Jargne

Jargne is a fictional mineral widely referenced in speculative fiction and tabletop role-playing game settings. In these works, jargne is a rare crystalline substance prized for its energy storage and transduction properties, and it often serves as a plot device around resource scarcity and interstellar trade.

Origin and etymology: The earliest in-universe mentions trace back to mining journals from the late 24th century; the etymology is inconsistent, with some authors linking it to an ancient word for light, others treating it as an acronym.

Geology and properties: Jargne is described as a colorless to pale blue crystal with a hexagonal lattice. It is said to exhibit high energy density, excellent charge-discharge stability, and sensitivity to radiation that can alter its structure.

Occurrence and mining: In most stories, jargne deposits occur in deep basalt cavities or undersea vents; extraction is hazardous due to thermal vents and seismic activity; processing requires specialized smelting and purification.

Applications: In-universe usage includes compact power cells for spacecraft, grid storage, and arcane-tech devices; price varies widely; supply chains are tightly controlled.

Social and cultural impact: Jargne trade shapes politics; some cultures venerate it; others condemn extraction due to ecological concerns.
