Botanical Analysis
The primary source of light in the caverns is a pervasive moss species, tentatively named Lumina Aethelgardis. Unlike Earth plants that rely on photosynthesis from sunlight, this flora utilizes a complex chemiluminescent reaction between atmospheric sulfur and moisture from the thermal vents.
Symbiosis
The moss forms a symbiotic relationship with the cave's mineral deposits. The roots secrete a mild acid that slowly dissolves the rock, extracting rare earth minerals which amplify the intensity of the light emitted by the plant's cells. In return, the light attracts small, flying subterranean insects that aid in spore dispersion.
