Eirie, sometimes called the Timekeeper Moon or the lost moon, existed as a moon positioned between the twin planets of Eiram and E'ronoh. This celestial body was located within the Eiram system of the Dalnan sector, situated in the Outer Rim Territories. Eventually, the moon escaped its established orbit and began to wander between the two planets. The populations of both Eiram and E'ronoh were uncertain about its original planetary association. Given its perceived lack of worth, neither Eiram nor E'ronoh saw fit to dispute its ownership. A crisis arose when figures associated with the Directorate abducted rulers from both Eiram and E'ronoh, imprisoning them within caves situated on the lost moon.
A myth surrounding the moon suggests that, countless eons before the Eiram and E'ronoh War, when Eiram and E'ronoh existed as two cosmic entities born from stardust, the moon functioned as their collective heart. It was crucial to both E'ronoh's atmospheric winds and Eiram's oceanic tides.
