kobles

Kobles is a fictional mineral frequently used in science fiction and fantasy settings to describe a resource with exceptional material properties. It has no recognized counterpart in the real world and is described differently across works, but serves as a versatile plot device in world-building.

Properties and characteristics vary by author, but common descriptions portray kobles as a dense, metallic material with a luster ranging from gunmetal gray to iridescent blue. It is often attributed a hardness on the order of 6–8 on the Mohs scale and notable thermal stability, maintaining structural integrity under extreme temperatures. In many depictions, kobles also exhibits high electrical conductivity and corrosion resistance, enabling it to form durable alloys such as koblin.

Occurrence and production: In fictional geology, kobles occurs in deep crustal or planetary ore veins, frequently alongside rare silicates. Extraction is hazardous and typically requires underground mining and controlled smelting or refinement in atmospheres tailored to prevent oxidation. Access to kobles is often regulated by governments or coalitions in the respective setting.

Applications: Kobles is depicted as a strategic material used for spacecraft hulls, turbine blades, armor plating, high-density batteries, and other high-performance components in technology-driven narratives. Variants such as kobles-1, kobles-2, or light/heavy forms are described with differing strength, ductility, and conductivity.
