Sourcebook
Intro
《Nine Stars》
In the deep night, at the highest point in the world, live nine sisters.
They are the Guardians of the Stars, managing the stars that float in the night sky.
Every night, they correct the positions of the stars, revive fading starlight, and return fallen stars back to the heavens.
The nine sisters possess different personalities and abilities, but they have cared for the stars together for a long time.
Someone polishes the starlight, someone organizes the constellations, and someone blooms new stars in the night sky.
No human knows of their existence.
Nor do they know that the nine sisters quietly look down upon the world every night, managing the stars.
Tonight, too, while humans sleep, the nine sisters begin their starlight management.
