Before her banishment to the moon, Princess Luna had been so lonely. The Equestian ponies adored her older sister, while she felt unnoticed by them until a little unicorn from the kitchens lets her know that her night is of value to somepony. It isn't enough though, and she turned from Harmony in an effort to hold onto her new found emotions. One thousand years pass and the little pony who had reached out to her is long since dead, leaving her feeling empty when she is alone. But the Royal library seems to have a new librarian, and she has an uncanny resemblance to her dearly departed friend.
