Raisan

Raisan is a fictional planet located in the fictional Andromeda sector of the galaxy. It is a terrestrial world with a nitrogen-oxygen atmosphere, similar to Earth's, though with higher concentrations of trace gases that give its sky a unique violet hue. The planet's surface is characterized by vast, rolling plains interspersed with dense, bioluminescent forests and shallow, saline oceans.

The dominant intelligent species on Raisan are the Lumina. They are a silicon-based lifeform, with crystalline exoskeletons that refract light, causing them to appear to shimmer. Lumina society is organized into nomadic tribes that follow seasonal migrations across the plains, herding large, docile herbivores known as 'Glimmerbeasts'. Their technology is primarily organic and bio-engineered, focusing on sustainable energy sources derived from the planet's unique flora and fauna.

Raisan's history is marked by long periods of peaceful coexistence and occasional, localized conflicts between tribes over resource-rich territories. The Lumina have a deep spiritual connection to their planet, believing the bioluminescent forests to be sacred and the source of all life. They have no known interstellar travel capabilities and have had minimal contact with other galactic civilizations, preferring to maintain their isolation. Their culture is rich in oral traditions, intricate music played on resonant crystals, and a unique form of light-based art.
