Elallia

Elallia is a fictional planet located in the Andromeda Galaxy. It is known for its unique biosphere, characterized by flora that emits bioluminescent light and fauna that have adapted to low-gravity environments. The planet's atmosphere is rich in nitrogen and oxygen, with trace amounts of an unknown gas that contributes to the planet's vibrant, multi-hued skies.

The surface of Elallia is dominated by vast, shallow oceans and archipelagos of floating islands. These islands, composed of a porous, buoyant rock, are home to a diverse range of plant and animal life. The dominant sentient species, the Lumina, are a silicon-based lifeform with a crystalline structure that allows them to absorb and re-emit light. They communicate through intricate patterns of bioluminescence and subtle shifts in their crystalline forms.

Elallia's ecosystem is highly interconnected. The bioluminescent plants provide energy for many of the planet's herbivores, which in turn are prey for the aerial predators that navigate the low-gravity atmosphere with ease. The Lumina have developed a symbiotic relationship with the planet's flora, cultivating specific plants for light, sustenance, and building materials. Their society is largely communal, focused on understanding and preserving the delicate balance of their world. Exploration by off-world species is limited, primarily due to Elallia's remote location and the Lumina's cautious approach to external contact.
