Mendosh

Mendosh is a fictional mineral broadly used in science fiction and related media to describe a compact, high-energy substance that functions as both a power source and a trade commodity. Because it is a constructed concept, its exact properties differ from one work to another, but common elements include high energy density, stability under harsh conditions, and versatility in refinement for various industrial applications.

In most depictions, mendosh is mined on remote worlds or asteroids and transported in specialized containment to protect against spontaneous energy release. Refined forms—such as mendosh crystals, dust, or rods—are routed to power reactors on starships, planetary infrastructure, or energy weapons. Its perceived value often fluctuates with political control of mining regions, technological demand, and the emergence of substitutes or purification methods.

Etymology and in-world origin of the term vary between narratives. Some stories attribute the name to a legendary founder, while others treat it as an ancient term whose meaning has shifted across different cultures within the fiction. As a narrative device, mendosh enables authors to explore themes of scarcity, energy ethics, black markets, and corporate or governmental power over essential resources.

Notes and variations of mendosh appear across a range of media, from novels and short fiction to role-playing games, where it may be adapted to fit distinct worldbuilding rules. Although it has no real-world counterpart, mendosh functions as a recognizable shorthand for a heavyweight energy resource in speculative fiction.
