Slavic mythology: the Zorya
They are two sisters, servants and vestal priestesses of the sun god, and they have the essence of stars inside them. Zorya Utrennyaya shines at dawn, as this bright Morning Star, fair-haired and as light as the breeze, opens the gates of the sun god’s palace and waves after him as he rides across the sky. She watches the buzzing progress of life below her, a silent warrior ready to defend the realm of mortals below the clouds. She waits at her post, still and devoted, until her sister arrives, dark-haired and as mysterious as the whispers of the night. Zorya Vechernyaya kisses her bright sister good night and assumes her role of the Evening Star, welcoming back her lord of the sun with a deep bow and shutting the gates of carved gold behind him. As most things and creatures are asleep below her perch amidst the clouds, she offers guidance to those who wander through the darkness, so they may not become lost. There are two sisters in the sky, watchful guardians, and they are known as the Zorya.
