attraho

Attraho is a fictional mineral that appears in speculative fiction and world-building contexts. It is described as a dense, luminescent crystalline substance that stores large amounts of energy per unit mass and serves as a common plot device in technothriller and science-fantasy settings. The name is of invented origin, drawn from sound symbolic roots in several created languages.

Attraho is depicted as hexagonal prismatic crystals with a deep indigo color that glows faintly when exposed to ultraviolet light. In most works, its hardness is given around 6.5 on the Mohs scale, and its density near 3.9 g/cm3. It exhibits high electrical conductivity and unusual quantum-optical properties, enabling room-temperature superconductivity in some speculative devices. Its stability improves at elevated pressures, and it can become transiently magnetic under certain thermal conditions.

In-universe deposits are described as rare nodules forming in ultrahigh-pressure metamorphic zones, typically associated with deep crustal subduction analogs. Attraho is mined from subterranean pockets or seafloor vents using specialized drilling and dredging equipment. Refining processes reportedly convert raw ore into a usable energy matrix and manufacturing-grade alloy stock.

Used as a high-density energy store and as a catalyst in experimental quantum devices, attraho's scarcity promotes geopolitical competition over mining districts and processing facilities. The term is tied to a fictional language family where attr-"light" and -ho-"core" are components.

Real-world note: Attraho is a fictional construct and not recognized by real-world geology or materials science.
