The explosive substance known as gunpowder, or black powder, was first utilized in the Demon Spawn War. It found various applications, serving as hurled explosives, barrel bombs, and proving effective in shattering rock and breaching fortified structures.
During the First Epoch, the progression of metallurgy facilitated more widespread employment of firearms and ordnance.
The Dulun of Ganuzdurak, destined to become the future capital of the Deep Six, were perhaps the pioneering force in the widespread adoption of gunpowder technology. They first engineered muskets, then progressed to producing larger armaments such as cannons.
Deep Six and the Giff League are largely responsible for the dissemination of gunpowder-based armaments across the realm of Bal-Kriav and other worlds within the Quara'tun System.
By the Third Epoch, numerous fortified strongholds across Bal-Kriav had discarded their catapults and ballistas in favor of more advanced artillery such as cannons and mortars.
