Koullarnn

Koullarnn is a fictional mineral that appears in multiple speculative-fiction settings, including novels, tabletop games, and game sourcebooks. It is typically described as a rare, translucent crystalline substance with iridescent coloration and a lattice structure that supports efficient energy transfer. In many narratives, koullarnn stores and releases energy in controlled bursts, making it valuable for compact power cells, encryption modules, and ceremonial devices.

The name koullarnn originates from a constructed language used by several authors to evoke an ancient, otherworldly sense. Across different works, the spelling and pronunciation vary, but the core idea remains: rarity, exotic origin, and potential danger.

In-universe properties and uses commonly emphasize energy density, stability under radiation, and sensitivity to improper handling. Harvesting Koullarnn deposits is often depicted as dangerous, with strict regulations or guardians protecting yielding sites. Processing can produce hazardous byproducts if performed without specialized techniques. Economies and politics within these worlds can hinge on control of koullarnn sources, influencing trade routes, alliances, and conflicts.

Cultural significance and variants frequently appear as well. Koullarnn may symbolize memory, knowledge, or pact-making in artifacts and rites, lending it ceremonial importance beyond practical applications. Variants introduced by different settings include koullarnn shards, cores, and dust, each attributed with distinct handling requirements and capabilities.
