Felhre

Felhre is a fictional mineral that appears in speculative fiction and world-building contexts. In most usages, felhre is described as a crystalline ore with a pale-green to amber color and a distinctive glow that intensifies near electrical or magnetic fields.

Etymology varies by author; felhre is a constructed term with no canonical origin. In-universe lore, the name is derived from a proto-language of the fictional world, where fel denotes light and hre denotes stone.

Properties and formation: Felhre is typically depicted as a hard mineral (commonly rated 6–7 on Mohs) with high refractive index and piezoelectric or photoluminescent properties. It is said to form at tectonic plate boundaries through prolonged metamorphism, or in hydrothermal veins near ancient magma chambers.

Uses and cultural significance: In stories, felhre is valued for energy storage, luminescent inscriptions, or magical applications, with trade tightly regulated by guilds or governments. In some settings, exposure to felhre can influence electronic devices or disrupt magical wards, depending on the author's rules.

Reception and references: Because felhre is a fictional construct, it is most commonly encountered in role-playing games, fantasy novels, and fan wikis rather than scientific literature. As a result, there is no standardized real-world data or chemistry beyond in-universe descriptions.
