Back at the Crystal Empire and the Schoolhouse, every Crystal Guard, Gemstone, Shining Armor, Luna and now Celestia have rallied all their troops, Weaponry and Forbidden Powers to take the fight against Sombra and to return Equestria. Since Spinel, Bort, Phos, Diamond and the Mane 5 all headed back to Equestria, they had to defend themselves, but maybe also find a way to take the Empire back.
"Attention all! We know we haven't planned much after Sombra's attack and take over, but without the Element of Magic, we'll take the fight to them! Crystal Guards, Lustrous, all that'll help us to take back the Crystal Empire and then take back the whole of Equestria!" They all then cheered at the Princesses Speech. "Toward to battle! Charge!" They all then rushed towards the Empire, fighting off the other guards that may get in their way, towards the main Spire of the Empire. Once Shining, Luna and Celestia all got inside the throne room, they were greeted by silence and emptiness. "It's quiet. To quiet!" Luna replied, not thinking Sombra would return, however, that ended quickly.
Their was a quick shaking through out the main throne room, as Sombra returned from the Smoke, however, they saw he was different, as he looked shattered, almost like a Gemstone. "Sombra!" Sombra then looked at the Royal Sisters and the Prince of the Crystal Empire. "So... You sent Gemstones to Destroy me? You all are delusional!" They didn't know what he did to them, only to think he did something. "But, if you did want to face me as a monster, why don't I give you all that!"
They didn't understand what he was talking about, only for him to grow inside, as he took more of a Centaur form. "Sombra, Cease your Plan!" Celestia ordered, only for him to ignore it. "I should of left you to dead! Behold, the new Lord of Equestria!" He then started laughing, as he then jumped off the Balcony as they watched. "Darling!" Cadence yelled out, only to see the Dark Red glow and fog them growing in size, making them all scared.
"What is he doing?" Luna asked. "He's preparing to fight, in a form we never faced him before!" Shining saw what he was turning into, seeing some shine from his Body, almost looking like a much larger version of his Crystals. "Spinel, where are you?"
Meanwhile in the outskirts of the Empire, Twilight used her Magic to teleport everyone, as they also saw the giant cloud behind them. "What is that?" Diamond asked. "It's Sombra! I never seen him do anything like that before!" "If being a gemstone and Cutting it changes it shape, then I don't know what shape he'll be in!" "Maybe a Diamond?" Pinkie Pie said, trying to lighten the mood, as they then looked at what Sombra had become.
Once the Fog lifted, Sombra was in a new form, being a large Centaur with a polished flat Surface, still looking like a Gemstone he was now. He then opened his Red eyes, which also got a Diamond shine to it. "You all dare face me? Who's first!" He then jumped up his front legs and roared, as everyone knows they can't face him in that size.
Spinel, The Gemstones and Mane six weren't going to let it happen, as Spinel came up with a plan. "Bort, I need Rainbow Dash to..." Just then, Bort then just jumped off the cliff they're standing on. "...Just jump off the cliff?" Pinkie Pie replied. "I don't care, I'm going to smash him!" Rainbow Dash said, as she then flew upwards and went to face Sombra herself. "I'm sorry about this, but maybe we can just do things in two different groups." Twilight said to Spinel, as Spinel understood, as they then jumped off the cliff, including Phos and Diamond. "Ok girls, we need to get Rainbow Dash back."
Rainbow Dash flew towards Sombra, who then saw her and started swatting her, annoying him. "You Mane Freaks have been a thorn in my side for a while now, not like those Gemstones!" "Huh?" What he said made Rainbow Dash confused, which gave him the adventage to swat her out of the Sky. "SOMBRA!" Bort then came up rushing towards him, as he then looked down at them. "Homewrecker!" "Oh, the Black one!" He then used his hand to attack them, which ended up flicking them away. "I felt like Hardness of theirs."
Twilight and her friends caught Rainbow Dash and recurred their Magic, as they tried using a Magic Blast of Friendship, only to be reflected somewhere else due to his body being Crystals now. "It-It didn't work?" Twilight asked, only for her and her friends to be pushed back.
Spinel then saw something that they're not doing. "Everyone, I know what's going wrong! Like you Six, we're not working together as a group! Think about it. Your Elements, our Fighting Skills, both powerful, but when we use our Powers together, we might save the Entire of Equestria!" Twilight knew what they ment. "Your right! We're just doing our individual fighting skills, but we should of just teamed up in the first place!" Bort then returned to them all, being scratched up a little. "Hate to say it, but your all right. This is our time, we're the Hope!"
They all then got ready to fight Sombra, with Spinel and Twilight in front of the group. "This is our time! Our Moment!"
Sombra looked down at them all, seeing they were now teaming up with each other. "Looks like the battle now now started! Corruptous, Destroy them!" He then snapped his fingers, which ended up with many Corruptous coming out and attacking, but the Mane 6 and Gemstones made easy work of them. "Now, we have to find his weak spot!" "Maybe the Head?" They all got confused. "The head?" "That's always a Lunarians Weakness from our world!" "But we're not in our world, Bort!" Spinel replied as Sombra then yelled out. "GEMSTONES!"
Spinel then realised something about what he said. "Gemstones? What is he talking about?" Fluttershy asked. "It's us. We're the weakness!" Spinel said, as the Mane 6 were still not getting it. "Think about it. we have been in this guys head ever since we got here. Maybe if I get his attention..." That'll give him time to be Vulnerable! Nice idea Spinel!" Twilight complemented them. "Ok everyone, Split up!" Just then, everyone then splitted up in different directions of the Empire, making Sombra confused.
"Hey Sombra!" Sombra then saw Spinel with Twilight. "You want us? Come and get us!" "You don't give the king orders! I GIVE MYSELF ORDERS!" He then stomped him way towards both of them, as Twilight then carried Spinel away. "We should of thought of this sooner!" "Trust me, this was my plan!" As Sombra was following them, the Gemstones and Mane 5 all were after him, after one thing.
As Sombra was chasing the Princess of Friendship and Gemstone, he grew a little tired. "So, what was your plan is we weren't here? You have the Empire, Equestria, Cadence, what more could you ask for?" Spinel asked him, as he then growled at them. "Once I rule both Canterlot and the Crystal Empire, I'll wage a war against the other Kingdoms of Equestria! I'll rule the Sea Ponies, Griffons, Yaks and... You may think that would be enough? Here's the fun fact once I'm done with you. You'll be me and my Wife's Wedding Rings!" Spinel understood what he was talking about, as he still didn't know about one thing.
"I'm the new King of Equestria! I'm all powerful, all seeing, all knowing!" Just then, he looked down, finding Rainbow Dash and Fluttershy carring Diamond and Bort, as both were struggling with them both. "Man, your heavy!" "I know! We're Gemstones!" Both then dropped both Gemstones, as both then brought out their weapons and cut off the Crystal Heart, acting like a Pendant on his Chest. Once it was out, he felt a sharp pain. Before anyone could grab it, he then kicked it back to the Crystal Empire, as he also swatted both Pegasi and Diamond Family Gemstones back to Spinel and Twilight. "Did we win?" "Not Yet. But maybe if we can beat him there." Twilight said as she teleported them back to the Empire.
Back at the Spire, Phos, Pinkie Pie, Rarity, and Applejack all waited for them to return, only to be greeted by the Crystal Heart. "There!" Phos then took the Heart and rushed back to them, as Spinel and the rest came back. "Now, place the heart in the middle. That'll sort out this mess!" Twilight explained to Phos, as they did that, only to find out nothing happened. "Wha-What's happening?" Spinel and Twilight look the Heart, only for it to end up being Split in Half. "No... no." Twilight said with Despair.
They then heard chuckling in the throne room, which then made them mad. Spinel and the Gemstones took front as defence, as they headed up to the throne room in anger. Their were many Corruptous, but were taken out quickly, due to the Gemstones full rage. Cadence was greeting them, as she wanted to be their hostest. "I see my Love and King would like to see you..." Before she finished, Phos then gave her a swift punch to the nose. "You punched my Love? Now you made a mistake!"
Sombra then arrived back on his throne, as they all saw his Body was more Shattered than before. "You Gemstones have Taken everything from me! My Army! My Knights! My Armor! EVERYTHING!" "And you have taken us away from our home!" Spinel explained to him, as the Mane 6 came up behind the Gemstones. "Well, whatever happens next, just to let you all know... this was on all of you!" Sombra then threatened, as he was charging his Magic, only for the Mane 6 to charge their Friendship.
Sombra then gave a chuckle. "You think your Magic trick can stop me? HA! You all saw what happened when you used it on a Gemstone!" They remembered, as they also remembered what they did to Spinel the first time they met. "Aim out Magic at Spinel!" Twilight was confused, as the others know. "What?" "We used our Magic on Spinel the first time they freed us. Without you, it almost shattered them!" Twilight remembered the Spell. "The Prismatic Beam of Harmony? No one can withstand that Spell, not even the Pillars." "Twi, trust us." Applejack said, as Spinel understood what the plan was and was ready themselves.
"Honesty!" Applejack then fired an Orange Beam at Spinel's Shield, as the others followed. "Kindness!" "Laughter!" Fluttershy and Pinkie Pie fired a Pinkie and Blue Beam at Spinel's Shield, which they started to struggle a little. "Generosity!" "Loyalty!" Rarity and Rainbow Dash then fired a Purple and Red Beam at the Shield, as Spinel was then struggling much, as Twilight was the last one. "And MAGIC!" Twilight, being the full set the fired a Magenta Beam at the Shield, as Spinel was then ready to fire, as they started to struggle with that much Magic that they can't control.
As Sombra was ready to see Spinel Shatter, Phos then paniced and rushed over to help Spinel. "P-Phos?" "If your going down, I'm coming!" The Mane 6 saw that Phos will do anything to help them. Bort and Diamond saw that it wasn't enough as both then helped out also. Using much of their Strenth, they then pointed the Shield powered by Magic as Sombra, as he then grew more angry. "You all can't do this! Do you know what my Hardness is?!"
The Shield of Magic was now ready, as it was then ready to fight the beam of Light. "From what we learned, your a 0.5!" Spinel suggested, as the Gemstones then fired the Beam at Sombra, who was trying to crawl through it, as he did, he started to shatter and disintegrate. "It's over, Sombra!" Sombra then started to chuckle. "You haven't seen the last of me!" They then fired off all the Magic from the Shield, which then infused the entire throne room and through out the Entire Empire.
Once the light died down, the Empire was back to it's original state, as it was now a clear, sunny day, as plenty of the Snow had disappeared also. Due to that, everyone who's close to the Empire now got a Crystal Shine, including the Gemstones. "They-They did it!" Shining said proudly.
Back inside the throne room, the Mane 6 all got up, finding themselves now in their Crystal Coats. "D-Did it work?" Twilight asked, as she saw her friends now having Crystal Coats. The Gemstones looked at them, as they too obtained Crystal Coats. "We did do it. We saved everything!" Twilight and her friends then did the most biggest Group Hug ever, with the Gemstones too, as they did make sure not to crack them. "Does anyone think of this as crossing boundaries?" "You too?" "Nope." Diamond and Bort replied, as they were greeted by many familiar faces.
"Princess!" Twilight said as she then hugged Celestia, who was also freed by Sombra's influence. Shining then saw Cadence, freed from Sombra's Control. "Honey?" Cadence smiled, happy to see him again as he came over, got onto his knees and hugged her. "Thank you all!" Spinel was happy to see they were back together, as Phos brought both pieces of the Crystal Heart to them. "What about this?"
Spinel had an idea, as they took the pieces from them. "Maybe if I..." They then placed both pieces back together, as they then glowed and got forged back together, as it was also glowing in many of the Gemstone Colours. "You fixed it? How?" "Some Secrets are meant to be like that." Spinel replied, as they all laughed a little.
After the Threat of Sombra was over, Spinel, Phos, Bort and Diamond were being rewarded for their Bravery and for saving the Crystal Empire. They were then announced by all the Princesses and the Mane 6. "Citizens of Ponyville, Canterlot and the Crystal Empire! We are to here to Celebrate the Gemstones!" Everyone cheered as they looked at them. "The whole kingdom owes you 4 for what you have done. And for it, we give these Gifts to you."
Cadence started with Phos. "Phosphophyllite, or just Phos, even if you did steal the Crystal Heart from when you got here, you almost did start a fight against Sombra." Phos got embarrissed a little. "For it, I reward you with this Mini version of the Crystal Heart!" Cadence then placed a Ribbon around their Neck, which had a smaller Crystal Heart as the Pendant.
Celestia and Luna then did Bort and Diamond. "Diamond and Bort. Both did the Selfless and helped out your Gemstone Partners in a dire situation that they may not survived. To this, we reward you both with these." Luna gave Diamond a Shield with Sombra's emblem on it. "The Shield of Sombra, and to Bort." Bort then was given a Snow globe with a small Crystal Empire in it. "This Snow globe to remember the Empire you saved!" Bort was confused, as Phos and Diamond laughed a little, which annoyed them.
Both sisters then started laughing. "We're joking. This is really for you!" Spinel then gave them a Black Sword, made out of Sombra's Crystals. "Sombra's Sword!" Bort then tried to lift it up, only to struggle and was being difficult to stand, only for them to slam it into Diamond's Shield, shattering them both. "Oops." Damn it!" Bort growled as they took the Snow globe back, as it was Twilight's turn for Spinel.
"And to Spinel." Spinel then looked at the Princess. "You are a Hero of the Highest Level!" They then kneeled as Shining was going to knight them. "I here by dub you Spinel, Knight of the Realm!" The Entire Empire cheered after they were gifted, as Pinkie Pie brought out some Party Cannons. "What are we waiting for? Let's party!"
"Perhaps not!" Just then, they were greeted by Kongo. "Just remember why we're here Spinel. Because the threat of Sombra is over with." Spinel then remembered why they did this. "You have a request, Spinel?" Spinel looked at the Royals, as the Gemstones huddled around them. "We... Need to get back to our Universe." Spinel explained, as Celestia knew without Sombra's Magic was gone, they would have to leave. "Very well. With that, you all will be sent back on a one way trip." She announced, as the Mane 6 realised something. "You mean we can't see them again?" "It has to be that way, Princess."
Once they all were close with the Magic sending them back until Tomorrow, everyone was telling each other their final farewells. "Well, I guess this is it." Bort said, bringing out their hand to Rainbow Dash, only for her to end it in a hug. "Again?" "Sorry. Lost my cool there." Applejack laughed a little. "Even if we didn't get to know each other for that long, I'm glad their isn't only someone kind and Generous like me." "Y-Yeah." "Of Course Darling. But maybe I should name a clothing line after you all. 'Lustrous Gemstones'. Sounds good, don't you think?" Diamond and Fluttershy giggled at her idea.
"Even if we didn't get to celebrate a party for you, I'm hoping you all make something back in your world." "Maybe we'll have a small card game with the others. Maybe if Diamond and Euclase play fair." Pinkie Pie was interested in what it was like with Gemstones as Spinel and Twilight said their Goodbyes too. "Even if we did free you last, I learned plenty from you." "If our paths cross again, maybe come by to my Castle. We also have some work to fix our hometown." Spinel smiled as them and the Gemstones headed back to the Schoolhouse. The Mane 6 headed back to the Crystal Empire to stay for the night.
The next day, the Mane 6 were going to start Clean up of the Empire and Ponyville after Sombra's attack, but they were thinking if the Gemstones got home safe. They looked outside from the Balcony, to find the Schoolhouse was now gone, which made them sad a little. "Don't worry, maybe we'll see them again." Twilight tried to bring her friends hopes back, which it did. "Wonder what they're doing now?"
