lüliid

Lüliid is a fictional mineral described in speculative fiction and worldbuilding. It is not a recognized substance in real-world geology, and no empirical data exists outside its fictional cosmology.

In the primary sources, lüliid is presented as a transparent to translucent blue-green crystal with a vitreous luster. Descriptions of its crystal system vary, and it is commonly depicted as hexagonal or prismatic. Its hardness is said to be comparable to quartz, with a moderate density, though these attributes differ among authors and worldbuilding universes.

Geologically, lüliid is said to form in high-temperature hydrothermal environments within basaltic or ultramafic rocks, often occurring in veins together with quartz, hematite, and magnetite. Its distinctive color and occasional luminescence are attributed to trace elements such as vanadium or europium in certain fictional narratives.

Etymology and naming reflect its status as a constructed element of a fictional culture. The term “lüliid” is traced to a made-up language and regional spelling conventions used by different fictional communities, which leads to slight variations in how the mineral is written and pronounced.

Uses and significance within stories vary. Lüliid is frequently valued for luminous properties and for rumored energy storage or piezoelectric effects, making it a sought-after material for jewelry, arcane devices, or power conduits in fantasy and science-fantasy settings.

Cultural reception is diverse across works. Some authors treat lüliid as sacred or protective, while others frame it as a common narrative macguffin. Encyclopedic entries describe lüliid as a narrative construct rather than an actual mineral, highlighting its role in worldbuilding and fictional geology.
