful inking it, though."
"I don't know off the top of my head. I wonder if we could find a mundane phone book anywhere around here..."
"Are those made of carbon paper...? I'm not sure I could reliably double-check runes against a lot of text, anyway."
"...No, I mean to look up the kinds of places that would be likely to carry it. Stationary stores or office supply stores--I don't know where you can buy carbon paper but I have some guesses that it would make sense to look up."
"Given how many unconventional ideas we've had it wasn't unreasonable to assume this was one of them."
He writes this down. "What else...we're thinking of so many things that are obvious in retrospect, I'm half tempted to go through my room and inspect every single object for potential runic applications. Can you project runes onto a surface with a prism, I wonder, and cast from the projection as long as a human being is holding the prism?"
"Oh my god, that would be amazing, if you could just flick a switch and it would count as new diagram!"
"The system doesn't seem set up to be specifically obstructive, printing issues aside, I bet there are dozens of exploits like that and the water in the carvings and carbon paper."
"This is the low-hanging fruit, of course. The real challenge is developing good spells to use these exploits on."
Delighted hugging. "We're going to revolutionize--I suppose there's not enough of a field to revolutionize. We're going to fix that. We're going to fix magic."
"We're astronaut wizards. There were totally people living in the prairies before the white pioneers got there."
"The word 'pioneer' still has a meaning even if its primary historical associations are inaccurate."
"True. On the other hand, astronauts are cooler. And wizards wear stars and moons on their robes anyway."
