Princess Celestia conceals it well, in appearance and poise, but she is an old mare. A thousand years is a long time to dwell, and her's have been filled with laughter and tears, love and loss, achievement and regret.
With a fresh open book and quill, Twilight Sparkle endeavors to capture in some semblance the journey that Celestia, Queen of Equestria and Warden of the Sun, has trekked in her centuries.
But before Nightmare Moon, before Discord, and before the Crown; in the age when Equestria was little more than a patchwork of jealous princes vying for supremacy, there was a white pony.
Tall, strong, and mysterious, she'd creep from the wilds and realize a destiny forged in elder days. A terrible evil stirs after millennia of dormancy. Equestria needs a hero, and the Wanderer of the North will answer the call.
An epic work retelling the life of Celestia, expanding on the mythology created in De Surgente Cadenteque Alicornuum, but it's not necessary to have read it beforehand.
