"Sister, I wonder if I might have a moment of your time," Luna paused, placed a barrier spell around her writing desk, then turned to Celestia. "Don't worry." Celestia chuckled. "I'm not going to insert a jest into your letters this time."
"Better to take precautions anyways." Luna replied. "What cause brings you to our den, Dear Tia?"
"It's about the posters that you designed."
Luna rubbed around her horn. "Were there too few? I was assured that 20,000,000 was more than ample to provide awareness in the majority of Equestria and the neighboring lands. Should I have budgeted for more advertising?"
Celestia snickered softly into a hoof. "No Lulu, I think you have enough coverage. I was wondering if the acronym on the poster, was intentional."
"Acronym?" Luna lit her horn and conjured a copy of the poster. "To what do you refer, Sister?"
"Well, read it off to me."
"The first ever Nocne Mesta Nightmare Night Masquerade Ball, will commence at the onset of evening, on the last day of Hecat '10." Luna then listed off the events and attractions that were planned. "I do not see how the letters are lined up on the vertical, to form a word."
"Nom nom nom."
Luna stared at her sister for a moment, before rolling up the poster. "The alliteration of 'N' and 'M'. I perceive that now. And I did hire a number of caterers to ensure that there will be an abundance of food on hoof."
"Would that I could attend," Celestia placed a fetlock to her forehead. "Alas, my presence will be needed in Neighpon for the draft of their next six-year plan."
Luna smirked. "I have often said that they should extract the timbers from under their tails, and learn how to loosen up. But I suppose their bureaucracy has a purpose if it allows them to maintain a multi-millenial empire."
"They were one of the few to not fall to Discords influence." Celestia added. "They were too orderly for him to establish a clawhold."
Luna burst into laughter. "Yes, I recall how he ranted about them after his release." She lightly swatted her sisters' flank with the rolled-up poster. "Worry not, we shall hold a place of reserve for you, in case you have a free moment."
"At any rate, I wish you the best." Celestia stated, extending a wing over Lunas' back. "Have you acquired a costume yet?"
"Fret not, Celly," Luna replied. "I shall be properly attired for the event. And not as the Bringer of Night Eternal."
"May I see it?" Celestia asked.
Luna blushed. "Tis still at the shop, but it is reserved." Celestia nodded and left. Luna waited a moment, then headed out as well. After a couple of inquiries with the castle staff, she located Lime Sherbert in the southern hall of the third floor..
"Oh, your highness." Lime looked over after finishing her task. "I noticed your telescope was looking a little dusty, so I gave it a once-over with some polish. Did I accidentally push it out of alignment?"
Luna blinked. "No, that is not why I sought you out," She lowered her head to touch noses with the unicorn. "I ask your assistance in browsing the shops, for Nightmare Night attire."
Lime tapped her cheek in thought. "I know that we often get pre-made articles for your outings as Cynthia. perhaps she would look good as-"
"Nay, Tis I as myself who shall be in costume." The alicorn made a gesture. "My stature and wings must be taken into account this time."
"In that case, I know of a few places that might interest you." She began leading the way.
"And Lime." Lime swiveled her ears back to listen. "If the telescope has been pushed out of alignment, you will be rebeading mine abacus." They shared a laugh.
