Hello,
This is something I have thought about, crafting explosives. You know guns, gunpowder, bombs, and so on. This would work for Alchemy and Blacksmith, they can work together. For example, Alchemy can create gunpowder and a black smith can forge the gun/ammo. This would allow Dementlieu to have PC gunsmiths and explosive makers, allow gundarakite rebels to use them, and so on. I think this would add to the setting by making explosives and guns craft able, with the resources findable mostly in dementlieu.
I would like to hear what others think of this idea,
