fraasin

Fraasin is a fictional chemical substance used in science fiction and speculative media as a potent energy carrier, catalyst, or mysterious material. The term does not correspond to any real-world compound, and there is no established scientific definition outside of its appearances in fiction.

Etymology and concept vary by work. The name fraasin is often presented as a stylized, invented term, with authors offering different imagined properties and mechanisms. Because it is fictional, there is no single canonical formula or structure, and descriptions range from crystalline powders to energetic fluids or metamaterials.

In fiction, fraasin is typically described as having high energy density and stable storage at ambient conditions, while releasing energy readily under specific triggers or conditions. Some depictions emphasize luminescence, heat, or other sensory effects when fraasin is energized. Handling requirements are usually specialized, with emphasis on containment, shielding, or compatibility with particular systems to prevent dangerous reactions.

Applications and role in narratives vary. Fraasin is commonly used as a power source for spacecraft, starship reactors, or portable field generators, and occasionally serves as a plot device to enable rapid transmutation, field manipulation, or advanced technology. Its scarcity and value often drive trade, political power, and security considerations within fictional economies and interstellar borders.

Notes: Fraasin has no place in real-world chemistry, and references remain confined to fictional works. See also fictional materials, energy sources in fiction, and science fiction world-building.
