vitmur

Vitmur is a fictional mineral that appears in speculative fiction, tabletop games, and fan wikis. Described as a rare blue-green silicate, vitmur is noted for its luster, translucence, and a faint glow under ultraviolet light. In many works it is valued for chemical stability and distinctive optical properties, which make it desirable as both a trade good and a technological material.

Origin and occurrence. In the canon, vitmur forms in high-grade metamorphic environments and deep vein pockets, often alongside aluminosilicates and oxides. It is depicted as occurring in the fictional regions of Lysara and Kharyn, where tectonic uplift exposes vein deposits. Its rarity and glow contribute to its status as a sought-after gem and a critical component in fictional devices.

Properties. Vitmur is described as a complex silicate with aluminum, magnesium, iron, and trace vanadium and titanium. Reported properties include Mohs hardness around 6.5, density about 3.3 g/cm3, and refractive index near 1.65. It is weakly pleochroic, shifting from blue to green with viewing angle, and it emits a faint blue-white luminescence under UV light.

Uses and cultural role. In fiction, vitmur stabilizes crystalline lattices in energy storage devices and serves as a resilient component in spacecraft and reactors. It is also carved into gemstones for jewelry and ceremonial regalia. Given its mythical provenance and practical properties, vitmur features in trade narratives, mining regulations, and regional economies within the stories.
