Fundarins

Fundarins refers to a fictional mineral or crystalline substance used in various science fiction and fantasy settings. It is not a real material, and there is no canonical definition across sources. The exact properties and role of fundarins differ by work, but several common motifs recur: fundarins are rare, hard crystals that form in deep geological settings or in meteorite impacts; they exhibit bright, shifting iridescence and are described as having resonance with energy fields or magic.

In many narratives, fundarins function as a highly efficient energy storage medium or conductor, enabling advanced devices, starship reactors, or portal mechanisms. In other depictions, they serve as a tradeable commodity, valued for rarity or for ceremonial or ritual significance. Crafting or extraction is often depicted as dangerous, requiring specialized equipment or knowledge.

Origin of the term is informal; authors and game designers have created their own lore. In fan communities, fundarins are sometimes used as a generic placeholder for any rare crystalline resource. Some settings treat fundarins as a living or semi-sentient material with unique behavioural traits in response to resonance.

Because fundarins are not a real material, references are confined to fictional texts and game manuals. When encountered outside of fiction, the term may be used metaphorically to denote something precious and scarce.
