Arveldai

Arveldai is a fictional planet located in the Andromeda Galaxy. It is known for its unique geological formations and a singular, sentient species that inhabits its surface. The planet’s atmosphere is rich in nitrogen and a trace gas that gives the sky a perpetual violet hue. Arveldai experiences two distinct seasons, a prolonged period of intense solar radiation followed by a longer, colder phase.

The dominant species on Arveldai, referred to as the Lumina, are silicon-based lifeforms. They possess bioluminescent qualities, which they use for communication and navigation in the planet's dim light conditions. The Lumina are known for their communal society, with individuals sharing a collective consciousness that allows for rapid information exchange and problem-solving. Their technological advancements are primarily biological, focusing on manipulating their environment through engineered organisms rather than conventional machinery.

Arveldai's surface is characterized by vast crystalline plains and deep, geothermal caverns. The planet's core is highly active, resulting in frequent seismic activity and the presence of exotic mineral deposits. The Lumina have adapted to these conditions, building their settlements within the more stable cavern systems. Their existence is deeply intertwined with the planet's unique energy cycles.
