Aleron, a planet choked by smog, resided within the Freeworlds Territory of the Tapani sector. This world featured both domed cities nestled in canyons and subterranean urban centers. The planet's crust and mantle contained significant deposits of prized minerals and ores. First found during the Twelve Kingdoms Era of the Tapani Empire, Aleron was settled by Humans originating from Gilliana. The planet served as the central hub for the Aleron Trade Cooperative, Macander Heavy Ores, and the LIN Corporation. Due to the presence of these three powerful corporations, Aleron possessed a voting seat within the League of Tapani Freeworlds.
