I’m actually thinking about including this in my current worldbuilding project. In my universe, dwarves have a particular talent for enchanting magic, runes and wards. This allows them to create advanced pieces of machinery that would otherwise be impossible.
They use this magic to create a dedicated headgear for their musketeers, which includes hearing protection, flash protection, air filtering, and enhanced night vision. There’s a whole sub-story about those headgears evolving into basically power armors over the decades, to the point that they eventually become too over-enginereed and expensive to be actually viable in warfare.
In addition, after a certain point in development, only mages could actually use those armors. This led to the muskets being modified to channel magic too, thus they couldn’t be used by a normal dwarf anymore either.
My world is more in a Pike and Shot era militarily speaking, as there isn’t magic capable of blowing up formations, artillery is still too primitive to do a lot of damage, and magic beasts like dragons maintain the usefulness of dedicated pikemen formations.
In ebil China, people are forbidden from learning about the crimes of their government…
Thankfully we don’t have that kind of brainwashing here !
