It's not entirely clear how much they're doing business collectively and how much they're doing it as individuals.
Their steel is cheap enough to make thanks to automaton labor they can undercut sun mages a bit. It's not as good as titanium or other metals for some things, but it's very cheap. If they end up using most of it internally and not selling any, that's fine, the steel mill will just make less steel, that's how markets work. There is a small inn in New Dover, above a pub in the best English fashion. Someone's raising an apartment building next to a spot reserved to be an airport eventually but it's not ready quite yet.
Nobody seems interested in renting physical shop space, but some kind of distribution deal where a shop-owner regularly orders from the industries here might be workable. That knowledge mage partnership sounds like a grand idea! They have all sorts of other ideas for knowledge-mage-integrated instruments too! Bulk discounts will have to be worked out with a half a dozen different people. Yes for toys, clothes, alarm clocks, and little essi-vehicles. No for big vehicles, watches, furniture, automatons, and music machines.
The pub would like an amount of food delivered every month. The farmers are kind of skeptical about magic help but will try it out and see if it's worth it. They have an auction to sell the "chickens" Valanda donated (a farmer wins and starts selling eggs) and give the proceeds to the Order of Mercy.
Selling a human child: NO.
...How much is the baby belul? They have birth control, thank you, do you mind not discussing that in public?
They start building a schoolhouse. Basic education is free to anyone below their age of majority who shows up, whether they're free or slaves or human or not.
The structure mage who wants to apprentice is a child. Who owns them?
