Alb'arel
There are two moons visible in the night skies of Auberean. Alb'arel is the light colored moon. Rez'arel is the reddish colored moon.
As indicated by the perfect geometry of the lights on the dark side, and the symmetrical shape of one of its craters, a possible colony of extraterrestrial spacefaring civilizations may have settled there. Other than that, the origins & explanations of those lights and symmetries are unknown.
