Sisters

"Once did a pony who shone like the sun look out on her kingdom and sigh... She smiled and said 'Surely there's nopony so lovely and so well beloved as I...'
Once was a pony whose moon shone so bright, the stars were in awe at its glow... She smiled and said 'Surely there's nopony who'd dare be asleep trough this marvelous show...'"
(Lullaby for a princess)
