From the introduction:
Creedona, the original god and creator, traveled as a bolt of pure energy, blazing through the cosmos for many lifetimes. Her light shone ahead of her like a beacon in a sea of darkness. She was on a journey determined to find her lost sister, Ghyrma. Creedona’s radiance was juxtaposed by the absolute darkness pursuing her every movement. Unable to glimpse what was trailing her, Creedona never realized that Ghyrma had been following her all along. Unable to find her elusive sibling, Creedona eventually grew tired and curled herself into a ball falling into a deep slumber. As she rested her body grew and grew until she became the size of a planet, forming the world on which Revilo sprawls. Bored with waiting in the cosmos, Ghyrma broke through the atmosphere and landed on the planetary mass that Creedona had formed, becoming the first to walk the earth.
