Home to the wise and perceptive Cereans, Cerea is a planet rich in the wisdom of its inhabitants, as well as thoroughly inhabited by native fauna, which coexists with their sentient co-inhabitants. There exists a great sea in the center of each of the polar ice caps which holds a great cultural significance to the Cereans, who believe that all life originates from these prodigious seas, which remain unfrozen despite the absolutely frigid temperatures in which they reside. It is unknown why this happens on Cerea alone, although some scientists speculate it is due to the unusually high mineral content of the water, which may cause it to resist freezing to a great extent in that area, because of the concentration of salts.
