"There are hard limits on range but they're astronomical in scale - I could make a star without diving into it or having to move around to get at various angles. But to make something in a specific place relative to other stuff, I need to be operating off plans that refer in detail to the other stuff, or directly sensing the other stuff myself. So I can't just appear a letter on the kitchen table of every house in the country."

"I can rain leaflets over a large area if I get airborne first to have a look at the large area. I will even make them biodegradable."

"This seems a bit like overkill for what's essentially a short-term job posting. I'm all for it."

"Well, we could also include other information on the leaflets."

"Duplicating the next edition of the paper would be ideal, since of course the lead story will be our little stunt today, but most of the places that we can't deliver papers to the normal way will have never seen one before. Not sure what effects that might have."

"Will the places that haven't seen one before contain literate people at all?"

"Certainly priests, often someone who isn't. The priests wouldn't take kindly to this issue."

"Yeah. I could also drop little audio thingies if we recorded an audio message, but those do not biodegrade."

"Mundanity is your department."

"The backup plan is to use the existing telephones and railroads to get as much of a head start as possible, then send messengers from there. It'll work, but there's little real chance of completing the project before the news that there's going to be a nationwide election spreads the sixth-century way."

"I'm pretty impressed that you were able to nonmagically reinvent phones and trains, have I mentioned? When you weren't even planning to time-travel, at that."

"Well, thank you. I was a factory foreman back in Connecticut; had to know how things are put together. I have to say, though, the create-anything-imaginable approach has quite a bit of appeal."

"Oh, yeah, I don't envy you one bit. I'm just impressed."

"I tend to assume that society progressed enough that most anyone from my century would be the best and brightest here. The things I know how to do are probably the most dramatic, but a teacher or a lawyer would be no less the best this Britain had ever seen. Either of them could work the same scale changes, if slower."

"Unless they weren't a people person and got burnt at the stake."

"I don't think most people want to change the world that much. Given motivation levels like yours or mine, probably, you could do a lot with nothing more than germ theory and high school math. Although, I think a fair number of them would probably have gotten smallpox or something, and died before they could do anything. In 1895 have you got rid of smallpox yet? I know that happens before daeva are public knowledge but not exactly when."

"Vaccines had been around for almost a century when I left, but the disease wasn't eradicated yet. That was easier here, with smaller and more command-able populations. I was immune when I came here, but I suppose if you don't have it at all then nobody would bother with the immunity."

"Right. I mean, I won't get it, but that is because I am a demon, not because I am from the future."

"Would you be able to immunize someone by looking at them? Create the antibodies by looking at them or some such? Cowpox infections are far better than the alternative, but not exactly pleasant."

"I can make antibodies, yeah. Or just a rack of state-of-the-art vaccines."

"That sounds like an excellent idea. The state of the art has changed little in the last hundred years, but I imagine it might in the next three."

"Quite a bit. Although smallpox in particular didn't get a lot of development after it was eradicated."
