Katlarn

Katlarn is a fictional plant species that appears in the "Aethelgard Saga" series of novels by author Elara Vance. It is depicted as a bioluminescent flora native to the shadowed forests of the realm of Eldoria. The plant is characterized by its soft, glowing leaves, which emit a gentle blue light, and its fibrous, dark stems. Katlarn is often found growing in damp, cool environments, typically near underground water sources or in areas with persistent twilight.

In the narrative, katlarn serves several purposes. It is a primary source of illumination in the darker regions of Eldoria, allowing characters to navigate through otherwise impassable forests and caverns. Its glow is also said to have a calming effect on certain creatures, making it a useful tool for survival. Furthermore, the leaves of the katlarn are noted for their medicinal properties, with local healers brewing teas and poultices from them to treat ailments such as insomnia and minor wounds. The plant's rarity and unique properties make it a valuable commodity, sometimes sought after by adventurers and merchants alike. The lore surrounding katlarn also suggests it has a symbiotic relationship with certain nocturnal insects, which are attracted to its light and in turn aid in its pollination.
