Magnetteja

Magnetteja is a fictional mineral frequently referenced in speculative fiction, role-playing games, and worldbuilding narratives. It is not recognized as a real mineral by professional geological catalogs or scientific authorities.

The name Magnetteja is a neologism that blends the concept of magnetism with a mineral-sounding suffix, giving the term a plausible, ancient tone in fictional settings.

In most depictions, magnetteja is a dense metallic ore with ferromagnetic properties, capable of retaining magnetization at ambient temperatures. It is often described as silvery-gray, sometimes with a blue luster, and as brittle when worked.

Geological setting in fiction places magnetteja in hydrothermal veins or deep magmatic pockets, often alongside magnetite and other iron-nickel minerals. Its formation is typically tied to high-temperature, high-field environments.

Uses within storyworlds range from a source of strong permanent magnetism for machinery and weapons to a rarified material valued for trade or ceremonial purposes.

In published worldbuilding compilations, magnetteja often serves as a plot device to explore resource shortages, technological leaps, or geopolitical tensions centered on access to rare minerals.
