An oil with a strong sulferous smell
Tapped from the bubbling black springs in the Karegia Islands, Kargegia Oil is an unholy mix of sulphur, black oil, and finely ground peat. When mixed in the right proportions, the oil will burn with a resilient blue flame. Hot enough to set all other flammable objects alight. Storing the oil is difficult for it is corrosive enough to leech through clay and burn through wax over time. It must be kept cool, preferably in water so that the noxious stench is reduced and the chance of a crack or a spill does not cause the whole lot to go up in a giant earth-shattering kaboom!
