It had been a long day for the Princess Ponies in their castle. Princess Sparkle moved about one of the upper parapets, cleaning supplies floating behind her in the old stone room. Feather dusters cleaned up cobwebs while mops glided along the stone floor, occasionally floating over to a bucket and dipping into the water. The Unicorn walked around and looked out of the arch-shaped window, seeing Celestia's day coming to a close and the stars of Luna's night beginning to shine through. "It's been so long since we've seen our daughters," she thought out loud.
She turned away as several multicolored balls of fur bounded in, some of them wearing oversized armored helmets on their heads, the visors clattering. "Message from Princess Celestia!" one of the Bushwoolies said, holding up fur-covered hands and waving to the door. Several of the others ran up to Sparkle, herding her to the door.
"Gotta hear the message!"
"Gonna be important! Gotta be important! Waiting for you, Princess Sparkle!"
