The Summer Solstice approaches and Equestria prepares for the welcome break, but in Canterlot Celestia plans in secret for the return of Nightmare Moon. Her duty is clear: take the five known Elements of Harmony and cast her own sister from the world forever. So what if her heart shatters into a million pieces? A fair price for the safety of all.
Yet as the hour approaches, Celestia’s resolve weakens as she is haunted by memories of happier times. She starts to entertain an insane, maybe treasonous, plan, but a plan that might just return her sister to her.
But no plan, however well thought out, ever survives execution and as matters spiral out of control strengths sequestered deep within others will surprise even the celestial princess herself. As you well know, this story has a happy ending but it is the journey that matters.
Many thanks to GhostOfHeraclitus and Bradel for prereading above and beyond the call of duty. Seriously it would not exist without their patience.
