CWBP 2 : Era and Technology

Yea, but we can bend the rules some. Arquebus-es became pretty readily available during the renaissance, so we could say a few of the larger empire have managed to start incorporating them. It might also be fair to say that some places or people might have begun to construct engineering marvels like basic hydraulics, or cool pulley & gear assemblies. etc.

Actually you might be surprised. It depend on how sophisticated your devices are but they probably existed in that time.

And Idk if guns kill imagination but they kill people and a lot. That's more of a problem.
But firearms where only limited to elite infantry at that time. It take some time before you get a whole army to use mostly firearms. Even then they would only have 1 shot before recharging and they would end the fight in melee.
