Phoibe

Phoibe was the second moon which, during the First age and first recorded time, once circled the moon. It was closer to the planet and was said to help regulate the planet's temperature by ensuring the encroaching deserts did not invade any farther north than it had. It also supposedly kept the northern glaciers from overcoming the Magocracy- magic or no, nature itself could not be trifled with.

Destruction
During the Cataclysm, Phoibe was pulled directly out of orbit and was intended to crash into the planet's surface. Although small for a moon, a direct collision with the planet made by it would've wiped out not only the indigenous nation in its path, but most likely most life on the continent, and that side of the planet, as well. Instead, it exploded in mid orbit, just far enough in to tumble onto the planet's surface in pieces, and yet close enough to obliterate an entire section of the continent and leave an enormous dent, which quickly filled with water. Thus, it was partially responsible for the greatest unintentional act of man-made water featuring. The body of water where it had exploded is now known as Phoibe's Sea, among other names, and sometimes sailors and denizens scavenge moon rock from its depths, thinking it to bring good luck or fortune.

Cultural Significance
Because of Phoibe's small size in comparision to it's "older" sister, Luna, Phoibe was seen as a lesser goddess of night, if not a more precious one. Citizens of Theodaria and some outlying villages occasionally held naming ceremonies on nights when Phoibe was full (less often than Luna by far, due to its slower orbit) and if the child was a girl, the families of the named would often be pressured into raising the girl as a singer or lyre player. Newborn children and occasionally new immigrants to the capital city were ritually doused in the Elpis river, preferably where the moon reflected itself, as a form of purification before being officially recognized as citizens.
