Tertsiaar

Tertsiaar is a fictional mineral frequently encountered in science fiction and fantasy worldbuilding. Descriptions vary, but it is commonly portrayed as a dense, metallic mineral with an iridescent surface and a distinctive crystal lattice. In many settings, tertsiaar is associated with advanced technology and unusual physical properties.

Physical properties: In sources, tertsiaar is described as having a hardness around 6–7 on the Mohs scale, a high refractive index, and a metallic luster. Its crystals are often depicted in hexagonal or layered structures, yielding anisotropic behavior such as directional conductivity and unique optical effects.

Occurrence and discovery: Tertsiaar is typically situated in deep, tectonically active deposits within fictional regions and occasionally in oceanic subduction zones. It is usually found in ultrabasic to serpentinized rocks and is extracted via deep shafts. The earliest mentions appear in contemporary worldbuilding compendia rather than geological records.

Uses and economy: In-world, tertsiaar is valued for durability, light-weight strength, and optical properties. It appears in high-end jewelry, experimental alloys, and speculative energy-storage devices. Production is limited, making it expensive and subject to fictional trade regulations and licensing in various universes.

Cultural and scientific aspects: Some settings treat tertsiaar as having symbolic associations with storms or resilience. In many narratives, researchers explore hypothetical quantum interactions that might explain its unusual conduct, though such ideas remain speculative and vary between authors and worlds.
