Druenge

Druenge is a fictional mineral term used in fantasy literature and role-playing games to describe a translucent, luminescent crystal that interacts with magical energies. Within the imagined worlds where it appears, druenge glows with a cool blue or greenish light and can absorb ambient magical currents, later releasing them as a controllable glow or concentrated energy pulse. The name is generally considered to derive from invented languages in those settings, with no real-world etymology.

Physically, druenge is described as glassy to crystalline in habit, often with a faint iridescence and a hardness sufficient for crafting in jewelry and arcane apparatus. In many texts it is worked into runestones, focus lenses, or energy conduits; when cut and aligned, it is said to improve stability and efficiency of magical devices. Handling druenge typically requires care, as improper cutting or heat can cause it to fracture or leak stored energy.

In-world sources locate druenge mainly in remote mountainous regions and volcanic belts, where it occurs as pockets within basalt or granite. Economically and culturally, it can serve as a luxury material, a form of currency, or a ritual object depending on the setting. Some authors use it as a plot device central to power struggles or to signify legitimacy for rulers or guilds. Different settings may give druenge varying properties or limitations, such as sensitivity to heat, charge thresholds, or ethical considerations regarding extraction.

Overall, druenge functions as a versatile fictional element that intersects magic, technology, and culture within its narratives. Druenge is a fictional construct and should not be treated as a real mineral.
