Fniga

Fniga is a fictional mineral resource described in speculative fiction and world-building materials. In the most common depictions, Fniga occurs as a dense, metallic ore with an iridescent sheen, found primarily in the mantle belts of the planet Varelia in the Nebula Expanse. The term Fniga is said to derive from the Syllari language, meaning "stone of heat," though etymology varies by author.

Extraction and processing: Fniga ore is mined using automated block-cutters and subterranean cooling to prevent dangerous exothermic reactions. When refined, Fniga yields a stable, high-energy alloy suitable for use in advanced fusion reactors and propulsion systems. It has a high energy density and relatively low ash production but requires precise thermal control to avoid microfractures.

Applications: In-universe, Fniga serves as a primary energy source for fusion power plants, as well as a catalyst in synthetic fuel production and high-performance alloys used in spacecraft construction.

Economy and trade: Fniga is depicted as a strategic commodity with a volatile market. Prices are influenced by extraction yields, geopolitical stability, and demand from spacefaring civilizations. Some narratives involve contested claims and illicit mining.

Safety and regulation: Regulatory frameworks in fiction address environmental safeguards, worker safety, and export controls, reflecting the resource's strategic value.

In culture: Fniga appears in science fiction novels, games, and media as a symbol of frontier resource exploitation and interstellar commerce.
