It was with great curiosity that Celestia entered Phoenix's Roost. She marveled at what Twilight's and Rainbow's children have done with the forest and her old castle. The Everfree was safer for her ponies from around the castle to Ponyville. A pair of thestrals flew by the nearby window and that brought a smile to her face. Before her change Rainbow always called Twilight's desire to have her hive be Equestrian as Heart's Warming Take 2. That title ended up being prophetic. Between the changeling hybrids of Twilight and Rainbow, the thestral refugee's from the Moonlight Empire and the trees found by Twilight's hive, and then the unique Tea'la tribe we literally did have a second Heart's Warming. As much as it hurt Twilight for that Celestia was still proud of her former student. She brought great knowledge and a past that even she didn't know about. However she was here today because Luna told she should come and one of Twilight's children has directed her to a room in her old castle. It once served as a room for VIPs so she wondered what is was being used for now and why she was being directed to it. As she closed in she heard mumbling and the sound of a chalkboard being used. She saw the door of the room she was directed to open so she peaked in to see what had Luna wearing that mischievous she used to have when they were younger.
What she saw had shocked her to her core. There glancing between a book and a formula written on the chalkboard was Twilight Sparkle. Not Twilight Sparkle the changeling queen that Celestia has seen the passed few years or Twilight Sparkle the unicorn that Celestia had known for years, whose final images will haunt Celestia for as long as she lives. Instead the Twilight Sparkle in front of her had wings, alicorn wings. And a tiara on her head. Not the design she had to reformed the Element of Magic tiara she had planned but something completely new. She couldn't be silent any longer.
“T-twilight?” The mare stop with her ears scanning before she looked behind her. Eyes Celestia hasn't seen in years look at her and brighten before a smile followed.
“Princess Celestia!” The smaller alicorn rushed to Celestia and gave her a hug. The two just spent a minute hugging like that before Celestia just had to say something.
“But how, unless this is some prank Rainbow decided to pull?” Twilight gave her a sad smile.
“It's not that kind of prank, and I'd blame Luna first. I'm from another Equestria. One where Cadista didn't contact us or maybe even existed so your dream for me became reality. Luna can fill you on the details.” Celestia just shook her head.
“Oh yes, my sister will since she was the one that hinted I should visit. Now what are you working on Princess Twilight?” Twilight rolled her eyes and the title which got Celestia smiling. Twilight walked over to the board and books.
“Trying to reconstruct my spell and later it to try to get back home. I have duties there after all. Princess of Friendship and your Twilight seems to have things handled here.”
“That she does, she hasn't quite fulfilled what I planned for her but in many ways she has succeeded on things beyond my wildest dreams. I'm proud of her, just as I'm sure your Celestia is. Now would you like some assistance with this spell?”
“I would like that.” Celestia moved beside the smaller alicorn and done something she rather missed. Hours of studying magic with her.

Days later Twilight was in an empty room in the Phoenix Castle. With her was the other Twilight and her friends including Princess Luna. Princess Celestia wanted to be there but duties prevented her. Today was a big day. Today she hopefully returns home so they were all saying goodbye. When the group hug ended Rarity interrupted them all.
“Darling the girls and I though you should take these with you.” Her magic brought out saddle bags with Twilight's cutie mark. It was placed in front of Princess Twilight and she lifted the lid and found several pictures of her memories of good times including a couple taken during her stay here. “The other bag has the Gala gown I made for our Twilight.” Princess Twilight looked over to the other bag and held a dress she hasn't seen in a year. With tear filled eyes she looked to her other self.
“Why?”
“Call it a trade off. You lost Golden Oaks and everything in it. The pictures are all copies of the ones in the Library and the Gala dress, well I can't use it anymore and I'm sure your Rarity can modify it to fit your alicorn self.”
“Thank you, thank you all.” She rubbed her eyes. “Well let's get this show on the road.” Everypony else backed away as Twilight put the saddlebag on,closed her eyes and focused. While her eyes were closed she didn't see what happened to her. Her horn was surrounded her horn before flaring with magic and a white light covered the horn. Her mane and tail started flowing in a breeze her magic was creating. Energy bolts crossed around her then her eyes opened but had the solid white glow like when she used the Elements of Harmony. A white sphere forms but not around Twilight but above and a hoof or two in front of her. It grew large. Large enough to easily hold the Elements Bearers including the other Twilight and Rainbow Dash. Twilight knew something was going wrong but she couldn't stop the spell no matter how hard she tried. The sphere emitted a bright flash and Twilight heard a pair of thumps. Twilight was exhausted and was trying hard to stay awake. It was working and as she collapsed she saw a white furred mass in front of her in a familiar shape.
'Princess Celestia?' Twilight manage to think before darkness consumed her.
