Curmus

Curmus is a fictional mineral described in speculative science fiction, tabletop role-playing games, and related media. In these contexts, curmus is valued for high energy density, luminescent properties, and stability under extreme conditions, making it a common plot device for advanced power systems and photonic devices.

Origin of the name and discovery: In the fiction, curmus was first described by field geologist Dara Voss during a survey of ultramafic belts dubbed the Curmus Range. The name is said to combine an old mining term cur and the suffix -mus, chosen for its resonant, mineral-like sound.

Physical properties: Curmus typically forms dark, iridescent crystals with a metallic luster. It has high density and a Mohs hardness around 7.5. It exhibits luminescence under ultraviolet light and shows stable performance across a wide temperature range. In the lore, its lattice supports electrochemical storage and reversible photonic interactions.

Occurrence and production: In fiction, curmus occurs in vein deposits within ultramafic basalt and peridotite complexes, often alongside magnetite and calcite. It can be mined and refined using high-temperature crystallization and oxidation control; synthetic curmus can be produced in laboratories via hydrothermal processing.

Applications: The primary uses in fiction are energy storage and compact power systems for spacecraft, armored suits, and remote sensors. Its luminescence provides signaling capabilities, and its optical properties enable light-based computing or communications in the story world.

Cultural impact and regulation: Curmus is portrayed as a rare, expensive resource with strategic importance. In many settings, its trade is controlled by merchants’ guilds or planetary authorities, and responsible handling is emphasized due to dust toxicity and radiation risks described in the fiction.
