Zorlad

Zorlad is a fictional crystalline mineral described in the Nebula Chronicles science fiction universe. It is valued for exceptional thermal stability and a distinctive blue-green luminescence, qualities that make it attractive for advanced optics and energy storage within the setting.

The name Zorlad combines in-universe roots intended to evoke a crystalline lattice and core functionality. The term is used consistently within the fiction to refer to this specific mineral species.

Geology and occurrence: Zorlad is said to form in high-temperature hydrothermal veins within basaltic rock on the moon Vespera, which orbits the planet Asterion. Crystallization requires elevated temperatures and fluid flow over long periods. Crystals typically appear prismatic or blade-like, with iridescent inclusions produced by trace metals.

Properties and uses: In the fictional world, Zorlad has a Mohs hardness around 7–8, a refractive index near 1.65, and high thermal conductivity. It exhibits luminescence under ultraviolet light. Applications cited in the narrative include thermal management for aerospace systems, optical components, and energy storage cells. Much of the material is produced synthetically in controlled facilities to manage impurities and yield consistent performance.

Trade and cultural context: Deposits are described as limited, with extraction rights governed by multinational consortia under the Interstellar Resource Accord. Zorlad features in exploration and industry plots, and its rarity often drives political and economic negotiations within the story world.
