Serpentine Light

Concoction 738 'Serpentine Light'. Developed in 1590 by the Jade Fang Empire's military research branch, this green-tinged oil has properties of kerosene. When burned the oil generates a green-hued fire which produces a warmth similar to basking in the sun. The strategic value of this new heat source was immediately seen in the eyes of the military, and mass production was ordered soon after testing concluded. The ever-present eerie green glow of its fires became synonymous with the Great Serpentine Wall from which it derived its name from.

The Serpentine Light is very stable, to the point of being nearly inert. This oil requires the usage of magically reinforced igniters and vessels to burn within. These vessels take the form of small lanterns to large braziers, the latter allowing an entire encampment of soldiers to be bathed in its warming light. The slow burning nature of this oil results in a single brazier being able to stay lit for an entire day. This greatly reduces the logistical burden of the military, a single gallon replicating that would traditionally have taken multiple cords of wood to achieve in heating.

Serpentine Light is typically moved in massive drums made of a silver-laden alloy, the silver preventing long-term degradation of the oil. In camps it is common to see the fluid distributed in ornate silver pots, each unit having their own unique designs. The superstitious amongst the soldiers believe throwing gold coins into the flames as a gift to Greed will result in a brighter burn.
