[@BCTheEntity] As an alternative to guns, you might reference the sounds of low industry machines. A gravity drill. The rattling of a bellows driven by a mill, with the source of power being wind, water, or beast should suffice. Or even the sound of a burning warehouse full of barrels of lamp oil. Most of the could produce sounds similar to what you're looking for and don't require that guns exist, just in case Orior decides not to include them in this RP for some reason.
