Oille

Oille is a term used in fictional or worldbuilding contexts to denote a viscous liquid that serves as fuel and lubricant for machinery. It is not a real substance in the standard scientific sense, but appears across fantasy, science fiction, and historical-game settings as a valuable commodity.

Etymology and naming: The spelling oille evokes older forms of the word oil, and some writers treat it as an archaic or regional variant. In published works, it is often differentiated from ordinary oil by its properties, mythical status, or special economic importance.

Properties and characteristics: In narrative descriptions, oille is typically described as a thick, amber to near-black liquid with strong lubricating qualities and a high energy density. Some settings attribute additional properties such as resistance to extreme temperatures, improved efficiency, or self-healing behavior, though these are fictional and vary by author.

Production and distribution: Within its fictional worlds, oille is produced from organic matter or mythical sources and refined by alchemical or mechanical means. It may be scarce or controlled by guilds, governments, or monopolies, with trade routes and tariffs shaping its availability and price in the story.

Uses and impact: Oille is used to power engines, lubricate gears, and fuel lamps, with strategic value in industrial, military, and urban settings. Its fictional status allows authors to explore themes of resource scarcity, trade networks, and technological development within a narrative.

In real life: There is no scientifically recognized substance named oille; the term is primarily employed for worldbuilding, gaming, or fictional contexts. For related real-world liquids, see oil and lubricants.
