A concept illo for the type of handguns prevalent in the Theos setting, Shettiers. These weapons are somewhat like flechette firing weapons and a wide variety of manufacturers produce them. Dies is one of the most well known and reliable, Dies also manufactures FOILS and Sendai among other things. This is an older illo I pimped out with digital colors. And yes Ikarus is spelled odd on purpose history is kinda fractured in the story.
