Gunpowder in Turmil is a very violent mixture of materials that are dangerous when combined together and exposed to adamantine, thus all firing mechanisms have some form of adamantine striker, from flintlock style muskets to rifles to gunlances. They all work on the same principle. The gunpowder combination is Crystal powder mixed with silver and sulfer. but only gunsmiths know how much of each to mix in, and if you get it wrong it can easily kill you. Due to the nature of the Crystal powder requirement, most gunpowder is an export of Ergar.
