Fäzes

Fäzes is a fictional mineral widely used in speculative fiction set in high-technology fantasy worlds. There is no single canonical definition, but it is commonly described as a rare, luminous crystal that blends scientific and magical properties. Etymologies vary by author, but several works attribute the name to an ancient word meaning light-binder or to the discoverer Fäze.

Fäzes crystals are translucent prisms that shift color from blue to violet in dim light and emit a soft glow. In many depictions they have a silica-aluminate lattice enriched with trace metals, giving them electrical conductivity and energy-absorption qualities. Reported hardness ranges around 6–7 on the Mohs scale, with high thermal stability in fictional scenarios.

In fiction, Fäzes forms in hydrothermal veins within basaltic rock, usually in remote mountains or desert escarpments. Mining is hazardous due to unstable tunnels and the mineral's tendency to release energy if mishandled; extraction is typically controlled by specialized guilds or corporations.

Within stories, Fäzes powers advanced devices, sharpens sensors, and acts as a catalyst for spellcraft or techno-magical interfaces. Its rarity and provenance often drive political plots and trade routes, making Fäzes a sought-after resource across realms.
