Needtu

Needtu is a fictional planet located in the Andromeda galaxy. Its surface is characterized by vast, crystalline deserts interspersed with deep, phosphorescent oceans. The atmosphere is a thick, nitrogen-rich blend with trace amounts of helium and argon, giving the sky a perpetual twilight hue.

The dominant life form on Needtu is the Lumina, a sentient species that has evolved to thrive in the planet's low-light conditions. Lumina are bioluminescent, emitting a soft, internal glow that varies in color and intensity depending on their mood and environment. They possess a unique form of communication that utilizes complex patterns of light pulses and subtle sonic vibrations.

Needtu's geology is rich in silicate crystals and rare minerals, which the Lumina utilize for their technology and architecture. Their cities are sculpted directly from massive crystal formations, glowing with an inner light that mirrors the Lumina themselves. These structures are designed to harness geothermal energy and the planet's ambient light.

The Lumina society is highly communal and focused on maintaining ecological balance. They have a deep understanding of their planet's intricate ecosystems and have developed sustainable practices to ensure their survival without depleting resources. Their culture emphasizes harmony, knowledge sharing, and a profound connection to their luminous environment.
