Thanks for starting us off, Bish09!
So magic runs through much of society in small ways–the ways that are harder to track down and fine or jail people for not having a license to use. Kitchen magic, hedge-witchery, and rituals to keep cows in milk and pests out of the field.
There’s at least one person who’s got some skill in magic in every village, and a lot of people have one or three little tricks.
However, knowledge is jealously guarded and the law does enforce the rules about who can legally practice. (Of course, they don’t apply that law even-handedly, but that’s another topic.)
As far as industry goes, I’ve set this story in a broad range between around 1900 and 1905, as far as knowledge goes. But just because some scientist, researcher, or noble out there has discovered some working of the universe, or created some artifact that is the equivalent to the same technology in our time, that doesn’t mean that the average person has access to it.
The problem with this world it that because of the societal structure of knowledge being passed from master to apprentice, and access to magical schooling on a wider scale being limited, and artifacts and other magical technologies being difficult or impossible to produce in bulk, they are expensive and we don’t have wide-spread adoption.
Most artifacts and amenities that the common household might get ahold of have been produced in a pseudo sweatshop by Apprentice level thaumaturges who can only legally work under the banner of a Master.
They have trouble growing their power or expertise because of the diminishing returns from repeating the same kind of magic over and over, without stress or innovation.
Osham has started to move toward what we would consider a modern day Industrial Revolution before the rest of the known lands, but they’re still slower to adapt than we, without magic, were and are.
Coal still is largely used for heating, not engines.
Magic is reserved for industry that has a high enough return on investment to make the cost worth it. Which is generally magical production of some sort.
