Princess Celestia had ruled Equestria alone for well over a thousand years when her sister returned to the world.
They would overcome the differences that so separated them before even though Luna would still remain reserved towards the world at large.
And so it came to be that when the older sister, beloved by all, looked out across the kingdom her younger sister, the reserved Princess Luna, turned her Gaze inwards in search of her own answers.

Rated T due to some heavy subject matters.

The absolutely gorgeous cover was drawn by Wooxx, who I'd recommend warmly when it comes to commissions: https://wooxx.deviantart.com/
