Kiivreid

Kiivreid is a fictional mineral widely referenced in speculative fiction and tabletop role-playing games. It is described as a dense, opaque crystal with an iridescent blue-green luster that shifts with viewing angle. In many source materials kiivreid exhibits high thermal and chemical stability and notable hardness, making it valued for industrial and arcane applications within those worlds.

Etymology and naming. The term kiivreid is a coined name used across disparate works; there is no single standardized origin in the canon. As a result, descriptions and spellings vary between authors and settings.

Occurrence and formation. In lore, kiivreid forms in hydrothermal veins within ultramafic or subduction-related rocks, often in remote mountain regions. Deposits are typically small but highly pure, appearing as prismatic crystals or compact masses.

Physical and chemical properties. Color ranges blue to green and it commonly shows a metallic sheen. Some sources note faint luminescence under ultraviolet light. Compositional details vary, but many depictions describe iron, silicon and trace elements such as chromium or vanadium.

Uses and significance. Kiivreid is valued for energy conduction, magneto-electric devices, and in some settings as a catalyst for magical or alchemical processes. It also appears in jewelry and ornamentation in several cultures within its fictional universe.

In worldbuilding practice, kiivreid often serves to illustrate scarcity, trade routes, and technological or magical specialization, with different sources presenting different facets of its properties and history.
