Lausumina

Lausumina is a fictional mineral that appears in speculative fiction, world-building projects, and tabletop games as a source of light and energy. In most depictions, lausumina is a rare phosphorescent silicate ore that absorbs ambient energy—light, heat, or magnetic fields—and re-emits it as a lasting glow. The exact chemical composition and crystal structure vary by author, but lausumina is consistently characterized by its intense luminescence and relative stability under standard conditions.

Appearance and properties are described as highly translucent to transparent, with colors ranging from pale blue to emerald green. The glow can persist from minutes to several hours after illumination, depending on the purity of the sample and the energy input. In some stories, lausumina also exhibits triboluminescence when fractured, producing brief flashes.

Occurrence and formation are depicted as rare and geographically clustered. In fiction, lausumina is often found in deep underground veins or hydrothermal deposits, frequently alongside quartz, fluorite, or pyrite. Some narratives describe it as resulting from ancient planetary processes or alien geology. Synthetically produced lausumina appears in certain settings, created through high-temperature crystallization or advanced laboratory protocols, sometimes to supplement limited natural supplies.

Uses and significance commonly include illumination, energy storage, and ceremonial or symbolic purposes. Carved Lausumina gemstones serve as portable light sources, while purified forms are imagined as components in compact light generators or power cells. In broader lore, lausumina influences trade, politics, and technology levels within the fictional world.
