Aeru

Aeru is a fictional celestial body within the "Starfall Chronicles" universe. It is a gas giant planet notable for its distinctive atmospheric composition, which causes it to emit a soft, bioluminescent glow visible from neighboring star systems. This luminescence is a result of unique microbial lifeforms suspended in its upper atmosphere, metabolizing airborne particles.

The planet is orbited by a complex system of moons, the largest of which, called Lumina, is believed to harbor more advanced, though still non-sentient, life. Aeru's extreme gravity and turbulent atmosphere make direct exploration by conventional spacecraft extremely hazardous. Scientific probes have been deployed to study its atmospheric phenomena and potential for exotic energy sources.

Aeru's glow has made it a navigational landmark for interstellar travelers for millennia, and it features prominently in the folklore and mythology of several species within the "Starfall Chronicles" narrative. While not habitable by most known lifeforms, its unique environment continues to be a subject of scientific and speculative interest within the fictional context.
