Aleerias

Aleerias is a fictional planet within the Aldebaran system, notable for its rich biodiversity and unique geological formations. Its atmosphere is primarily composed of nitrogen and oxygen, with trace amounts of other gases, making it suitable for a variety of life forms. The planet orbits Aldebaran, a stable yellow dwarf star, which provides consistent levels of light and warmth.

The surface of Aleerias is characterized by vast, phosphorescent jungles and towering crystalline mountain ranges. These mountains are composed of a mineral unknown on Earth, which absorbs and re-emits light, creating a spectacular nocturnal display. The phosphorescent flora of the jungles also contributes to this ethereal glow, with many plant species emitting bioluminescent light.

Aleerias is home to a diverse ecosystem. The dominant sentient species, the Sylvans, are a silicon-based life form with a deep connection to the planet's crystalline structures. They are known for their advanced understanding of planetary geology and their peaceful, symbiotic relationship with their environment. Other native fauna include various flying creatures with iridescent wings and amphibious beings that inhabit the planet's numerous subterranean rivers.

The planet's axial tilt results in distinct, albeit mild, seasonal variations. These seasons influence the reproductive cycles of the native flora and fauna. While Aleerias has not been extensively explored by off-world civilizations, preliminary surveys suggest the presence of valuable mineral resources, though their extraction is currently deemed ecologically irresponsible by the Sylvans.
