Gruplandrma

Gruplandrma is a fictional mineral term used in speculative fiction and world-building contexts. In those works, gruplandrma is described as a rare hydrous silicate with luminescent properties and notable energy storage potential. It is typically associated with deep-sea hydrothermal vent environments and high-pressure metamorphic belts, where mineralogical inclusions create distinctive crystal structures.

Physical properties commonly attributed to gruplandrma include tabular to blocky crystal habits, a vitreous to subadamantine luster, and a color range from pale emerald to cobalt blue. Reported hardness is around 6 on the Mohs scale, with a density near 3.2 g/cm3. Under ultraviolet light, the mineral is said to exhibit blue-green phosphorescence, and its crystals can display anisotropic glow in filtered lighting.

Discovery and naming within the fictional setting place the first documented finds in the Ringar Subduction Zone during expeditions led by geologist Dr. Mina Koy in 2147. The name gruplandrma is described as a constructed term drawing on imagined linguistic roots that convey “light-binding,” reflecting purported energy interactions observed in the mineral.

In-universe, gruplandrma is valued for energy-related applications and as a gemstone. Proposed uses include efficient energy storage cores, lightweight superconducting components, and display materials due to its glow. Its rarity and geopolitical significance are noted in trade and regulatory contexts within the setting, contributing to its mystique in the story’s world-building.
