Twilight and the others have waited about an hour for Shining Armor, Cadence and the Cutie Mark Crusaders to arrive. They all wondered if Spike had found Sarah or if King Sombra had found him first, little did they know that just a minute earlier in Sarah's room she had just taken a magical blast from Sombra's horn that was meant to kill Spike. When their friends did arrive the fillies ran up to them asking questions.
"Did you find it?" Apple Bloom asked. She really hoped that they found the heart so they could help Sarah.
"Is everypony alright." Sweetie Belle asked her sister.
"Tell us." Scootaloo said.
The group looked at each other and Fluttershy nodded as she held the box with the heart. "Yes, I have it." The Cutie Mark Crusaders smiled. They all seemed to so happy.
Rarity smiled at her little sister. "Yes Sweetie we are all alright. I hope you were good for Cadence and Shining Armor."
Cadence nodded. "They were angels. They were all glad that they could help you guys now."
Pinkie Pie smiled. "Yeah now we can finish this."
Twilight handed the Crystal heart to Cadence and she put it back where it went. They all knew that the magical power of the heart will not work unless the crystal ponies were happy. Shining Armor cleared his throat before he spoke. "We can't wait to make the crystal ponies happy. We must first stop Sombra and help our dragon friends. "
Rainbow dash nodded. "Yeah lets go." She went to fly straight into the castle but Applejack stopped her.
"Whoa there partner, don't go flying your tail in there all alone." Applejack told Rainbow dash.
Sweetie Belle smiled. "Yeah we are all going as a team."
The three fillies looked at each other and spoke. "Cutie Mark Crusades dragon savers."
Twilight looked at the fillies. She knew if she told them that they couldn't come with them then they would be really upset since they just wanted to help their friend who made sure they were taken care of when they were imprisoned. "It is going to be dangerous girls. I know that you want to help but we don't want you to get hurt. "
"We are going to help." Apple Bloom said stomping her hoof to the ground.
"Yeah danger is my middle name just RD." Scootaloo said.
Sweetie takes the pink cloak that was once Sarah's. "We are going and you can't stop us."
"Please girls think about this." Fluttershy said.
"We thought about it and we want to help. All for one and one for all. Right Cutie Mark Crusaders." Scootaloo said.
"Right!" Sweetie Belle and Apple Bloom replied.
Shining Armor looked at Twilight. "Twilight, they can come but let them stay behind us."
Cadence nodded. "Yes, that sounds right. Now we must hurry and use the spell to get rid of Sombra once and for all."
Everypony nodded and headed into the castle. They all hope they would find Sombra and get their in time before anypony gets hurt or does anything they would regret. Twilight lead the group as they ran though the castle, she used her magic to find Sombra saw he was in a room. It only took a few minutes but they got their and saw Spike holding an injured Sarah. Sombra stood close by the door.
"Sarah!!!" The Cutie Mark Crusaders said together.
"Is she okay? Sombra what did you do to her" Cadence asked worried.
Sombra chuckled. "I did nothing to hurt her on purpose. She jumped into my magic beam that was meant for the other dragon."
Spike nodded and a tear fell from his eye. "Its true, Twilight, shes hurt can you help her.."
Pinkie Pie jumped up and down. "Yes she can. We have her heart. Oh and this is for you Sombra." She threw a pie at him and it hit his face.
Twilight nodded. "Yes Spike I can but first we must use the spell to get rid of Sombra."
Sarah opened her eyes slowly. "Twilight..you wont be able to help me. I know the spell of which you speak of. It is called the heavenly light spell am I right?"
Shining Armor nodded. "Yes it is."
She nodded slowly at Shining Armor's response. "The spell will get rid of all the things he used his magic on including me.."
Spike looked at Twilight. "Then we can't do that."
Sombra chuckled as he wiped the pie that Pinkie threw at him off his face. "You can't get rid of me with out getting rid of the one who betrayed you but I can still get everypony here with out regret." His horn glowed and shot at them but Cadence created a shield to protect them.
Rarity looked at Twilight. "You go give Sarah her heart and try to help her. We will take care of this ruffian. "
Twilight nodded and at that moment all of the group except for Twilight and the CMC who wanted to check on Sarah, attacked Sombra. He used his magic and covered the floor with crystal. Rainbow dash flew around him to distract him while Pinkie pie brought out her party cannon.
Twilight and the CMC got by Spike and Sarah. They all looked concerned. "Sarah how do I give you back your heart?" Twilight asked.
Sarah's crystal on her necklace was still glowing dimly. "I..don't know..Sombra just used his magic and took it...ah..sorry it still hurts where he hit me..."
Twilight nodded and she used her magic and the heart in the box disappeared and was back where it belonged.
Spike up his head on Sarah's chest hearing the heart beat slowly. "Its slow but there."
"Stay with us Sarah." Apple Bloom said.
Sarah nodded and smiled as she felt her heart beat. It felt so nice to finally have it back. "I know its there I can feel it, Twilight please do the heavenly light spell please. Defeat him for me."
"But if I do that then you will..." Twilight said as a tear ran down her face.
She smiled and winced in pain. "I know..just do it."
Twilight looked at Cadence who was making a shield around the others as they all did their hardest to fight. "Cadence we must do the spell now."
Cadence nodded and they took out the spell. They stood side by side and spoke the spell aloud. "With magic all around in times of good and bad. The darkness comes and makes things sad. We speak the spell to show a great and wonderful sight, we say this spell heavens light. Away from the darkness in evil's soul we call. We are here to save before this empire fall." The light their horns glowed and covered up Sombra and he turned back into shadows. All over Equestria the black crystal pillars that Sombra's magic had caused disappeared and the feeling of despair was also gone. Outside the crystal heart glowed and spread its light all over.
Everypony went over to the Cutie Mark Crusaders, Spike and Sarah. When the two alicorns did their spell it made the purple and pink scales Sarah had to turn back to the original white color to which were first like when she was hatched. Her heart beat was very slower now and a tear fell from everypony's eyes.
Pinkie's hair went flat. She sniffled. "We are going to miss you Sarah."
Twilight looked at Sarah. "Are you sure theres nothing I can do?"
Sarah nodded. "Yes I'm sure. Im glad to see that your all are alright. This feels like it is all my fault."
Sweetie Belle shook her head and put the pink cloak on Sarah. "Its not."
Spike smiled slightly as he held Sarah. "I wish we could have met sooner.."
Sarah smiled, her necklace glowing a little brighter. "Me too..oh Spike please remember this, you are baby dragon just like me, our beginnings that we had may have been different like paths we took and walked up to today, you were hatched by somepony during an exam and I was hatched by evil out in the cold but we both are still dragons none the less so even if are different we are both still family. " A tear fell from her eyes as she closed them. "Goodbye brother.." Her heart soon stopped and white light covered her body and it made her disappear leaving only her pink cloak and her black crystal necklace but the black crystal had turned white and it soon stopped its glow.
Spike looked at the necklace. "Goodbye sister, I love you." He went over to Twilight and cried on her shoulder.
Soon everypony was crying at the lost of their friend. They all wished that it wouldn't have ended like that. After an hour Princess Celestia and Luna had arrived and saw that all the sad ponies and baby dragon were still sitting in bedroom where Sarah had left in. Twilight explained what happened in full detail from beginning to end and Celestia nodded. She looked at Spike and knelt down to him. "May I see that necklace."
Spike wiped away a tear and handed it to her slowly.
Celestia took the necklace and scanned it with her magic. "This necklace wasn't always white am I right?"
Apple Bloom nodded. "Yes. It was black, why is it white now?"
The Princess of the sun smiled. "Your friend..Sarah? Is that correct? Had purify the dark magic in this crystal with her own."
"Dragons have magic?" Fluttershy said in response to what Celestia had said.
Celestia nodded. "Yes they do. All creature big or small have a certain magic inside them. It might not be like the magic that unicorns or alicorns use but there is a magic in everypony. Your friends magic was full of good so she was able to purify the crystal. "
Spike eyes widen in surprise. "Really? My sister did that?"
Twilight smiled. "Wow.."
Princess Luna went over to the scrolls that Sarah had written on for her journals. "What are these?"
Rarity shrugged. "I don't know, they were there when we arrived."
Cadence walked over and looked at them with Luna. "They appear to be journal entries." Luna looked at one of them and passed it to her sister.
"This is one ye might want to see dear sister." Luna said.
Celestia nodded as she took the journal entry. She read it over as she gave Spike back the necklace. When she finished she looked at everypony. "Your friend seemed to have dreams about a place I have heard about and that since her body isn't here, it makes me believe that she went back to this place as if by magic."
"Where?" Rainbow dash said.
Celestia look a deep breath. "It is a place where dragons go when they die but some say that they are their before they are hatched. Legends have stated that the entrance to this place is somewhere in the frozen north passed the Crystal Empire and it is also stated that you can try to bring them back if you pass all the challenges and risks."
Spike stood up. "I want to go. I want to get back my sister. I don't care about the challenges and I'll face the risks if I need to. Please tell me where to go."
Applejack put a hoof on his should. "Your not going alone. We all will help you."
Rainbow dash nodded. "Yeah we will stick to you like glue and help you Spike."
He smiled. "Thank you, you ponies are the best."
Twilight smiled. "Then its settled, we will find her. Cadence may you either watch Apple Bloom, Sweetie Belle, and Scootaloo till we get back or make sure they get back to Ponyville."
Shining Armor nodded. "We will make sure they are well watched, don't worry Twi."
The fillies sighed. They wanted to go but they understood. They just hoped that they could get Sarah back.
Luna walked over to her sister. She looked at the group. "Thy journey will be hard we wish ye luck."
Spike nodded. "We will need it. " He folded up Sarah's cloak and put on the now white crystal necklace. When he put it on, he felt as if Sarah was right next to him.
"Yeah we will." Pinkie pie said her hair had just poofed back up.
Cadence smiled. "You all should get some sleep. We will get everything ready in the morning and you can start your quest."
Celestia nodded. "Yes get some rest my little ponies. It is now late and you all have had a very hard day. The next few might be harder. "
They all nodded and went to the other spare bedrooms in the castle. Even the Princesses stayed so that in the morning they could give more info to them before they go off on their journey. Only Spike and Twilight stayed in Sarah's bedroom. Twilight looked at her baby dragon friend. "We will get her back. She is family after all."
Spike nodded and clutched the crystal in his claw. "Yes family. She is my sister and I will do anything to get her back." Twilight put out the light and everypony in the castle was asleep.
