As she prepares to lift the sun to its apex, to usher in the solstice and bring the Summer Sun Celebration to its climax once more, Princess Celestia embraces the vision of the Equestrian summer that it places before her.

In the vision the summer she is birthing plays out around her, and as a happy phantom she walks through the summer stories of the lives of Twilight, Spike, the other bearers of the Elements of Harmony, their families and loved ones, and even her own sister, Luna. As she does so, she thinks on this world, her role in it...and the gift she's given it.
