Rastu

Rastu is a fictional planet located in the Andromeda galaxy. It is known for its unusual flora and fauna, adapted to the planet's unique atmospheric conditions. The planet's surface is primarily composed of crystalline structures that refract light in a dazzling array of colors. Rastu experiences two distinct seasons, a long period of intense solar radiation followed by a prolonged twilight phase.

The dominant intelligent species on Rastu are the Lumina. They are bioluminescent beings who communicate through complex patterns of light emission and subtle shifts in their body's phosphorescence. The Lumina have developed a society deeply intertwined with their planet's natural cycles, utilizing the crystalline structures for shelter and the planet's energy for their technology. Their understanding of light and energy is far advanced, allowing them to manipulate their environment in ways not yet understood by other galactic civilizations.

Rastu's ecosystem is characterized by plants that absorb and store light energy, releasing it in soft glows during the twilight phase. Many of the planet's creatures have evolved to harness this stored energy, either for sustenance or as a means of defense. The overall environment is serene, punctuated by the gentle hum of energy currents and the soft, shifting luminescence of the landscape and its inhabitants. Despite its beauty, Rastu remains a relatively isolated world, its inhabitants preferring a contemplative existence.
