I mean, this is writing we’re talking about, so the causality is inverted: they lack tin because someone wanted them to use iron.Kitsunes use iron because they don't have tin/bronze deposits, so yes they retained iron forging according to Alypia:
I also find this rationalization funny, because you can make bronze without tin. There are a variety of other metals, such as arsenic or aluminum, which can be alloyed with copper to make bronze, which can be even tougher than traditional tin bronze, and, looking at the melting points of these elements, would likely be a lot easier to produce than iron.
I immediately thought of Gor, in which that’s essentially what’s going on.I'm gonna make a guess and say it's The Seven actively sabotaging tech progress to keep people dependent on worship.
Wasn’t that because the Japanese government banned firearms and had an ongoing trade embargo to stop foreigners from coming over to sell them?Samurai and cowboys existed simultaneously for a period of time
this is only tangentially relevant to the conversation but its a fact that makes me happy
