The ever popular "nebulous mid- to late-2nd millenium Europe" setting strikes again. It'd be kind of like a western author confusing the Sengoku period with the Meiji restoration. I
think the main inspo is Victorian England? What with the afternoon tea, the overall dress, the classism and the nobility shenanigans, but then you've got Elizabethan domes and pillars, German-esque half-timbered housing mixed with full-brick/stone buildings (mandated post-Great Fire and brick in particular REALLY kicking off around the time of the Industrial Revolution) on the streets, and then that Derringer which was designed in 1865 and entered production a year later.
But then, if it IS Victorian England, why is it all swords and magic? Forget muskets, paper-walled shotgun shells were already a thing by then. Soldiers and nobility should at least be carrying some form of firearm, not
bows and arrows. Nevermind the fact that in so doing we skipped like, CENTURIES of weapon development. From no gunpowder straight to flintlock and then to metallic cartridges, what a leap.
And even further, if firearm development is JUST NOW starting,
why is no one still wearing armor? Armor
eventually got obsolesced by firearms (that's kind of why you don't see it around anymore), but until that point, armor-clad knights were basically impervious to anything short of a longbow's arrow (and even then that depends on a lot of factors), a lot of blunt force or a very lucky strike. "Maybe they wanted to be more nimble to dodge magic!" A)
it's plenty mobile and B) on the off-chance you
do get hit, I know I'd rather have a steel plate (and presumably some chain and a gambeson) between me and a Fire Bolt or whatever.
...Hell, actually, on reread,
has magic ever been mentioned before now? Admittedly it was just a light skim but I never once noticed anyone casting a spell or any mention of magic. There are monsters, sure, but no fireballs, no mages, no casting system. Was there a mention of magic stones I just happened to miss? If yes, why aren't they... well,
everywhere, or at least slightly more present, and if no, there being monsters around is even more reason to wear armor.
