“Luna, please understand…”
The moon had long since risen, and Celestia had urged the younger sister to return to her as quickly as possible after the ceremony. Try as she might, the mare of night could not detect anypony spying on her; and from the lecture Celestia was currently giving her she guessed that Celestia didn’t know why Luna had gone down to Ponyville; only suspected.
“I ask you to leave the past be because it is dangerous to press further. The ponies spying on you live outside of our borders and are thus none of our concern.”
“But, Celestia, it’s not…”
“Luna, please. If they are found here again, they will be dealt with according to our laws.”
The younger Princess sat down and heaved a frustrated sigh. “But that’s not the point. I just want to know who they are and why they want to watch me. Nopony watches me that intently.”
Celestia smiled and shook her head. “Everypony watches you eagerly, my dear sister. Do not worry about those outside of our lands; concern yourself with the ponies who love you.”
Luna looked down wordlessly, and Celestia left her to her thoughts. The door closed quietly, and as soon as Luna was sure her sister was out of earshot, she smacked the bed with a hoof and covered her eyes with a frustrated sigh.
“I should just leave it be. Colt of the Moon, huh… Probably just a ponytale.” But the words felt false on her tongue, and she could not convince herself to believe them - try as she might.
She sighed and closed her eyes, allowing the warmth of night to spread over her. It was hard for her to relax when the night was still new; the song still hummed through her veins, so instead she would listen. Not just the voices of the stars and the moon, but an endless whispering of voices lost to the sun; those of moon-worshippers lost to memory, of ancient rulers, of the most powerful night-being of all. She sought the tales of the past, any mention of the Colt of the Moon and his red magic, but heard nothing. Theia, the Lady of the Night, was silent, and no amount of Luna’s pleading would encourage her to share her secrets.
