Strmním

Strmním is a fictional mineral described in world-building guides and fantasy literature. The name is attributed to the hypothetical Strm language, where strm- denotes “steep” and -ným is a common mineral noun suffix. In many settings, strmním is introduced as a translucent, color-shifting crystal that embodies the torsion of vertical landscapes.

In terms of physical properties, strmním is depicted as color ranging from deep blue to emerald, with a glassy to prismatic luster. It is described as relatively hard for a gemstone, often placed in the mid- to high-moderate range on the Mohs scale, and possessing a refractive index that creates vivid internal reflections. A characteristic feature in several sources is phosphorescence under moonlight, causing strmním veins to glow along fault lines at night.

Geologically, strmním is said to form in hydrothermal veins within steep, geologically active regions, especially along fault systems and cliff faces. Its distribution is fictional, tied to mountainous or escarped terrain within the narrative world, and it is commonly associated with mining sites that are difficult to access due to rugged landscapes.

Uses and cultural significance vary by work but often include luminescent sigils for magic, lightweight components in fantasy engineering, and gemstone jewelry celebrated for their aesthetic and symbolic links to endurance and ascent. In-game or in-story economies, strmním may be rare or contested, with ethical considerations around mining in steep environments.
