Earth was the name of Parthenon's brother. Earth was a warrior who withstood the harshest of battles, sacrificing himself for the other gods against Rao, the god of Fire. Legend has it that when Rao turned on the other gods and began to hunt down the gods, Earth was the one who kept Rao at the gates of Ceres, preventing Rao from destroying Greenland. However, since Rao was defeated, the mortal world plunged into an ice age (Around the time this legend was written, there was an ice age on Ganymede).
