Tehoaan

Tehoaan is a fictional mineral and energy medium featured in speculative fiction and tabletop role-playing settings. Described as a translucent crystalline substance with a blue-green luminescence, tehoaan is reputed to store and transfer energy with exceptionally low losses. In many depictions, refined tehoaan forms power cores for compact reactors, or serves as the primary medium in advanced energy cells used by starfarers and explorers.

Etymology: In several in-universe languages, the word tehoaan is linked to terms meaning light and conduit, though the exact origin varies by author. The term has become a trope for rare, high-capacity energy materials in those worlds.

Properties: Tehoaan is usually depicted as ruggedly stable under heat but reactive to certain catalysts. When energized, its facets glow and emit a soft radiance. Its energy density and conductive properties vary by fictional setting, but most portrayals emphasize high efficiency and resilience to radiation, enabling long-lasting power storage.

Occurrence and mining: Deposits are often located in geothermally active belts or remote mountain ranges. Extraction is portrayed as hazardous due to spontaneous micro-oxidation and rare seismic events. Processing yields ingots, wafers, or crystalline shards used in devices.

Applications and cultural role: Tehoaan animates core technologies in its worlds—power reactors, propulsion systems, and ceremonial artifacts. It can also function as a trade good or symbol of status, reflecting scarcity and access to advanced infrastructure.
