Meanwhile, The whole team stood together “We won’t let you win!” said Lightning “No matter how powerful you get, it won’t make a difference.” His horn began to pulsate as his power increased… glowing brighter than ever before. “Oh, no you don’t, not this time.” thundered Sombra as he prepared to blast him, but Celestia and the Friendship Ponies stepped forth. “Oh, yes we do!” she snarled, and the Powers of Harmony began to glow, ensnaring him in magical lines. “Ah? What?!” he growled and roared unable to move.

“Let’s get him!” shouted Shining Armor. His wife agreed and they both charged at him and struck him hard, followed by Grand Ruler and Luna striking him again. Fratello charged up his weapons to full power. “FIRE!” and he blasted him hard. One-by-one, Lightning’s friends unleashed their finishers with all the power they had!

“WHIPLASH STRIKE”

“SUPER STAFF SPIN”

“THRASH SLASH”

“BOOM-BOOM FLARE”

Starla aimed with her bow “This is for what you did to me back on the ship! GALACTIC PROJECTILE” She fired it right at the dark crystal heart, making Sombra screech in extreme agony. “My turn…!” sneered Lightning “Time to finish what I started back on the ship… UNIFORCE!!”

The blast hit Sombra, full force and making tons of giant explosions that seemed to engulf him, after which, the team was exceedingly exhausted, the fighters had only little power left in their suits. “We… did it…” panted Rarity.

“We won!” cried Artie.

Pinkie Pie sighed hard and fell flat on the ground. “Whew! I’m glad that’s over I’m pooped!”

Something didn’t feel right, however. The darkness was still growing, and all the monsters hadn’t disappeared. The reason was obvious and answered as they all heard a soft, and wicked hissing coming from within the smoke. Fluttershy felt shivers run all over her body as she gazed for as the smoke cleared.

(Exactly like this)

“N-N-No…! It can’t be!” she squeaked “I… It’s… IT’S…”

“…SOMBRA!!” Rarity screamed. Everyone gawked, gasping in horror as Sombra stood there, a little bruised and battered, but not at all beaten. He just stood there snickering at them. “Impossible!” sneered Celestia “Nothing could have survived that!” added Luna.

“You just never learn, do you?” hissed Sombra and he explained, proving Cadance’s worst fears had come true! As long as he had the crystal heart, and the darkness continued to grow he would be virtually unstoppable against all of their best forces. “Now then, who shall be first to go? I think I’ll start with the metallic one.” He raised his claw and magically levitated Fratello high up into the air.

“FRATELLO…!!” screamed Cadance.

“NO! DON’T DO IT, SOMBRA!!” shouted Celestia.

Sombra narrowed his eyes and fired a powerful blast right up at the defenseless robot. “…CADANCE!!” Fratello shouted as he exploded in a huge ball of fire and bits and pieces of him went flying all over the place. Cadance fell to her knees and burst into tears of anger and sorrow “…NOOOOOOOOOOO!! Not again!”

Blazes of fury filled everyone’s eyes and they all lunged at Sombra, forgetting that they were still low in power and tried from all the fighting and using up so much power. Sombra easily smashed, booted, and struck everyone hard…. Lightning’s team and the friendship ponies, their suits powered down form all the weakness. Celestia and Grand Ruler rushed at Sombra together, colliding into him with such force, determined to get at him for killing their nephew-- Cadance’s brother, but they too had used up a lot of power in the battle and were easily over powered and shoved back hard, skidding across the ground!

Lightning was livid to have seen such a thing… and his fury only worsened as things continued. One-by-one Sombra went after the others, ruthlessly attacking them and really hurting them. Krysta and her fairies flew over just in time to see almost all the friends lying sore, battered, and weak from such beatings, and they were shocked and livid… but Lightning, he had seen enough and bolted up right shouting “ENOUGH!!”

Sombra turned to face him and laughed “Take a good look at your pitiful friends now, brave admiral.” And he blasted all the others with powerful shockwaves making them holler and wail in agony which only further infuriated Lightning. His blood was boiling so hot and his heart was pounding just like his head with blazing fury…

The fairies decided to try and help the fallen friends out, but Sombra fired a few warning blasts telling them “Keep out of my way!” and he continued to harm the fallen ones. “Darkness is all! Suffering is the key to ruling everything! This world… the universe… I will make it all suffer and wail and rule it all for myself!!”

"I don't think so." a voice claimed.

"What?" Sombra snarled. Even in their weakened state, the whole team could see Sapphire, Mykan, the changelings, dragons and Kyara in a large bubble of magic.

(It's basically this)

Sombra growled and he and the minions blasted the bubble with all of their magic, but the bubble deflected the blast. "How is this possible?" Sombra snarled.

They friends came down in front of the fallen fighters and the bubble disappeared. "You may have your dark magic, but we carry the most powerful magic of all; the Magic of Friendship."

Frost snarled. "Let's get them!"

He and his comrades roared and charged at Sapphire. She blasted them hard with a rainbow beam. The force of it actually destroyed the dark crystal heart pieces inside the minions, destroying them as well. Sombra and the entire team were shocked. "Impossible." he cried.

“She destroyed them with one hit! Wicked!” Pharynx exclaimed.

Sapphire turned to him. "You're turn now, Sombra." Sapphire turned to her friends. “You guys get the team to the palace so they can heal. I’ll deal with Sombra.”

“Right, come on gang, you heard her.” Mykan ordered. The friends carried the team to the palace and away from the battle scene.

Sombra snarled and charged Sapphire. She zipped out of the way and blasted him hard with her magic at the crystal heart. He screamed in pain. Sapphire lunged and rapidly punched and kicked Sombra.

Sapphire unleashed a furious wave of power as she screamed “IT’S OVER, SOMBRA!!!!”

“Come and get me!” roared Sombra and he lunged right at his with her fists ready, he thrust them forward, but Sapphire simply raised one fist, coated it in magic and punched her fists upward, and then socked him hard in the gut with his other hand sending him crashing through a row of trees, one after another.

Sombra burst through the fallen trees to find Sapphire standing before him, and before he could react, Sapphire kicked him up high into the air. Sapphire took off and after him and kicked him hard again sending him slamming down towards the ground, but Sombra stopped at the last few inches by flapping his wings and zoomed right back at Sapphire colliding into him hard, and he punched her hard in the face, and tried to blast her with a powerful beam, but Lightning countered with a beam of his own forcing it back at him! “You’ll discover that I’m no pushover this time!” Sapphire growled and lunged at Sombra aiming to punch him, but Sombra caught his fist and punched him hard, but Sapphire winced in pain, but she managed to kicked him.

The two creatures brawled furiously, swiftly swinging their fists and feet. Blasting each other and colliding into one another forcefully, but the more the battle progressed; Sombra got hit more and more and was really taking a lot of damage, while Lightning did get hit and blasted at as well, he didn’t seem to take as much damage as Sombra did, much to his annoyance and confusion. “This… this cannot be! No one should be able to stand up to me! Who are you? What are you?”

Sapphire snickered “What? You can’t figure it out?” She stood in midair tall and proud and proclaimed “I am… the bane of evil’s existence, the sworn protector of all that is good and decent. I am the answer to all problems, a hero to those in danger who cry out for help. My name… is Sapphire Shimmer!”

Sombra never thought he could feel so furious ever. “Curse you! Curse you, it can’t be!” he looked as if he were about to explode, but really it was his power increasing with the impending darkness. “I have come too far to face defeat again! I will defeat you, human!” He only had one option left if there was any hope for him to combat Lightning. He began to absorb the powers and magic of all the monsters he had resurrected. “Yes! Yes, I can feel it! Prepare to witness true power like never before!” he snarled as he was enveloped in dark flares. “First I will smash you, and then your planet will follow!”

“Bring it on! I’m ready for you!” growled Lightning, and the fight continued. This time, Sombra put up more of a fight than ever and managed to bash Sapphire back harder than ever, and match his magic strengths as well, but Sapphire refused to give in.

Their battle was so fierce that it could be seen from all over, even at the palace. Goldwin hadn’t budged from his telescope at all. “Wow! I don’t think I’ve ever seen a more fierce fight before.” Mykan and Snowflake were also mesmerized by the battle. "Get him Sapphire!" Mykan cheered, even though Sapphire was WAY too far away to hear it.

The others were resting in the sickbay, recovering quickly, and they could look through the windows and see the distant explosions and bright lights from collisions of the two fighters. “Look at them go!” cried Spike.

“Do you think Lightning can win this battle all on his own?” asked Artie.

“…Possibly.” Grand Ruler said.

“Possibly?” asked Celestia.

“Well, is there any way we can help her?” asked Rainbow Dash.

“There just may be, but it is very risky. It must only be done at the right time and in the right place.”

The others each voiced their volunteering to take the risk if need be as it would most likely be their one and only chance to get rid of Sombra once and for all. The fate of the planet depending on it!

Snowflake roared and flew out the window. "Snowflake, what are you doing?" Rainbow cried. Mykan saw her heading towards the battle. "She going to the battle and so am I." Mykan replied and he too flew out the window. "Are they crazy?" Fluttershy squeaked. "Nope, they're just loyal." Pharynx replied with a smirk.

Sombra and Sapphire continued to brawl, colliding into one another. Their fists and feet swinging, and rapid shots of magic blasts.

In a huge explosion, they both fell to the ground away from one another, they both were looking battered and bruised, but they both got to their feet and stared each other down. “You dare to continue?” growled Sombra “You are either brave, or more foolish than I gave you credit for.”

“It’s you who’s the fool.” Sapphire sneered “All you use your power and resources for is your own greedy reasons. If you had ever learned some sense in your life, maybe things would have turned out better for you.”

“Spare me the heartfelt chattering!” he then gazed down at the large hole leading into the dark dimension. “Do you see that? The darkness is growing, little human! Nothing can stop it! Not you, nor anyone else in this world. Many before you have tried, and they got exactly what they deserved… and you will soon follow!”

Sapphire wasn't going to give up now. She lunged at Sombra and aimed to punch him, but Sombra zipped out of sight and suddenly kicked her in the side, tackling her to the ground, and ramming numerous punches at her face until Sapphire blasted him off and into the air. “Oh, really, try this!” growled Sombra, and by magic his horns glowed and extended gripping Sapphire tightly.

Sombra laughed and then bashed and smashed Sapphire around like a hammer before reeling her and punching her back out again. Then reeling him in again, and socking him again… and again… and again…

Finally, Sapphire grabbed the end of Sombra’s horns and pulled on them with all his might, which Sombra felt “Oh, no, you don’t!” he growled as he fired multiple shots at him, but Sapphire refused to let go and managed to snap one of the horns in two, freeing himself. She softly floated to the ground panting heavily, while Sombra retracted his horns, one of them now broken making him furious “I’ve had just about enough of this!”

“And I’ve had just enough of you!” growled Sapphire “What say we finish this off once and for all?”

“For once we agree on something.” hissed Sombra and he began to coat himself in all the dark magic he had and Sapphire did the same. “This is it. I hope this works. It’s all the power I can spare.” He muttered to himself. Sombra roared and charged Sapphier at full speed Sapphire charged Sombra at the same speed. The two forces collided.

KA-BOOM!

The explosion was so big it could be seen from everywhere on the planet!

A huge burst of light shone clear up into the skies, nearly piercing the darkness. Many of the civilians in the villages nearby gazed at the light in awe and wondering what it was, and everyone could see it form the palace too. “There!” snapped Grand Ruler “That must be it.”

As everyone was no fully healed, it was time for them to head out.

…

The light had ceased, and the hole leading to the dark dimension was going crazy, as if that last burst of power had disrupted the dimension within, destabilizing it.

When the smoke had cleared, there was Sapphire and Sombra lying flat on the ground, looking really injured. Suddenly, they both twitched and painful staggered to their feet. Sombra sneered. “You pitiful creature. You squandered your power and life and look where it left you…”

Sapphire's glow had gone down immensely after the collision and from fighting for so long. Sombra walked closer towards her snickering, and stood only a few feet away from the unstable entry in the ground. “For the record, you’ve been a very worthy adversary. It’s almost shameful it must end like this. Any final words?”

“Yes…five…” hissed Sapphire. “…I am not beaten yet!”

Sombra laughed “You fool! What more can you possibly do to me? Even with your magic, you’ve no power left. You’re all alone, and about to be erased forever!”

“You’re wrong! He’s not the one who is alone.” called a voice from way back behind Sapphire. Grand Ruler marched forth, and Celestia marched alongside him, and one by one all the others marched alongside them, backed up by the entire army. Her glowing smiled brightened.

One by one, every one of his friends spoke severely to Sombra…

Starla… “You’re a vile demon!”

Buddy Rose… “You terrorize others for your own amusement.”

Artie… “You bring nothing but sorrow, misery, and pain wherever you go.”

Rhymey…

“But no matter how hard you fight,
Evil will never triumph over right!”

Dyno… “You are disgusting!”

Myte… “You are despicable!”

Rarity… “You’re the kind of evil that gives hooligans and ruffians that I scoff at a bad name!”

Pinkie… “But there’s still one ultimate weakness you have, and it’s our greatest strength!”

Rainbow Dash… “We’re never alone! We’ll always have each other.”

Fluttershy… “And even if we can’t really be there for one another…”

Applejack… “We’re with each other in spirit, and that’s somethin’ you’ll never understand.”

Spike… “Yeah, what they said!”

Krysta simply nodded bravely as did Shining Armor, Cadance, and Luna.

Lightning turned to face Sombra, who didn’t seem amused at all. “Ha!” he scoffed “I’ve heard enough of these petty speeches and preaches of friendship!” he began to power up to destroy them all. “Behold what real power is all about!”

Suddenly, Snowflake dove in a blasted Sombra hard with her plasma blast, knocking him to the ground and stopping his attack. Snowflake landed near Sapphire. "Alright, girl. Let's do it." Sapphire mounted Snowflake just as Sombra stood up. "YOU INSOLENT PESTS!" He fired a pulse at them but Snowflake took to the skies. Sombra flew up after them.

"Let's show him, what we can do, girl." Sapphire said. Snowflake nodded. Sombra fired more pulses at them, and Snowflake dodged them with ease. Sapphire retaliated by blasting her own pulses at Sombra, which made their mark. Sombra fell to the ground, hard. Snowflake roared and dove towards Sombra. He grunted as he saw the Light Fury coming closer towards him. At the last second, Snowflake blasted him with her plasma blast.

BOOM!

Sombra screamed in pain. Snowflake landed in front of the army and Sapphire dismounted her. Sombra struggled to his feet. He growled in fury and he began to power up to destroy them all. "TIME TO DIE!" he yelled.

"I don't think so." Sapphire replied. Using the elements bestowed upon her, she created the bubble again and floated into the air. That's when the friendship ponies and Celestia changed into their Valkyire forms. Their shields went up to Sapphire. Mykan, Kyara, the changelings and dragons appeared and entered the bubble. "Need some extra power?" Mykan smirked.

Sapphire smiled. "Let's end this!"

The shields circled the friends as the held hands or wings with each other. Sombra fired his biggest, most deadly burst of dark magic straight up at the friends. They countered with "HARMONIC CONVERGENCE!" the blast was twice as large as Sombra's and easily overpowered his attack, heading straight for him.

“…NO!!” He screeched as the magic consumed him, shattering the crystal heart shard into dust, and breaking up his demon body, changing him back into the dark smoggy spirit he was. In a fierce and bright explosion, everyone flew backwards falling off their feet.

All the swirling darkness vanished leaving clear skies again, and the hole in the ground had sealed, and all was quiet.

All the fighters recovered and snapped themselves awake. “Whoa! What happened?” asked Starla.

Princess Luna gazed forth. “Sombra’s evil, and all that power. It must’ve overloaded the dark dimension causing it to collapse.”

“So, he’s gone, really gone?” asked Rainbow.

“Looks like it.” said Applejack.

The friends floated down and the bubble once again disappeared. That was when the chest from the Tree of Harmony came in front of the gang. "What's the chest doing here?" Pyrax asked.

The chest floated over New Ponyville and over Twilight's old home, the Golden Oak Library. It was condemned when she passed away. The chest and the tree were both glowing as the tree absorbed the chest. The gang arrived at the tree just in time for a bright flash. Everyone covered their eyes. When the light diminished, what everybody saw made the gasp in awe.

The Golden Oak Library turned into a castle. The tree-castle bears some resemblance to the library, however, is many times larger and appears to have a multi-level castle in its branches, which includes a great balcony, two spires, and a tower. The structure has at least one banner flying on the side marked with and the top bears a large crystal star.

Two sets of five strings of beads hang off the side of the structure much like the white beads that hang off the Tree of Harmony. At the foot is a great golden stair for the two-leaved golden door into the tree's body. Two open lancet windows flank the door.

The lobby's two stairs lead into the castle rooms where lancet two-toned green glass windows and crystalline lathed columns with scrolled tops line the hall decked by a brown rug with scrollwork.

"Sweet Celestia! Are you all seeing what I'm seeing?" Rarity asked.

"The chest turned Twilight's library into a castle?!" Pinkie exclaimed in shock.

Even their majesties were shocked. "But whose is it?" Sapphire asked.

"I believe it is yours Princess Sapphire." Twilight's angel-corn said as she appeared. Everybody was amazed.

"It's mine?!" Sapphire repeated. Twilight smiled. "You deserve it. You and your friends defeated King Sombra and saved the universe from his darkness."

Grand Ruler came forth. "Indeed. You and your friends are the heroes today."

"While we're on the subject." Lightning added. He cleared his throat. "... WHEN DID CHANGELINGS METAMORPHOSED!" The outburst surprised the gang, but they too were shocked and confused. "We'll explain that later, but how about we check out Sapphire's new castle?" Mykan suggested.

Everybody immediately rushed into the castle. There was a large library, almost as large as the one in New Canterlot. At its end is a golden-framed green glass fanlight door to the throne room that have a crystalline throne about a star-shaped dais on a golden dish on a violet rug with scrollwork. Even with its door are a set of green glass spire lights.

Also, it contained high-rising ceilings, long hallways, and a dining hall. “It’s gorgeous!” Rarity cried.

“Indeed.” their majesties added.

Rainbow elbowed Sapphire playfully. “Looks like somebody has a new home.”

Sapphire smiled. Now she has a new home.
