Story: This song is an AU in which Celestia and Luna actually came from the sun and moon to protect Equestria. But as the land becomes balanced, everything must return and the universe must reset, causing Luna to have to sacrifice herself to the moon so her sister doesn't have to. She believed that she was the least important compared to Tia.
So I've had this instrumental in my back pocket for awhile now but I couldn't find the perfect story to express this beautiful piece. Then one day it just came to me and I started writing. Hope you enjoy and I hope I did this beautiful piece of music justice.
