Everything but the gunpowder is a go. Just claim a spot, pm it to Isotope, and pm me a sheet!
[/quote]We have literal magicians and alchemy. It may not be gunpowder but creating a simple explodey mixture is rather simple in comparison to anything else.
Guns are required exactly because they're so simple when we talk about primitive types. They can be created by people without extensive infrastructure unlike crossbows or anything similar.
Besides, I am a strong opponent of Fantasy Gun Control. It's ridiculous because firearms alone barely changed anything. It was a centuries long progress.
Any sorts of magical effect or item would shake up the world far greater than the existence of firearms ever would. It's also well-known that the majority of the classic middle ages was also the dawn of firearms. Eliminating one would bring down the another.
It's the preorgative of all players to decide what kind of weapons and other details they have so I of course won't force anyone but again, firearms of the early kind won't change zilch in the setting.
