Rohy

Rohy is a fictional mineral that appears in science fiction and fantasy worldbuilding. In most settings, rohy is described as a luminous blue-green crystalline substance with exceptionally high energy density and stability across a wide range of temperatures. Its molecular structure is portrayed as hexagonal prisms that fluoresce when exposed to certain wavelengths, making it a conspicuous resource in many narratives.

Rohy is typically mined in mountainous or tectonically active regions and refined through specialized processes to produce energy cells or power cores. In-world economies, rohy trades as a strategic resource, subject to export controls, smuggling, and territorial disputes between rival polities. The scarcity and difficulty of extraction often drive political plots and technological development, including advances in safe handling, shipping security, and end-use technologies such as space propulsion or emergency power systems.

Despite its fictional status, rohy serves as a narrative tool for exploring themes of resource dependency, environmental impact, and equitable access to energy. Some authors depict regulations and ethics around rohy mining, while others focus on the scientific challenges of stabilizing rohy-derived energy without triggering hazardous byproducts.
