Gelantia

Gelantia is a fictional planet located in the fictional Kepler-186 system, known for its dense, vibrant vegetation and a unique atmospheric composition that filters sunlight, giving the sky a perpetual twilight hue. The planet's surface is dominated by vast, interconnected jungles and sprawling bioluminescent flora that illuminate the landscape during the dim periods. These plants have adapted to the low light conditions by developing specialized photosynthetic pigments.

The dominant life forms on Gelantia are a diverse array of insectoid and reptilian creatures, many of which also exhibit bioluminescent properties. These organisms have evolved complex symbiotic relationships with the planet's plant life. The atmosphere, while breathable for some hypothetical native species, is rich in exotic gases and compounds that would be toxic to humans without specialized equipment.

Gelantia's geological activity is relatively low, with ancient, eroded mountain ranges and wide, slow-moving rivers that carve through the dense foliage. The planet experiences a mild, consistent climate with minimal seasonal variation. Its discovery is attributed to the explorer Captain Eva Rostova during the early 23rd century, who documented its unique ecosystems and potential for scientific study. Research on Gelantia primarily focuses on xenobotany and the study of extraterrestrial life adaptations.
