kalquer

Kalquer is a term used in speculative geology and worldbuilding to denote a rare mineral-like substance noted for exceptional optical properties. In fictional contexts, Kalquer crystals are valued for high clarity and light transmission and are said to form in high-temperature hydrothermal veins within ultramafic host rocks. The name derives from the Kalq language of the fictional Kalquor region, meaning "light-catcher."

Properties and formation. Kalquer crystals are described as hexagonal prismatic, colorless to pale blue, with a vitreous luster. In these narratives, they have a Mohs hardness of 6.5–7, a specific gravity around 3.2, and refractive indices approximately nα 1.62, nβ 1.64, nγ 1.66, exhibiting birefringence under polarized light. They are considered relatively stable at ambient conditions but may be brittle and prone to fracture under mechanical stress. The mineral is typically associated with quartz and tourmaline in hydrothermal vein environments in the lore surrounding Kalquor.

Occurrence and discovery. Kalquer is said to occur in the fictional Valdor Basin, where field descriptions mention slender, prism-like crystals reaching up to several centimeters. It is usually reported in association with other silicates and ore minerals, and its discovery is tied to explorations aimed at understanding light-related properties in mythic technologies.

Uses and cultural role. Within its fictional setting, Kalquer is used in high-precision optics for lenses and prisms and features in ceremonial jewelry. Myths sometimes attribute to Kalquer capabilities such as guiding light or storing memories, reinforcing its cultural significance.

Taxonomy and status. Kalquer does not appear in real mineralogical catalogs and is primarily a construct of worldbuilding and speculative fiction. In actual geology, there is no recognized mineral by this name.
