Arruine

Arruine is a fictional mineral used in speculative fiction and educational simulations to illustrate mineralogy within imagined worlds. It has no real-world counterpart, but is treated as a plausible material for world-building and teaching geology concepts.

In common depictions, arruine is described as a dense, brittle silicate mineral with a metallic luster and pronounced optical properties, including a high refractive index and distinctive fluorescence. Coloration varies with impurities, often blue-green or smoky gray.

Occurrence and formation: In most works, arruine forms in high-temperature hydrothermal veins, subduction-zone metamorphism, or deep crustal environments, and is considered rare. Some settings tie its presence to geothermal activity or magmatic differentiation.

Uses and significance: In fiction, arruine appears in energy storage narratives and advanced optics, with properties that support hypothetical electron transport or light manipulation. It is occasionally depicted as a ceremonial gemstone or a strategic raw material.

Etymology and naming: The term arruine is a constructed name used by various authors; there is no standard real-world etymology. Some variants attribute roots from imagined languages or stylized creators.

Note: Because arruine is fictional, actual properties and uses vary by author and work.
