Hefwiel

Hefwiel is a fictional mineral that appears in speculative fiction and world-building discourse. In most depictions it is described as rare and exceptionally hard, with high thermal stability and a faint blue glow that emerges in darkness.

The name hefwiel is a constructed term, drawn from invented linguistic roots rather than any real language. In published world-building materials, it is capitalized as Hefwiel when treated as a proper noun.

Geologically, hefwiel is said to form under ultra-high-temperature metamorphic conditions and is commonly found in quartz-rich veins. In many stories it is associated with the mountainous regions of the fictional continent of Novera.

Properties and uses: Reported hardness around Mohs 8, strong resistance to corrosion, and luminescence; applications in narratives include durable toolmaking, armor components, and prototype energy-storage devices developed by fantasy civilizations.

Cultural context: Hefwiel figures in myths about endurance, light, and discovery. The earliest in-world reference is the Chronicles of Eldor (dated circa 4500 AR in some canons). Real-world discussions of hefwiel occur only within fictional literature and game-world documentation.
