metrood
Metrood is a fictional crystalline material commonly depicted in science fiction and fantasy narratives. It is typically portrayed as exceptionally rare and highly versatile, enabling energy storage, propulsion, and strong yet lightweight structural components. In many portrayals, metrood combines metal-like strength with ceramic or glassy properties, showing high tensile strength, favorable density, and unusual thermal and electrical behavior. Some stories describe metrood as having superconductive or anomalous conductive properties under specific conditions, enabling compact power cores and rapid energy transfer.
In-universe origins vary by work, but metrood is often said to form in extreme environments such as
Applications in fiction span several high-tech domains. Metrood is used to manufacture starship hulls and reactor
As a fictional construct, metrood’s characteristics are defined by individual authors and worldbuilding projects, leading to
