Arenien

Arenien is a fictional planet located in the fictional star system of Aerion, within the Andromeda Galaxy. First introduced in the speculative fiction novel "Chronicles of Aerion" by author Elara Vance, Arenien is depicted as a terrestrial world with a diverse biosphere. Its atmosphere is primarily composed of nitrogen and oxygen, with trace amounts of other gases, making it breathable for carbon-based lifeforms.

The planet's surface is characterized by vast oceans, large continental landmasses, and a varied climate. Regions range from temperate zones with lush forests and fertile plains to arid deserts and icy polar caps. Arenien is known for its unique flora and fauna, many of which are adapted to specific environmental conditions. Common depictions include bioluminescent plants in its dense jungles and creatures with advanced sensory organs suited for its varied landscapes.

Geologically, Arenien possesses a molten core that generates a significant magnetic field, shielding the planet from harmful stellar radiation. Its geological activity includes volcanic eruptions and tectonic shifts, contributing to the planet's dynamic landscape and mineral resources. The planet is orbited by two moons, Aerin and Orien, which influence its tidal patterns and nocturnal illumination. In the narrative, Arenien serves as a pivotal location, often the setting for significant plot developments and the home of various sentient species, though the specifics of these inhabitants vary across different interpretations.
