Ellurendi

Ellurendi is a fictional mineral created for use in speculative fiction, world-building, and related media. There is no real-world mineral by this name recognized by geological authorities.

In the imagined taxonomy, ellurendi is a silicate-oxide mineral with a layered crystal structure. It commonly appears pale blue to violet and has a Mohs hardness around 6.5, with a measured density near 3.2 g/cm3. Its optical properties are described as high refractive index and notable dispersion, making it a sought-after material in certain narrative technologies and jewelry accents within its fictional universe.

Formation and occurrence in the fictional setting describe ellurendi as crystallizing from silica-rich fluids in high-temperature hydrothermal veins or in mantle-like environments under elevated pressures. It is often found with accessory minerals such as fluorite and cassiterite and may occur as granular aggregates or prismatic crystals. Local geology for ellurendi-rich regions is depicted as diverse, ranging from deep crustal zones to volcanically influenced belts.

Applications and significance in the story world include use as a ceremonial gemstone and, in some techno-themed contexts, as a component in optical devices or energy storage concepts due to its described optical properties. Cultural value varies by region, with some societies venerating it as a symbol of clarity and insight and others trading it as a high-value material for technology and ornament.

Etymology and distribution: the name ellurendi is presented as a compound from fictional roots, often attributed to regions named Ellura and Enda in its lore. In the narrative, deposits are described as located in the Celaline Belt along the eastern continent, though these details are part of world-building lore.
