Selerias

Selerias is a fictional planet within the Andromeda Galaxy, notable for its unique atmospheric composition and the resilient flora and fauna that inhabit its surface. The planet's atmosphere is rich in a gas colloquially known as "aetherium," which gives the sky a distinctive violet hue and contributes to the unusually low gravity experienced by its inhabitants. This low gravity has resulted in the evolution of towering, spindly plant life and creatures with elongated limbs and lightweight skeletal structures.

The surface of Selerias is characterized by vast, crystalline plains interspersed with deep, bioluminescent canyons. Water is scarce, primarily found in subterranean reservoirs, and much of the planet's ecosystem relies on the aetherium-infused moisture that condenses on plant surfaces. The dominant life forms are the Selerians, a sentient species with chitinous exoskeletons and multiple sets of appendages adapted for traversing the planet's varied terrain. They have developed a complex society based on communal living and a deep understanding of their planet's delicate environmental balance. Their technology is largely bio-integrated, utilizing the natural properties of Selerian flora and fauna for energy, construction, and communication. Explorers from other star systems have noted the planet's unusual beauty and the Selerians' peaceful but wary nature towards outsiders.
