Seltar

Seltar is a fictional plant originating from the world of Xylos, as depicted in various science fiction narratives. It is characterized by its bioluminescent properties, emitting a soft, ethereal glow, particularly during the twilight hours on Xylos. The plant typically grows in damp, shaded environments, often found clinging to the sides of ancient rock formations or near slow-moving water sources. Its leaves are broad and somewhat leathery, possessing a deep emerald hue that contrasts sharply with the pulsating light it produces.

The light emitted by seltar is believed to be a result of symbiotic microorganisms living within the plant's tissues, a common adaptation in the low-light conditions of Xylos. Seltar is not known to be a food source for most native fauna, though some insectoid species are attracted to its luminescence. In some fictional accounts, the plant's sap has been explored for its medicinal or even recreational properties, although such uses are often speculative within the fictional context. The ecological role of seltar is primarily as a producer of light, contributing to the unique ambiance of its native environment. Its discovery and study are often a point of interest for xenobotanists exploring the diverse flora of Xylos.
