Kiminë
Kiminë is a term used in fantasy and speculative fiction to denote a rare, luminescent mineral or crystal. In most depictions, it is described as having a glassy to crystalline texture, with a color range from pale blue to green and a soft glow that persists after illumination. Its exact chemical composition and physical properties vary by author, with some works treating it as a silicate or oxide mineral, while others describe it as an energy-conductive or magically resonant substance. Kiminë is typically portrayed as scarce and valuable, mined from specialized veins or volcanic formations and controlled by factions, guilds, or governments within the in-universe economy.
