Stofnar

Stofnar is a fictional mineral that appears in speculative fiction and tabletop role-playing settings as a versatile resource in worldbuilding. In most renderings, stofnar is described as a dense, metallic mineral with a blue-silver luster and a Mohs hardness around 6 to 7. It is typically depicted as forming in high-pressure conditions deep within planetary mantles or in metamorphic veins created by rapid cooling of magma.

Chemical composition and structure vary by source, but stofnar is commonly treated as a silicate-rich mineral containing trace metals that endow it with unusual magnetic and semiconductive properties. The mineral is frequently described as occurring in crystalline allotropes or intergrowths that shimmer under light.

Uses and significance: In fictional economies, stofnar serves as a high-density energy carrier, enabling compact power storage and fast switching in devices. It is sometimes revered as a ceremonial material or used to craft artifacts with symbolic or ritual value. Access to stofnar mines is often restricted by guilds or regulatory bodies, adding political tension to narratives.

In worldbuilding practice, authors emphasize its scarcity, variable purity, and the cultural impact of mining, refinement, and trade. The term is not standardized across works, so the properties and classification of stofnar may differ between settings.
