There is a small man with a paintbrush in his hand, kneeling on dry cracked ground beside a large round metal plate, painting the plate with coloured inks drawn somehow from glass spheres in the open case that lies on the ground beside him. Occasionally he checks his work against the book propped up beside the case.
"If you can make tiny models of houses is there any way you can make, like... tiny figurines, not-alive ones, of people?"
"I can make them small people, but replacing the materials requires knowing more than I do about what materials are involved. If they're human, I could do locks of hair, say, if they're tentacle aliens or at the moment I try to conjure them from they are being made of crystal shards or something not so much."
"Huh. Okay. Then please do make your basement-dwellers somewhere I won't have to see them."
Tiro takes a delighted little tour of his delightful house. It's so nice. He is so happy.
There are no other people on this planet. Well, maybe they're microscopic or something. But if he finds a way to check that too, nope, there are no other people on this planet.
Cam doesn't actually check for microscopic people. He comes back to Tiro's house and reports that they're it.
"Yeah. I mean, it was possible that there were more people, but... I didn't really think so."
"It would have been interesting to find out how they got here if there were any."
"There might have been an actual enclave of whoever used to live here, somewhere. Somebody could've dug themselves into a hill and actually survived there. But I wouldn't expect it."
"I'd expect an island. There's a little water left a couple places, somebody on an island could have had a moat's worth of ocean left."
"And whatever drove everybody underground could've been unable to cross it and kill them all?"
"Okay, so I'm going to teach my computer your languages, so you can read the machine-translated books too, and then do you want to divvy up all the books with 'alchemy' in them or look at them together?"
"I think it would make more sense to look at them together at least until you're caught up on everything I already know."
"Makes sense. Do you have a very ballpark estimate for how many words have ever been written in each language you speak?"
"I shall take that as a no and assume there is not terribly much writing about on your planet!" says Cam. "Printing press is a pre-computer mechanism for distributing writing without having to have scribes copy it over all the time, literacy is not a huge priority for most societies before that."
"Oh. No. There's a few book-copying artifacts, the royal library has one, but nothing on the kind of scale that sounds like."
"So I can probably fit the complete written output of your civilization in a nice dense format in my storeroom." Nod nod.
