Time fell in love with Chaos’s creation, Gi, and by and by she bore him twins —male and female. The girl shone bright as all the stars above in the Darkness, and was called Astéri. The boy was pale as the ghost of long forgotten gods, and was called Chlomós. The two grew together, inseparable from the womb. Closest to Gi, over her the two watched, jealously guarding the mother they loved so dearly.
Too soon Gi was old and her many children were scattered. Above her remained her eldest, and upon her green surface wandered a multitude of playful creations. Greatest among her creations were the humans, for they were rational and intelligent creatures. But with rational comes a certain cost. A great battle raged between the mortals who dwelt upon her bosom. Grieved then, Gi cried to the gods in remorse for fathering such monsters, for granting them her wisdom.
And Astéri feared for her mother, and turned her face from the mortals, leaving them in utter Darkness. Filled with remorse, the mortals cast aside weapons and pleaded for her to return, to once more grant them the blessing of her light. But Astéri was not moved. In her stead, Chlomós came and dwelt; but his light brought no warmth, for it was a pale, cold light. And the mortals were afraid, for Death was close at hand.
Taking pity on her creatures, Gi raised her own supplications to her daughter, begging for Astéri to return. But all for naught. Astéri did not return, and the mortals dwelt in darkness, and the shadow of Death came upon them. Despair took root in the mortal hearts, and grew into a deadly vine, cutting off all hope and belief. The people turned from prayers and worship of the gods, all except a small group.
This small group of men, women, and children remained hopeful. Every day they prayed for the sun to rise. Hearing their prayers Chlomós wept for he could not save the mortals, even the ones he loved so dearly. Crying as he had not since he was a child, Chlomós presented himself on his knees to his sister and begged for her return. Taking pity on her brother, Astéri pulled him to his feet and together, hand in hand as when they were children, the two returned.
Just as hope was fading from even the most faithful, Astéri cast her light once more over Gi, and the world was bathed in her warm glow. Thus the twins brought peace and prosperity to the mortals once more. From that time forth, they split the effort of guardianship, and Astéri called her contribution Day, and her brother’s Night, and they lived in harmony with the mortals.
