Princess Celestia arrives at her castle's balcony. She sees her sister, Luna getting ready for the night shift. Princess Luna looks at Celestia with disgust.
"Luna, I..," Luna walks past her.
"Save it. I have to get ready to enter Spike's mind and calm him down."
"Spike isn't here."
Luna's eyes beam wide open after hearing that. She turns to Celestia. "What do you mean Spike isn't here? You let him stay, or did he killed himself along the way?"
Princess Celestia takes a deep breath. "We found him. Spike is surrounded by a magical, powerful, loving family."
"What happened?" Princess Luna takes a seat in Celestia's room. She's intrigued with the news.
"First, before anything, I want to say that I'm sorry. You were right about everyone being entitled to live life happily. I didn't see the bigger picture of the outcome until my horn and wing were cleaved off."
"How was that possible? You are the strongest Alicorn in existence," Princess Luna is perplexed.
"The world Spike resides is known as Earth Land. Magic power there is beyond anything we can ever comprehend. I've witnessed two battles of this event known as the Grand Magic Games, each wizard has a particularly skill, and it's a sight to behold. Twilight and I were called into battle against Spike and his comrade, Erza Scarlet."
"Who's Erza Scarlet?" Luna is curious to know who she is.
"An Alicorn Slayer."
Princess Luna cringes at the title. "How is that possible?"
"Our magic made us stronger but, we were nowhere at the elite levels of the magic guilds competing. Erza Scarlet dominated me with her magic power and strength. If Tirek was running wild with all the magic in Equestria, Erza would beat him in less than ten minutes. It took her a few moments to defeat me."
"Oh.., wow..," Princess Luna's jaw drops. She has never heard a creature that can do that. "What about Spike?"
"He utterly destroyed Twilight with his magic. In Earth land, he's Spike the Fairy of the Fairy Tail Guild. Spike's power scares me more than losing my life. He's insanely wicked powerful, Luna."
"Where's Twilight?" Luna asks.
"Still in Earth Land," Celestia sighs heavily.
"What happened with Twilight?"
"Twilight has succumbed to insanity. She tried to erase Spike's memories, and Spike had a counter for it. Luna, I have never seen anyone having an answer to a memory erase spell. Twilight made a fake copy when we came for her to bring her back to Equestria. Erza proposed a wager. We beat them; Spike comes back. They beat us; Spike stays."
"Wow. So, Twilight has no chance of coming back to Equestria?"
"Discord gave Spike a magic card that'll allow him to travel here and back to Earth land. I'm sure down the line they'll encounter each other. Hopefully, Spike doesn't kill Twilight, and if he does," Celestia sighs heavily. "I don't think I want to finish that statement."
"I understand. There's no reason to go any further. With Twilight succumbing to insanity, does that mean her title of Princess is revoked?"
"Yes. If Twilight somehow returns to Equestria unscathed, she will no longer be the Princess of Friendship and will no longer be worthy as an Alicorn. Discord will remove her wings."
"So, are you going to decide who'll be next in line as your student to become a Princess?"
"No. So far, my decisions had turn things astray. Luna, you'll decide who is worthy. To be next in line, to follow the path into becoming a Princess of Equestria. When you stood up to me on not going, to protect Equestria while I was going on a worthless pursuit, you chose Equestria first. I chose to listen to Twilight in the heap of the revelation. I chose to disregard Spike's happiness for Equestria. You did what was right for Spike and Equestria at the same time. You are becoming a wiser leader, Luna."
"I'm.., I'm not sure who to pick? I don't know what it's like to take a pony under my wing. How do I do that, Celestia?" Luna is unsure about picking who is worthy of becoming her protege.
"Don't select out of the best of the best but let your heart guide you. You'll know who'll be right to become a Princess someday. I'm going to trust you to do this on you're own. I wish you the best of luck for a better outcome."
Princess Celestia hugs her sister and goes to bed. Princess Luna decides to not go on her dream shift and to think about choosing a protege for the future of Equestria. Princess Luna trots to her room to figure where to visit to see potential mares that'll follow her.
"What am I supposed to do?" Princess Luna stares at the moon to come up with suggestions. "Who do I know could be worthy of taking Twilight's place as future Princess of Equestria?" Princess Luna sighs. "Maybe choosing a random location is not my best option. Follow my heart," Princess Luna views Ponyville from her window. "Maybe, I need a group that'll be the future of Equestria?" Princess Luna gets an idea. She starts jotting down possibilities of Equestria's future.
Princess Luna spends two hours jotting all sorts of possibilities for Equestria. She's starting to have fun with the project instead of worrying about who to choose.
It's now 7:30 in the morning. The moon is still up, which worries Celestia a bit. She lowers the moon and raises the sun. She wonders what her sister, Luna, is doing. Princess Celestia decides to check on her sister. When she enters her room, she sees Luna's notes on the walls with diagrams and about the possibilities of Equestria's state.
"Luna, how are you feeling?" Celestia asks her sister.
"Great!" Luna is enthusiastic.
"In a span of a night, my sister has a plan in motion. I guess she listened to her heart after all." Princess Celestia smiles.
"I'll be back, Celestia," Luna said.
"Where are you off to?"
"To see Discord, I need a second opinion," Princess Luna flies off to Discord's house.
Princess Celestia couldn't help herself and snoops through Luna's notes and diagram. She's amazed to see what's she thinking of until something strikes her. Princess Celestia doesn't see Luna's notes about one protege but having seven proteges.
