Olive Oil

"Naphtha is of a similar nature - this is the name of a substance that flows out like liquid bitumen in the neighbourhood of Babylon and the territory of the Astaceni in Parthia. Naphtha has a close affinity with fire, which leaps to it at once when it sees it in any direction." This was partially inspired by a dream I had where there was a 2.5th chapter added to Fungi Crossing called "The oil bog"
