"Just having a look around. I would say I come bearing gifts but the gifts don't actually exist until I make them, and I don't know what you guys might want or your weight allowance."
Shortly Cam has a crowd of people shouting things. Rata turns around and yells them into a line.
Most people want tools and raw materials of various sorts. One person asks for a replica of their wedding ring, which fell off years ago. Another one wants a mirror. They don't seem to get that Cam can do complex machines yet.
After a few minutes, the guards come back with friends. The person they're escorting just ignores the line. Nobody calls him out on it.
"Kind stranger! Lord Helric would like to welcome you to his realm, humble thought it may be. Unfortunately he cannot come see you personally as his health is not what it once was. I am his representative."
"That's entirely possible! This isn't very organized at all. What's your plan?"
"I would have you discuss the broad strokes of whatever advanced technology you are capable of with the head librarian and the other ministers while our clerks tour the districts and assemble lists of personal desires, with relative priority marked. I would then speak to Lord Helric to hear his judgment on the balance of weight and altitude while you fill some of the lighter requests. We would want infrastructure conveniences filled first and personal ones second."
"It's tidy that you can expect to go around and get a wishlist from everybody in town by sunset, I mean."
The library manages to be quite stereotypically stuffy, with a classic old-book-smell mixed with more local flavors of paper, but there is enough clear space for a dozen people near the front. Helric's representative introduces him to the Guardsmaster, Weightminder, Chief Grower, Head of Construction, some less important ministers, and the Head Librarian herself. Most of these people are fairly elderly.
"Technology. It's not exactly lost technology - long story - but it's basically the same idea, and if you have a really specific idea of a lost technology you want I can replicate it. I can make helium, which doesn't catch fire and is almost as light as hydrogen. I can make food you don't have, and seeds for it. I can do medicine."
