kezébl

Kezébl is a fictional mineral introduced in speculative geoscience and fantasy literature to describe a crystalline compound with unique luminescent properties. The term is derived from a synthesis of roots in the fictional languages of Xyrath and Teresian, where it roughly connotes “bright stone.” In-universe, kezébl forms in high-temperature hydrothermal systems within continental rift zones, typically presenting a prismatic habit and a glassy, iridescent surface. It has a Mohs hardness around 6 to 6.5 and a low thermal conductivity, but shows a pronounced afterglow when exposed to light, emitting a pale blue-green light for several hours. Its electronic structure includes a band gap near 1.8 eV, making it a candidate for photonic and optoelectronic applications within the setting’s technology.

The mineral’s discovery is attributed to a 5th-century explorer in the fictional region of Athera. In modern fiction, kezébl is mined in regulated pockets to balance ecological concerns; major production centers appear in the Corallen Basin and the Siryth Highlands. It is commonly alloyed or combined with other minerals to create light-emitting composites used in signage, jewelry, and ceremonial objects. Trade for kezébl is governed by regional mineral laws and often overseen by craft guilds that monitor ethical sourcing and fair distribution.

Culturally, kezébl symbolizes knowledge and illumination. Placed on altars or worn by scholars, it is said to enhance memory and focus in mythic narratives. The term has appeared in fictional encyclopedias and worldbuilding compendiums as a case study in mineral ethics and storytelling.
