Évekbl

Évekbl is a fictional crystalline mineral that appears in speculative fiction, tabletop settings, and world-building projects. Described as transparent to pale blue, it is said to form in secluded metamorphic terrains and hydrothermal veins, often under conditions associated with rapid geological change and mantle-derived fluids.

Etymology: The word évekbl is constructed for narrative use; in most universes the name is linked to time-related or stratigraphic imagery. Writers frequently interpret the term as implying a "time shard" or "layered memory."

Properties: In the fiction, évekbl crystallizes in hexagonal or trigonal habits, forms tabular to scalenohedral crystals, and has a Mohs hardness around 6.5. Reported densities cluster near 3.2 g/cm3. It is often described as pleochroic, shifting from pale blue to indigo, and it may exhibit faint UV luminescence and weak piezoelectric effects.

Occurrence and formation: Évekbl is commonly associated with quartz, muscovite, and hematite in hydrothermal veins and high-grade metamorphic rocks. Its formation is attributed to rare combinations of heat, pressure, and trace elements such as vanadium, with crystallization linked to episodic uplift and fluid flow.

Uses and significance: In narrative contexts, évekbl serves as a plot element for timing, memory storage, or energy resonance. In game settings, it may power artifacts or act as a rarity tied to factional lore. Its value depends on color, stability, and luminescent properties.
