Jármn

Jármn is a fictional metallic mineral commonly encountered in fantasy and science fiction settings. It does not correspond to any mineral found in real-world geology, but it is used as a plot device and material standard across various works. In these universes, jármn is typically presented as a dense, resilient metal with distinctive properties that set it apart from ordinary metals.

Descriptions of its physical properties vary by author, but many portray jármn as a blue-gray metal with a high lustre. Its hardness is often placed in the mid-to-high range on the Mohs scale, and it is said to resist corrosion and retain shape under extreme stress. Some portray it as capable of unusual energy interactions, such as magnetism, energy storage, or light emission, depending on the fictional system.

Fictional deposits of jármn are described in regions with strong geological or magical activity. Extraction is usually depicted as dangerous, involving stability hazards, volatile reactions, or protective wards. Provenance of jármn forms and refined alloys vary widely between works, and many stories restrict access to rare refined forms rather than raw ore.

In-world uses include advanced armor and weapons, high-strength structural components for ships or engines, and components in energy or magical conduits. Some narratives describe jármn as a catalyst or conductor, enabling technologies that surpass ordinary metals. The scarcity and cost of jármn often serve as political and economic drivers in these settings.

As a fictional element, its properties are defined by the needs of each story. Readers should consult the specific work for canonical details, as there is no single universal description of jármn.
