eyrum

Ey rum is a fictional mineral commonly used in science fiction and fantasy settings. It is described as a lightweight, highly conductive metal with exceptional resilience, combining low density with high strength and stability under extreme temperatures and radiation.

The term ey rum is a coinage of speculative writers, with various in-world spellings and symbols. There is no real-world chemical basis for ey rum, and authors treat it as a versatile material with a broad range of extraordinary properties.

In many depictions, ey rum forms in restricted geological environments such as deep planetary crusts near magma chambers or volcanic belts, where unique mineralization processes are imagined to occur. In narrative contexts, it is mined with advanced laser systems and refined through high-temperature processing to produce usable ingots.

Physically, ey rum is described as having high electrical and thermal conductivity, excellent fracture resistance, and stability under intense heat and radiation. Some stories even attribute room-temperature superconductivity to ey rum, though this remains a fictional premise rather than established science.

Uses for ey rum in fiction are varied. It appears in energy storage devices, superconducting components, starship hulls and armor, precision instruments, and high-end cutting tools. Its rarity and perceived superiority make it a valuable strategic resource in many narratives.

Markets and governance in ey rum economies are typically centralized or regulated by mining consortia, planetary federations, or traders’ guilds. Prices fluctuate with discovery, regulation, political shifts, and demand from advanced technologies.

In fiction, ey rum has served as a plot device across games, novels, and campaigns, illustrating the tensions between scarcity, innovation, and control of a powerful material.
