kjörgengi

Kjorgengi is a fictional mineral described in fantasy and worldbuilding literature. In most sources, kjorgengi is a translucent silicate with a vivid iridescent sheen that shifts through blue, green, and violet as the angle of light changes. It is highly valued in narrative settings for its beauty and light-refracting properties.

Geological setting and occurrence are described as forms of high-temperature hydrothermal deposition and metamorphic rock associations within the Kjorg archipelago and adjacent lands. In these depictions, kjorgengi commonly occurs with quartz, chlorite, and magnetite. Crystals are typically prismatic to tabular, ranging from a few millimeters to several centimeters in length.

Physical properties are given in fictional catalogs as a Mohs hardness of about 6.5 to 7, a refractive index around 1.70 to 1.75, and poor to indistinct cleavage. Specific gravity is usually noted near 3.2 to 3.6. These values are varied across different works, reflecting the mineral’s embellishment for storytelling rather than real-world measurement.

History and provenance within the lore trace the term to the Kjorg language family. The earliest fictional description often cited is from field notes by a character named Dr. Leora Inkborn, dated in the late historical arc of the setting. Over time, kjorgengi appears in various texts as a marker of wealth, artistry, and ceremonial significance.

Uses and cultural role center on jewelry and ceremonial objects. Its color play makes it a prestige material in trade networks and quest narratives, where wearing kjorgengi is sometimes linked to protection, enhanced vision, or connection to the sky deities, depending on the story. Etymology generally links the name to a word meaning rainbow and a suffix denoting stone.
