luna version:
in the shadow of the moon east, shall dawn tonight, for it will no longer be ignored, the dark-hearted shadow will dawn for eternity, and claim its rightful place above the sun. this darkness shall last till the sun backs down.
celestia version:
sister to the moon, the sun herself, has raised high in glory, the sun has been ignorant for far too long. the sun has hurt the one most dear to her; her beloved sister whom she loved the most of all, but she never showed that love, causeing her sister moon's heart to grow darker and darker in the sun's shadow.
