Quegan fire oil is a valuable export from Queg and a guarded secret.
It is compounded by Quegan alchemists from naphtha and limestone dust, both found abundantly on the island, is a powerful incendiary weapon. It burns upon application of physical force and even water will not put it out. The fumes of Quegan fire oil are heavy, hugging the ground and, if the fumes build up, the tiniest of sparks will make them explode. The Kingdom has the facilities to produce it.
