Blackpowder on the Coin

Gunpowder, more commonly known as blackpowder, does exist on the Coin, although it's use is as yet not widespread. It gets used for all the various things it got used for in our own history, such as guns, cannons, bombs, fireworks, and the Xingian Flamethrower.... but it is also used by trolls as a hard drug, typically inhaled through the nose. The rocky consistency of the trollish metabolism can occasionally cause sparks, which is turn means that troll blackpowder addicts run the risk of spontaneous cranial explosion. This explains why they are often referred to as "crackheads".
