Spelljammer-Adventures In Realm Space
Gun Powder, Blast Powder, Boom Dust. There are thousands of names for this material all over wildspace. Depending on the Crystal Sphere this substance might not always have the same applications and it is quite often attributed different secondary effects depending on the local deities, such as being water proof, colored differently, and even being magnetic or having magical effects.
However Gun Powder is generally a fine sand or dust like material that is flammable in nature, and tends to explode when in a controlled confined place, making it’s primary use being the function it has in firearms and explosives.
