Canterlot, eight years since the events in Tartaurus.
The Princess of the Sun startled at the sight. “Luna? Your charioteers...?”
“Yes my sister.” The Princess of the Moon looked proudly at her guards. “It took some time, but I was able to find these two traditional Night Guard enchanted harnesses. It is disheartening to mind that their scarcity is due to mine own actions a thousand years past. Perhaps this night will be the first step upon the path to restore their rightful place in the Guard.”
The young stallions in question stood in the courtyard of Canterlot Castle. Darkly glimmering armour, slit eyes, fangs, and leathery wings making them remarkable, standing out from the normal pegasi of the Guard. Another guard, this one a mare with similar wings and eyes pulled the harness straps tight, strapping the pair into the ceremonial Moon Chariot. With a grin she stepped back. “Alright you two. You’re representing all of us. Don’t do anything I would do, you hear me?”
The matched pair stood even straighter, snapping salutes: “Yes, Sergeant.” A moment passed before one parsed out what Lethe had said. “Wait... what was that?”
The other interjected, “Yeah, you’re not a Sergeant.” The first charioteer facehooved.
Lethe rolled her eyes and stepped back with a low bow to allow the Princesses to pass.
Celestia shook her head. “Armour? Luna, you do realize...”
“As an aside,” interrupted an oblivious Luna as she almost danced across the courtyard in excitement. “It appears that there are now more Day Guards than enchanted harnesses for their use as well. As I recover my strength, I will be pleased to correct this. Although I think we can do without the cosmetic uniformity enchantments, as our Guards should not be judged purely on colour...” she looked sidelong at Celestia. “Or shape. Am I not right, Sister?”
Celestia paused for a moment, before smiling. The wounds were not fresh by any standard, but it appeared that her sister would not simply ignore them, but actively work to heal them. “You’re very likely right, Luna. Thank you for your thoughtfulness.”
The charioteers in question stole a look at each other, as Luna boarded the chariot. It had been a very, very long time, but they will serve their mistress once again, and everypony will see them do so. Celestia watched after them, long after they were airborne and gone. She turned to start the preparations for lowering the sun. It would soon be Nightmare Night for real, the first since Luna’s return from exile. With Twilight and her friends at the same celebration, it was assured to be an... interesting event.
Let the healing begin.
