One of the hazards of world-building is creating the society your story is set in. For stories set in the present day (or recnt past), a writer can copy the one around them. It has the advantage of already being in existence. But for a mediaval fantasy, this doesn’t work so well. Especially if it closer to a historial work. And I apologise in advance for a heavy topic. I’ll try to tread lightly.
What passes for today’s current “western” secular society is basically no older than the end of the Industrial Revolution. It was during the latter that family and social structures were upended and redefined. Before the Industrial Revolution, working-class people tended to take up the trade of their father or some other close male. They lived their trade, grew up into it and helped the next generation do the same. The Industrial Revolution changed this. Now working fathers would travel to “work” (often in a mine or factory) and their children no longer got to grow up watching their father work. It broke the transition of child into adult.
