That's why my idea is so brilliant. Two mages, one working on a fleshlight and the other working on a crossbow, they look at each other's work, and bam! pistol grip on a fleshlight.I don't think that would happen. The world seems to be around a mid-late phase Bronze Age, and while there are examples bronze cannons in our world (the Chinese Huochong comes to mind, with the earliest dating back to 1298), I don't think the world of Savarra is up there yet.
Besides which, early firearms were difficult to make, and especially as Savarra can't make steel (not that steel is a requirement for the production of firearms, there are certain aspects of chemistry and the like that would needed).
And anyway, any sort of firearm would be a rare instrument, akin to a magical relic and overpowered as fuck.
