Firearms

The world of Kytheria blends gunpowder and magic, with the result being that pistols and rifles are somewhat common, but not the military game changers they might be on other worlds. The phalanx formations favored by the Republic and Jagged Sea areas incorporate bronze in their shields, allowing wizards to shield against most projectiles of a certain size with relative ease; a massed line of riflemen would be ineffective, and rifles in a phalanx are more commonly used when two units are pushing against each other and the shield of magic is broken. A soldier with a rifle standing behind the shield wall could push the barrel into the opposing formation and wreak havoc, with sharpshooters still useful and pistols for individual fighters or street fights more common. Another defense against firearms lies in specifically woven silk, capable of stopping bullets even from pistols at close range, making bullet-proof clothing a hot commodity among those wealthy enough to afford it. The result of this is that firearms have never undergone the intensive arms race that they have in our own history; single and double action revolvers and rifles are the current top of the line firearms, and there has been little incentive to create anything more sophisticated as bullets are expensive enough not to warrant being wasted. A dwarven engineer who suggested a gattling gun would be laughed out of the workshop, as one may as well design a machine that rapidly hurls silver coins at an enemy. 
Magic and war on Kytheria have also changed the need for things to be mass-produced. Unlike in our own history, the incentive to remove any capacity for craftspeople to weave magic into their goods hasn't existed, and though imperialism has certainly spread through empires in Kytheria from time to time, the specific conditions of Earth that concentrated so many raw resources into the hands of countries with technological adaptations that could ruthlessly exploit them haven't arrived. The elves are notorious for leading man'di armies against empires that rise too high, and dwarven pride in their own crafting and guilds prevents them from leaving such things up to a machine. One may as well design a robot to paint, by their estimation. This contributes to superior dwarven quality, and no human machine would ever compare, were they to make them. It's as if the gods have long conspired to keep industrial ambitions low.
Firearms therefore are always unique, even if a stock pattern is being used, and while they may conform to specific sizes for the barrel it takes dedicated smiths to craft such weapons. Little additional expense is necessary to customize these weapons and most smiths will add a little flair or decoration to the receive or butt stock, and take great pride in their work. Among some cultures, firearms are expensive enough that they're passed along as precious family heirlooms and might indicate inclusion in a specific noble rank.
In addition to what we would recognize as standard firearms, there exist numerous hybrid weapons (firearms as part of a melee weapon) which have met with varying degrees of success. Dwarves of questionable sanity developed such concepts as the Thunder Hammer, a heavy-headed weapon designed to fire a round into whatever it hits (and some frightening examples can hold a few rounds), though typically this hybridization means that a short sword will have a pistol attached, or a polearm my have a rifle built into it. Maintaining barrel integrity while swinging a weapon in melee is difficult and requires some pretty serious metallurgy, but a few smiths in history have proven up to the task.
The last firearm variant involves wizardry, and this is where firearms truly shine. Orichalchum rifles or pistols are oftne used byh wizards to focus their more devastating magic spells; tongues of flame or cruelly sharpened fragments of compressed and shattered air fly from these barrels with greater ease, allowing wizards to be more effective in single combat. Though useless in the hands of anyone who doesn't bear a Mark, these fearsome weapons can make a mildly annmoying wizard a deadly terror on the battlefield.
