Luna stood on the balcony connected to her room at Canterlot Castle, looking over the city with her sharp eyes.
“It isn’t easy to watch after you’ve been the one implementing everything,” a smooth low grit sandpaper like voice drifted into her ears from behind her.
Luna glanced behind to see the bipedal in exquisite attire, carrying a very unusual and massive sword, crimson boiled on the black sharpened edges and pale white flat of it, evaporating quickly on the inscriptions.
“You have come to kill us?” Luna noted the purple coloring to her bedroom door past the balcony arch. She knew he was keeping it shut no doubt.
“No, I don’t...kill much anymore,” he hefted the huge, slight curve-ended, partially serrated blade. The nine foot long weapon held a crescent moon attached to only one side of it. The weapon flitted away in purple and black flames, disappearing, “though I miss battle sometimes, I relish any duel I’ve been invited to. It gets lonely without any worthy challenger.”
“All of those sentiments we share with you,” Luna looked back over to the city while he walked over, “what should we call you?”
“Lucius is fine enough,” he placed his hands on the railing. He knew it was a safe enough moment to meet with her without stopping the entirety of Equestria, “I’m sorry for your loss, Luna. Your sister did love you dearly.”
“We know,” she let a long moment of silence pass as the wind passed over them, “we doubt you came here just to share sentiment and friendly conversation. What is it you want from us?”
“Very direct of you. Well,” the same translucent black orb filled a now open hand that he held in front of them, “I came to make you the same offer I once offered Celestia,” the sphere filled with swirling purple trails that contrasted the blue sky.
“And what is it my sister declined?”
“Very astute of you, Luna. I suppose you have also felt the tinge of mortality beckoning at you,” Lucius looked to his left, “so I offer you a peaceful paradise. Your happily ever after. I know command of Equestria has been transferred to Twilight,” the orb shrunk, “you’re deciding for yourself alone.”
Luna pondered in a quiet moment, looking at the orb that very much felt like a home. She knew Lucius was offering her something after this, but she didn’t know what. His gentleness and genuine words were enough to determine that it wasn’t something negative.
“Is there anypony we know there?” Luna asked, meeting Lucius deep eyes with her own sharp pupils.
Lucius smiled, “no, you would be the first of your kind there. I have countless subjects who all live peacefully and without conflict. I’m sure one of your kind would follow you there later on.”
Luna stared back at the orb and he opened his mouth again, “I would keep you company myself and we could even come back and visit Equestria again should you like,” she smiled at Lucius’ words.
Luna was a proud pony, Luna was a fit pony, Luna was a fierce pony. Though she still stood strongly, she did long admit to herself that she was getting weaker at an alarming rate. It wouldn’t be long before she departed herself.
“I accept. I think I would love to visit Equestria and see what will become of it.”
Lucius moved the orb in front of her, “take it and house this within yourself. Though your form will change, you will still be true to yourself and betrothed only to yourself.”
Luna took the orb and the black shell peeled open. The small strands of purple threaded their way around her hoof before seeping into her skin naturally.
“This is a profane power.”
“Luna, it is all about application. Origin never did matter,” Lucius smiled wider, lowering his hand, “I do think I have a few more challengers at home waiting for me. Those who have crossed the Not of their own ambition to unseat me. I’ll be seeing you at my castle door, friend,” he walked back into the room and ripped a portal open, vanishing along with it while the door of Luna’s room slowly creaked open.
“Princess Luna?”
“Oh, Twilight, mysterious things happen in the weaving of our tapestries. Would you agree?”
