Oil

"The lantern sputters as the tallow burns low, casting greasy shadows on the stone walls. The air stinks of old meat and smoke—common light for a common place."
——From the field journal of Ser Damaric Vann, Knight of the Ashen Lost

A thick, slow-burning liquid used to sustain fire in lamps, lanterns, and torches. Typically rendered from animal fat or coarse plant oils, this fuel is cheap, smoky, and pungent—but vital for survival in the dark. Whether lighting a camp, exploring forgotten ruins, or keeping watch through the long night, even a small vial of oil can ward off darkness for hours. Though messy and foul-smelling, it's a staple of every adventurer's pack.

Though not intended for consumption, common oil—especially when derived from rendered animal fat—can be eaten in dire circumstances. Thick, greasy, and foul-tasting, it offers little in the way of satisfaction, but it is calorie-rich and can stave off starvation. A single pint contains enough fat to sustain a person for two to three days, though it provides no hydration, vitamins, or protein. Consuming it too quickly may cause nausea or digestive distress, making it a last resort for the truly desperate.
