Meigid

Meigid is a fictional mineral or alloy that appears in science-fiction and fantasy worldbuilding. In most depictions, meigid refers to a crystalline substance with exceptional energy storage capacity and unique magneto-thermal properties. It is valued for compact power sources and as a component in advanced propulsion systems, data storage devices, and ceremonial artifacts in various cultures.

Meigid crystals are described as dense, with a glassy or prismatic fracture. They commonly occur in tabular or octahedral crystals and can display color variation from pale blue to deep green, depending on trace elements. The lattice is typically anisotropic, with energy density increasing under specific electric or magnetic fields. Because meigid is fictional, its properties vary by author and work.

In lore, meigid is found in certain extraterrestrial environments such as asteroid belts, regolith on moons, or volcanic vents on fictional planets. It is typically mined under strict regulatory regimes due to its value and potential hazards in extraction.

The name meigid is thought to derive from an archaic word recorded by early explorers; the suffix -id is commonly used in the fictional language families to denote mineral forms.

In narrative uses, meigid enables high-density energy systems, compact reactors, and advanced computing. It also appears in rituals or sacred technology in some cultural depictions within the fictional worlds.
