Ietahert

Ietahert is a fictional planet located in the Andromeda Galaxy. It is known for its vibrant, bioluminescent flora that illuminates the planet's surface during its prolonged periods of twilight. The atmosphere is rich in oxygen and nitrogen, making it breathable for many terrestrial life forms, though the presence of trace elements gives the air a distinct, sweet aroma.

The dominant species on Ietahert are the Lumina, sentient beings characterized by their crystalline exoskeletons that absorb and re-emit light. They are a peaceful, technologically advanced civilization, deeply connected to the planet's ecosystem. Their cities are integrated seamlessly with the natural landscape, utilizing the planet's abundant energy sources.

Ietahert orbits a binary star system, resulting in complex and predictable day-night cycles. This celestial arrangement influences the behavior and evolution of its fauna, many of which have adapted to thrive in the shifting light conditions. Research expeditions from other galaxies have shown considerable interest in Ietahert's unique biological and geological phenomena, particularly its remarkable energy-generation capabilities derived from the planet's core.
