The next day,
The sun shines brightly over Canterlot as Four Princesses stand on its tallest tower balcony. Celestia and Luna have once again dawned their crowns and hoof guards as they overlook the last of the citizens evacuating the city. Earlier that day, multiple Portals had been set up in Canterlot to ensure that every pony could get to where they wanted. However, no pony forced anyone to go where they did not wish to. Slowly one by one the Portals start closing as the last of the ponies gather around the remaining Portals.
Discord stands near the Chaos Dimension Portal holding a sleeping Fluttershy in his arms. He waits for the last of the ponies to enter his Portal before he takes one last look at Princess Twilight and enters the Portal closing it behind him. And with that, there are only four living creatures left in Canterlot. Most of the ponies choose to go to the other dimensions with a select few going with the Crystal Empire to be banished earlier that day.
Twilight releases a sigh of relief knowing that her little ponies are now safe. But somewhere in the back of her mind, she believes that not everypony got to safety. With all the chaos and destruction that has occurred, there's no way she could have kept track of every pony. She can only pray that every pony got to safety before the Portals closed.
Twilight looks over her shoulder to the others, “Have all the preparations been complete?”
“Indeed, they have. We can safely say even if Luna and I were to perish. The sun and moon shall move normally,” Celestia says before taking one look at her sun, “although a part of me does wonders why I never thought of doing this earlier in my life,”
“It's because you enjoyed your job sister,” Luna chimes in, “as such, you never had a reason to find a way to get that ball in the sky to move on its own,”
“Can I ask how you two did that?” Cadence asks,
“We did some modifications to the medallion we gave Twilight during her coordination as the rule of Equestria,” Celestria says, “So long as it's not destroyed, there shall be no problems with the sun or moon,”
“And you have it here. On the frontlines. Where could it get destroyed in the aftermath of our battle?”
“Cadence. I am stung,” Celestria puts a hoof to her chest in a hurtful gesture, “how could you think so little of me? Of course, I didn't leave it here where it could be destroyed,”
“That's good to hear,”
“I left it in the Chaos Dimension,”
“That doesn't fill me with confidence,”
“Relaxed fellow Princess,”, Luna reassures her, “no pony can break the medallion by simply sitting on it,” Luna says before looking at her sister, “Unless you are my sister,”
“That's rig- HAY!”
“Girls I believe we're getting off-topic here,” Twilight stops them before they have another battle to deal with before the fight with The World Eater, “Have you gathered all the relics in Equestria?”
“Yes, they're in the throne room ready and waiting for us,” Celestia says as they make their way to the throne room.
Once there, Twilight feels a bit of nostalgia coming over her. The throne room is filled with magical items of great historical value to the smallest item ever enchanted. Many of these items she has no clue of where they came from. While a select few she can remember who they belong to and what adventures she and her friends had to go through to acquire them. In a way, it's almost poetic, how her final battle will begin.
This is where it all started for her. This is where she got her cutie mark and became Princess Celestia’s student. This is where she became a Princess before becoming ruler of all Equestria. And now this is where she shall make her last stand fighting the greatest monster that ever roamed Equestria.
Twilight takes her seat on the throne as the others stand nearby waiting. She composes herself before addressing her fellow Princesses,
“Princess Celestia, Princess Luna, and Princess Cadance. This is your last chance to go with the others. Nopony will blame you for not wanting to die here. This is my battle to fight, not yours,”
“Princess Twilight Sparkles,” Celestia says smiling at her old friend, “I believe I speak for every pony here when I say. We already made our decisions when we decided to join you on this mountain,”
“This will be the grandest fight in our lives,”
“We are all that stands between that thing and the end of the world,”
“If that's what you want, then I cannot stop you,” Twilight says relieved that she doesn't have to fight this creature alone, “let's go over the plan again,” Twilight summons a chalkboard with drawings of them in step-by-step progress of fight The World Eater,
“Once The Unity Crystal has been created. We will draw The World Eater to the mountainside of Canterlot, where it will expose most of its body while trying to climb it. Princess Luna and Candance. You two will be flying around the creature distracting it. Use whatever you can, but don’t get close to it. We can’t risk anypony getting hurt earlier on in this fight,”
“While I am channeling the power of the Unity Crystal, I will not be able to defend myself. So, Princess Celestia will have to protect me in case the creature decides to come after me. Once it’s ready, everypony will regroup to me and cast their strongest shield spell to enter The World Eater's mouth. Once inside the creature, it will take me a few seconds to set off the magic storage in the crystal. Killing the creature in one blow along with us,” Twilights says before turning the chalkboard around showing a diagram of The World Eater and highlighting points around its body,
“Although this sounds easy, there are a few factors we must take into consideration. Although The World Eater is rather large, do not underestimate it. The World Eater's jaws are strong enough that they can rip apart stone as if it were candy. Not to mention it has the reflexes of Apex Predator. No ponies have ever been able to escape its bite as of yet. If we miss our timing, The World Eater will kill us before we have a chance to set off The Unity Crystal.”
“There will be no second chances. We only have one shot to get this right otherwise every pony we know, and love can never come back home. Does everypony understand what they need to do?” They nod in agreement as Twilight readies herself, “Very well then. Let us begin,”
Twilight joins the other Princesses in the middle of the throne room as they stand in a cross formation facing each other. They close their eyes as they focus on their magic and all the magic around them. Slowly each magical artifact around them started glowing with magic, bringing the room to life in a rainbow color hue.
Across Equestria, wild creatures all look in the same direction as they can feel that something is happening. In another dimension, Discord sets Fluttershy down by a tree before his body shivers as he looks out into the distance. In an unknown forest, a lone pony tries to find her way home before she too also looks in the same direction as the other creatures.
Back in the throne room, a Galaxy of Rainbow Magic started swirling in the center of the princesses before expanding to cover all of Canterlot and the surrounding area. Then slowly mist of tethers like magic of different vibrant colors flows to the center of the Galaxy. They came from everywhere, trees, animals, and the magic artifacts surrounding the Princesses. These tethers were moving at a steady pace before picking up speed. The Princess struggles to handle the magical power as they start to begin to focus the energy on one pony.
Twilight grits her teeth as the Magic Galaxy slowly moves towards her making her the center of all the magic. Magic tethers from the other princesses slowly start sipping out of them and flowing to Twilight.
In the Ever-Free Forest, a gigantic creature consumes a defeated hydra before it also looks toward Canterlot blood dripping down its face.
Slowly one by one, each artifact lost its glow as its magic left itself depowering it forever. Discord looks at his claw feeling his magic slipping away. Queen Opaline panics as she feels what little magic she has left, slowly leaving her. Princess Cadence was the first to lose her magic as she took a knee on the floor, as she catches her breath. Soon after Princess Luna joined her followed by Princess Celestia. They watch in awe as every ounce of magic in existence flows into Twilight.
Twilight struggles to handle the magic surging through her body as she concentrates it into her horn. Slowly the Magic Galaxy condenses before their eyes, forming The Unity Crystal.
At first, it looked like it was an Aqua-colored Crystal in the shape of a horseshoe with wings on the side. But then another Crystal was formed alongside it. A clear White crystal in the shape of a circle And then a Dark Blue arrowhead-shaped crystal was also made with them. Once these Crystals have been solidified, Twilight catches her breath as her magic has also been taken by The Unity Crystal.
Slowly the crystals spin in the air before they move close to each other and join together as one. The circle crystal being in the centerpiece was surrounded by the winged crystal horseshoe with the opening facing upward. And finally, the Arrowhead crystal stands on top of them with the pointed end facing the sky.
Once combined they send a rainbow of magic into the sky spreading magic throughout Equestria more powerful than ever before. Each princess stands up as magic flows through their bodies once again filling them with strength. They stare in awe at The Unity Crystal slowly spinning before their eyes.
“It's beautiful,” Princess Cadence says as the others nodded in agreement,
“To be honest,” Princess Luna says, “it is much smaller than I expected,”
“That's because it is very concentrated,” Princess Celestria says proudly, “isn't that right Twilight?”
“Indeed, it is but this is so much greater than my expectations. I never imagined that The Unity Crystal could have this much power,”
“Is it strong enough that we might be able to have a change of plans?” Princess Cadence says as the others give her questionable looks, “Just asking,”
“I don't think so,” Twilight says bringing the crystal close to her and observing it, “But I can guarantee that the plan has a 95% chance of success now,”
“Twilight,” Luna speaks up, “how much time will you need to get The Unity Crystal ready?”
“I'll need at least 30 minutes to fully understand The Unity Crystal before I set it off,”
A massive roar shakes the ground they stand on as they look to the entrance of the throne room knowing what is coming. “You got 20,”
All four Princesses fly above the streets of Canterlot as they see The World Eater running straight towards them. It destroys the land with every step it takes ruining railroad tracks, and streams of water and uprooting any unfortunate tree that didn’t get trampled.
They would be called liars if they were to say that they were not scared. But that's part of being courageous. Knowing that you are afraid but are still willing to face death regardless of your fears. And right now, death charges at them at frightening speeds,
Twilight looks at the princesses remembering how she met each one of them. Flashes of her life flash before her eyes as she remembers all the adventures she had with her family and friends. All the happy tears, the hard times, and the last moment she spent with them. A tear goes down her face as she wipes away smiling as the others do the same.
She may not have wanted to live the life of being a hero or a princess, but here she is standing with three of the strongest princesses in Equestria. All of them were willing to lay down their life to save their fellow pony herself included. Here she stands with her family and friends at the end of their lives.
If given the chance. Twilight would do it all over again. And not change a single thing. Well, maybe a couple of things.
Twilight starts focusing her magic on The Unity Crystals as the other princesses prepare for battle. What happened next was a fight to be told in stories passed down from generation to generation. The last stand of the Princesses of Equestria versus The World Eater with one final battle cry.
“FOR OUR LITTLE PONIES!”
