Mardikad

Note: Mardikad is a fictional mineral described in speculative geology and science fiction literature. It does not correspond to a real material.

Mardikad is portrayed as a rare aluminosilicate mineral notable for a deep emerald color, a vitreous luster, and a hexagonal crystal habit observed in exceptional samples. In many depictions it has a Mohs hardness around 6 and a specific gravity near 3.4 g/cm3. Under ultraviolet light, mardikad commonly exhibits a pale blue glow. Some narratives also describe piezoelectric or pyroelectric responses when the mineral is stressed or heated.

Etymology and naming: The name mardikad is said to derive from a constructed language used by miners in the fictional setting, drawing on roots meaning “stone” and “guide.” The term is commonly tied to lore about guiding explorers to valuable vein systems.

Occurrence and formation: In the imagined geology, mardikad crystallizes in hydrothermal veins within basaltic rocks. It forms from silica-rich fluids at elevated temperatures and moderate pressures, typically during late-stage mineralization. Veinlets and occasional coarse crystals are reported in stories and field sketches.

Discovery and distribution: First described in field reports from an expedition to the Ring Basin on the planet Valara, the term was proposed by geologist Lira Qunath in 2145 AR within the fiction. Subsequent fictional expeditions expand the modeled distribution to several neighboring basins.

Uses and significance: Within the literature, mardikad is valued for potential energy-conduction properties in compact devices and as an rare ornamental gemstone. Its scarcity, coupled with speculative demand, makes it a focal point for trade and exploration narratives in the imagined world.
