Elandria

Elandria is a fictional planet within the Andromeda Galaxy, notable for its unique atmospheric composition and the bioluminescent flora that characterizes its surface. The planet orbits a K-type main-sequence star, providing a stable, albeit dimmer, light source compared to Earth's sun. Elandria's atmosphere is rich in nitrogen and argon, with trace amounts of oxygen and a significant presence of an unknown noble gas that contributes to its characteristic auroral displays.

The dominant life forms on Elandria are plant-based. These organisms have evolved to absorb energy from the planet's geothermal vents and the faint starlight, resulting in a constant, soft glow that illuminates the landscape during the planet's long nights. These bioluminescent plants range from towering, tree-like structures to low-lying, moss-like ground cover. Animal life is scarce and largely subterranean, adapted to the dim surface conditions.

Elandria's terrain is varied, featuring vast, silicate deserts, expansive shallow oceans filled with nutrient-rich water, and mountain ranges sculpted by ancient tectonic activity. The planet experiences moderate seismic activity and infrequent, but powerful, atmospheric storms. Scientific interest in Elandria stems from its potential to harbor unique biochemical processes and the possibility of understanding life adaptation in low-light environments. Exploration has been limited due to the planet's distance and the challenges posed by its atmospheric pressure and temperature fluctuations.
