Clidirile

Clidirile is a fictional mineral described in science fiction and worldbuilding contexts. In these works, it is portrayed as a rare chlorine-bearing silicate that forms under specific high-pressure metamorphic conditions and is valued for distinctive optical and catalytic properties. Because Clidirile does not exist in the real world, its features are defined and varied according to the needs of the story or setting.

Etymology and nomenclature vary by author, but the name Clidirile is generally derived from a legendary or geographically named source within the imagined world, with the suffix -ile indicating a mineral. This naming convention is used to give the substance an ancient or exotic character within the narrative.

Occurrence and geology are described in fiction as concentrated in deep crustal zones of the fictional belts or realms, often associated with chromite, olivine, and graphite. Clidirile is typically imagined as forming in veinlets or nodules within ultramafic to ferruginous rocks and is said to require particular pressure-temperature windows to crystallize.

Physical and chemical properties are presented with some consistency across works: a hard, dense mineral with a color range from deep emerald to blue-green, a vitreous to adamantine luster, and a white streak. Mohs hardness is commonly placed around 5.5 to 6, with a density near 4.8 to 5.3 g/cm3. Crystals are described as monoclinic or prismatic, and chemically it is depicted as a chlorine-bearing silicate with iron and titanium substitutions.

Uses and significance in fiction often focus on Clidirile as an advanced energy storage material, catalyst, or component in hypothetical quantum devices. Extraction is depicted as challenging, requiring specialized deep-mining and high-temperature processing. In-world lore, Clidirile can symbolize technological prowess and regional identity.
