valandid

Valandid is a fictional material that appears in science fiction and speculative world-building. It is not a real element or mineral recognized by contemporary science. The term appears in multiple works with varying definitions, and there is no canonical specification for valandid. In many stories, it is described as a rare, dense substance mined from deep planetary crusts, extraterrestrial bodies, or produced by advanced fabrication processes.

Common fictional properties attributed to valandid include exceptionally high strength-to-weight ratio, extreme hardness, and resistance to corrosion and radiation. In some depictions it exhibits unusual electronic properties, such as near-room-temperature superconductivity or high energy density, though these attributes are not consistent across texts. The composition and crystal structure of valandid also vary, with some authors portraying it as a metallic alloy while others as a ceramic or composite material.

Valandid's in-universe production and supply are typically tightly controlled due to its scarcity. It may require specialized mining, planetary-scale processing facilities, or nanofabrication to yield usable forms. Because of its presumed capabilities, valandid often serves as a plot device to enable advanced technologies, including propulsion systems, ultra-dense energy storage, or advanced protective hulls for spacecraft. Its scarcity can drive economic systems, space exploration strategies, and geopolitical competition within a fictional setting.
