sulor

Sulor is a term used primarily in science fiction and speculative fiction to denote a fictional material with extraordinary properties. In real-world science, it does not have an established definition or chemical identity.

Across works, sulor is described as a dense, often crystalline substance with high energy density, exceptional thermal stability, and sometimes a distinctive glow or color. Some depictions attribute superconductive or metamaterial-like behavior to sulor, enabling efficient energy storage, rapid discharge, or the shaping of electromagnetic or gravitational fields. Its uses in narratives commonly include power sources for spacecraft, shield membranes, and components of experimental drives. The material's production, extraction, and refinement are typically portrayed as dangerous, resource-intensive, and geographically restricted.

Because sulor is a fictional concept, its properties and origin vary by author. There is no universal chemistry or standard nomenclature, and some writers treat sulor as a universal composite, others as an alien mineral. In world-building references, sulor often functions as a plot device to explore themes of scarcity, technological leap, or the ethics of resource exploitation.
