In order to try and keep swords are still the dominant weapon, I am making guns slightly weaker then they are in other genre's and in real life. Guns normally have some kind of blade attached to them to help balance against their melee rivals.
Mayhems guns are powered by and shoot out crystals charged with magical energy. Based on what spell is imbued in the crystal, the ammunition will have different effects.
Mayhem firearms are a new technology, and are hard to come across. They are now only being distributed to the military, and the thieves brave enough to steal from them. It is for the most part illegal for non-militia to carry guns.
The Gun showed here is Mischifs, which he stole in a raid. His gun was enchanted by one of the crews mages to release small explosive blasts when the bullets hit things. Crystal shards make for frightening shrapnel.
