Sky stood just outside of the throne room doors in Canterlot Castle. He was quite ready for dinner, but according to Luna's schedule, the induction was first, then the guests and gathered members of Luna's court would proceed to the main dining hall for what was sure to be an amazing meal.

As he hadn't had anything to eat since getting up, his stomach was positively rumbling, and he was hoping whatever was about to happen in the throne room was quick. Not only because of his hunger, but now he wasn't entirely positive if his onesie's enchantment was working, and if not, how conspicuous was his diaper underneath the black cloak and formal satin vest he now wore.

The pegasus heard Luna's muffled words on the other side of the door as she continued to give what was now beyond a five minute speech, something about the welcoming the newest member of her night court. As he took another deep breath, he convinced himself to pay attention to just Luna on his walk up the carpet. He also began to wonder if those in attendance would be applauding on his walk up to the throne. If not, would they hear the crinkle of the diaper underneath his clothes?

"And now, mares and gentlecolts of the Night Court, I proudly present to you, our newest member, Mister Sky Scribbles," he heard Luna say through the doors, moments before the edges glowed blue with her magic, and they opened.

This was it.

Keeping his eyes glued to the throne, he stepped through the doorway and began to walk down the center of the expansive room towards the throne at a steady gait, doing his best to not look like he was trying to ignore the three dozen or so ponies who had gathered for his official induction.

The walk was over before he knew it, and he came to a stop at the bottom of the steps, with Luna looking down at him with a warm smile.

"Sky Scribbles, while this short ceremony would conclude with you taking an oath of office, as you know, your station is rather extraordinary, and thus your oath should be as well. Sky Scribbles, do you solemnly swear to stand vigilant where few have tread, against threats few can comprehend, and render aid to those who have lost their peace in the realm of dreams?" Luna asked.

"I do, Princess," Sky replied, the softest of smiles on his face, before giving a formal bow. Luna descended the steps, lit up her horn, and lowered her head, the side of her glowing horn softly coming into contact with the sides of his barrel, before standing up right again.

"Rise, Sir Sky Scribbles, Guardian of the Night," Luna said, now returning the smile.

"Mares and gentlecolts of the Night Court, invited guests, may I present Sky Scribbles, the first Night Guardian of this era."

Sky turned to face the crowd as the applause finally started. He saw uniformed guards, Princess Celestia, who had evidently cleared her evening to be here, and even caught a glimpse of Lyra and Bon Bon, whom Luna had told him she had taken the liberty of inviting.

"Now let's not let the inviting aromas of the dinner that awaits us tempt us any longer. Please make your way to the dining hall," Luna instructed the crowd.

As the ponies in attendance turned to exit the dining room, Sky turned to Luna, knowing he wasn't on ceremony at the moment.

"Luna, are you certain the enchantment on my onesie is working? When I went to see Trim Lace to get the rest of my outfit for tonight, she most certainly noticed what was under all this," Sky asked her in a whisper, not wanting to say so much when half the room's occupants were still slowly filing out into the corridor towards the dining hall.

"Ah, Luminescence must have informed you about the incognitus enchantment. Fear not, Sky, it is still working, but perhaps not in the way that you thought it did," Luna explained, leaning in closer to whisper in his ear. "It doesn't hide your diaper. To everypony else, it makes it as normal to their eyes and ears as the rest of the uniform. That side of yourself is a considerable source of your strength in the dream realm, so it is, in essence, a completely normal part of your attire now."

Sky gulped nervously as his days at the castle now replayed in his mind. Every walk he took down the corridors, every time he had cooked with Celestia in the kitchen... Each and every pony he had interacted with here now knew he was diapered. He was having trouble wrapping his mind around the possibility that all of them thought of it as completely normal.

"So, are you ready for dinner? Lyra and Bon Bon are quite anxious to catch up with you," Luna told him.

Sky smiled at his princess, and nodded.

"Quite ready, princess," he replied, his stomach grumbling again.

The two of them waited for the last of the crowd to file out of the throne room, then made their way to the dining hall as well, staying behind the crowds, hoping everypony would be seated by the time they arrived.

Towards the center of the room, there was a table for four with three ponies at it, and Sky immediately recognized the three sitting there; Bon Bon, Lyra, and his younger sister, Windy, a light purple pegasus with a flowing blonde mane and tail.

"Nopony told me you guys were coming," Sky said with a smile.

"Well, I'm sure the princesses can't keep too many surprises, so they take advantage when they can," Windy replied with a smirk.

"Are you joining us, Princess?" Sky asked, turning to Luna as the chair was pulled out for him.

"Nonsense, Sky. My sister and I are hardly going to allow any hobnobbing at your table. This is your evening, after all. I'll see you later tonight for your first official night on duty. Enjoy your meal and company," Luna told him, before heading off to a table farther away.

Just as he sat down, Princess Celestia came up to his place at the table.

"Congratulations, Sky. I'm quite happy that you'll be staying here with us. I'm very much looking forward to having you as a cooking partner," Celestia told him, coming in for a hug, before going farther down the dining room to join her sister at one of the other tables.

"Well, looks like you've come a long way, bro," Windy said, picking up her glass of wine. "I know these last couple years haven't been the easiest to deal with, and it seems you're finally landing on your feet. To Sky!"

Lyra and Bon Bon immediately raised their glasses, before Sky hesitantly raised his as well.

"To all of you," he said. "You were all there for me these last couple years. This will likely be my only glass of wine this evening; I do have work tonight as Princess Luna said, so I'll use it as a toast to all of you. Any time you want to come visit me here, I would be honored to have you. It's the least I can do for everything you've done for me."

Sky raised up his glass and looked at his three dining companions.

"To family and friends."

Author's Note

I'm not 100% sure where I want to end this story. I've received a couple of requests in the past to perhaps show the kinky hi jinks Luna and Sky get up to in their spare time.

I'll give it some thought. In the meantime, thanks for reading!
