What they can get, if they walk up the whole Row to see all their options, is apparently a single room with a bed that ostensibly could fit the both of them for five seo per fifteen days (it goes up if they want to buy in smaller blocks), or a room with two beds for seven seos, or two beds in a room with other people for two seos every five days.
"We don't know how long it'll take until the first sale; might have to use the third one. What do you think?" It'd depend on what other expenses there are likely to be, but one of them is in a better position to guess than the other.
"It's your budget. We could price smiths first if you'd prefer; I don't know how much those tend to cost."
"Can you guess at how many, say, horseshoes would cost about the same amount as a thinking human being? Wouldn't have to be a good guess, just in approximately the ballpark."
"Human beings vary widely in price, but if we're using my most recent price as the baseline, quite a lot. I'd need writing materials to work it out but you could probably shoe a whole stableful of horses at least the once for that much."
Presumably they'd charge more for strange precisely specified objects than for horseshoes, but if it's that many times more then I'll buy their metal and rent their anvil and do it myself."
But at least we're set for the immediate future."
"I can cook in the boardinghouse kitchen for us both, if you want to buy some groceries."
"Yes. Depending on how often you want to send me on shopping trips for food one or two seo should do it and I'll probably get change back."
Thanks for your help, by the way. Navigating a completely different world like this one could be much harder than it already is."
But the mutual congratulations can wait until the world is up to a decent standard.
"For the immediate future, you collect groceries and I'll get the room rented?" He fishes around for the amount of money she named.
Paper and pencils, though; those'll be important."
A much simpler arrangement than a boarding house might conceivably be, but he gives no sign that he's pleasantly surprised.
He is informed that he may use the kitchen but must not get into fights with other residents or the landlady's sole discretion will be used in sorting out (and if necessary evicting) involved parties, and there are bath facilities (such as they are) in the back, and he is to be quiet after dark and very quiet after it has been dark for a few hours. And he is shown to the room.
Eventually he collects himself. To pass time, he retrieves a small note pad and pencil from a pocket, and starts sketching out plans and designs.
Aya appears a couple of hours later with food, which she has apparently just now cooked.
