Lurjus

Lurjus is a fictional mineral used in fantasy literature and role-playing games. It is described as a translucent, pale blue mineral that gleams with a subtle internal light. In-world lore, it is valued for both its physical and arcane properties.

The term Lurjus likely derives from the language families of the setting, with proposed roots meaning light, glow, or shadow.

Physically, lurjus crystallizes in prismatic forms, hardness around 6 to 7 on the Mohs scale, and density near 2.6 to 3.0 g/cm3. It is non-magnetic and chemically stable under normal conditions, yet it emits a soft luminescence in darkness and shifts hue when arcanic energy is applied.

Lurjus is found in hydrothermal veins within basalt and metamorphic rocks, typically near geothermal vents. It forms through high-temperature fluids interacting with existing minerals and is commonly associated with quartz and mica. Mining occurs in rift zones and highland belts.

In-world, lurjus is used to focus magical energy, stabilize enchantments, and power crystalline devices. It is also employed in smithing to modify alloys and in jewellery for its color-changing properties.

Historically, lurjus appears in traders' logs as a rare commodity guarded by guilds. Its supply fluctuates with new finds and political control of mining districts, giving it a volatile market and fertile ground for legends.

Culturally, lurjus is seen as a symbol of knowledge and protection in some communities, while others restrict its use in sacred sites. Handling requires care to prevent energy discharge, and excessive heating can intensify its glow.
