tehly

Tehly is a fictional mineral that appears in science fiction and fantasy settings as a rare, energy-dense material with unique physical properties. The term is not a real mineral and has no standing in scientific literature. In narrative uses, Tehly is typically depicted as forming under high-pressure, low-temperature conditions within outer-space bodies such as silicate-rich asteroids or frozen moons.

In most depictions, Tehly has a luminously metallic appearance, with a crystalline lattice that allows efficient storage of electrical energy and rapid energy release. It is described as having high thermal conductivity and stability across a wide temperature range, enabling use in advanced power systems and propulsion.

Tehly is usually said to be rare, located in remote mines or asteroid belts. Extraction requires specialized mining fleets and refined processing to avoid spontaneous energy release.

In fiction, Tehly-based devices power starships, orbital grids, and portable energy cores. It is often the subject of political and economic plots due to its strategic value.

The concept has appeared in various works, sometimes used as a metaphor for scarcity, technological dependency, or regional power dynamics. Some authors treat Tehly as a metaphysical material tied to fictional cultures or mythologies.
