Avaralla

Avaralla is a fictional plant species that appears in the "Avaralla Chronicles" series of novels by author Elara Vance. Within the narrative, avaralla is described as a luminescent flora native to the subterranean caverns of the planet Xylos. Its primary distinguishing feature is its ability to emit a soft, blue-green light, which serves as a natural illumination source in the otherwise dark environment.

The plant is characterized by its broad, waxy leaves and delicate, bell-shaped flowers that are the source of its luminescence. Avaralla is said to thrive in damp, nutrient-poor soil and is often found growing in clusters near underground water sources. In the lore, avaralla plays a significant role in the survival of the Xylosian inhabitants, providing light for their settlements and serving as a potential food source or medicinal ingredient. Certain passages suggest the plant's light can also have mild hypnotic or calming effects on creatures exposed to it for extended periods. The exact biological mechanisms behind its bioluminescence are not detailed within the fictional context.
