Dohadu

Dohadu is a fictional term used in speculative fiction to denote a rare crystalline mineral with extraordinary energy storage and superconducting properties. In common depictions, dohadu forms deep within planetary crusts or cometary interiors and is found in small, highly variable nodules. The mineral is described as having a glassy luster, a bluish-violet hue, and a lattice structure that enables low-resistance electrical conduction and high energy density.

Because of its scarcity and strategic importance, dohadu mining often drives political conflict and ecological debates in the narrative worlds. In many stories, access to dohadu is restricted by licensing regimes, cartel control, or territorial rights, and extraction carries risks such as environmental damage or worker hazards. Some works explore ethical questions surrounding resource exploitation, indigenous rights, and the impacts of novel technologies that rely on dohadu.

Beyond its use as a substance, dohadu appears as a name for characters or factions in various settings and occasionally as a fictional location. The term is not based on any real mineral or scientific term and is used primarily as a narrative device to examine themes of power, scarcity, and technological advancement.
