Eksian
Eksian is a fictional planet within the Andromeda Galaxy, notable for its unique atmospheric composition and the enigmatic ruins found scattered across its surface. The planet orbits a binary star system, leading to extreme diurnal temperature fluctuations and a complex orbital pattern that influences its seasons. Eksian's atmosphere is primarily composed of methane and ammonia, making it inhospitable to most known life forms without specialized environmental suits. Its surface is characterized by vast, arid plains, deep canyons carved by ancient, now-dry rivers, and towering crystalline formations that refract the light of its twin suns.
Archaeological evidence suggests a highly advanced, long-vanished civilization once inhabited Eksian. The most prominent remains are
