Sarah cried for a few more minutes, she felt upset that Sombra took the Cutie Mark Crusaders. She knew she couldn't tell anypony about this. She thought about what might Rarity or Applejack say or do about this. Sarah figured that they would be really upset and try to do anything to find them. She wiped the rest of her tears and looked as the sun started to rise. The colors of the night sky changing to light blue with pink and orange mixed in. She sighs. "I better get back before anypony sees me."
Sarah hurried back to the library and went back to her bed, she figured she would try to at least get some sleep before anything else happens.
Spike woke up a few hours later. He was munching on a few gemstones that he forgot he had. He burped as a scroll came out of the fire. He looks at it. "Oh, Its a letter from the Princess."
Sarah turns in her bed as she started to wake up, hearing her fake brother's voice.
Twilight yawned as she came down seeing Spike with a letter in one claw and half a emerald in the other. "Is that for me Spike?"
Spike nods as he gives it to her. "Yes it is. It must be a response to your letter from last night."
Twilight nods before she reads it. "I hope so, my last letter to the Princess was about if she had any ideas to get rid of these crystals." She scans the letter, reading it carefully. She frowns and closes it.
Spike looks at her. "Anything wrong Twilight? If there is can I help."
Sarah sits up and rubs her eyes. She really wanted more sleep. "Whats going on..."
Twilight starts to pace around. "Spike, Sarah, we need to head to the Crystal Empire."
Spike eats the other half of his emerald. "The Crystal Empire? Why?"
Sarah frowned wondering why they need to head there. Her black crystal around her neck glowed but was hidden under her cloak. She heard King Sombra's voice as it came to her mind. Perfect, Sarah sighed thinking of what might happen if she went along with them.
Twilight sighs. "The Princess says we should check the Crystal Empire library for a spell that may help. Lets go get everypony."
Sarah slowly gets out of bed and stretches as Spike grabbed a ruby that he found along with the emerald he had finished eating.
"Here Sarah have some breakfast." He tosses her the ruby.
She catches the ruby and holds it to the light seeing it sparkle. "Thank you Spike." She smiles and eats it.
Twilight looks at them. "Come on you two."
The two dragons nod and follow Twilight out. One by one they started to get everypony. Rainbow dash was practicing her sonic rainbooms. Sarah smiled at the colors. She had never seen anything like it before, she wondered how Rainbow dash could do it with not much effort. Twilight explained to Rainbow dash where they were going and why. Rainbow dash replied by telling Twilight and the dragons that it will be a blast to go back to the Crystal Kingdom since it had been awhile since they all had been there.
The next pony the group found was Pinkie Pie. She was blasting her party cannon everywhere. There were streamers in the trees, confetti all over the ground and in everypony's mane, she also had given out balloons in all shapes and sizes. It seemed like that she wanted any excuse to have a party. Sarah smile grew wider as she watched the pink pony being so happy and crazy. She wondered how Pinkie was able to act as positive all the time. Then suddenly Pinkie's tail starts twitching. The group covers there heads except for Sarah who had no clue what was happening. The next thing she knew a muffin landed on her head as a grey pegasus with a blonde mane and crossed eyes was flying over them with a basket of muffins.
Pinkie pie smiles. "Oh it was just a muffin. I guess that was what my Pinkie Sense was telling me. "
Spike soon explained to Sarah all about Pinkie's Pinkie Sense while Twilight was filling Pinkie about what was happening. After that they soon got Fluttershy who was just feeding her animals. They filled her in as well and soon they were almost ready to go.
They found both Rarity and Applejack at Sweet Apple Acres which seemed strange to Sarah since she thought that Rarity hated everything that was grim and dirty in her eyes. They both looked worried. Sarah could guess why. It was cause they couldn't find their sisters. Twilight went up to them and told the of the plan to go to the Crystal Kingdom.
Applejack frowned. "I would love to Twilight but I can't find Apple Bloom anywhere at the moment and I want to know she's alright."
Rarity nods. "I can't find my sister either. I thought her and the other Cutie Mark Crusaders would be here."
Rainbow dash nods thinking. "Yeah your right. I haven't seen Scootaloo either to tell me how awesome I am."
Spike scratches his head. "That is strange."
Fluttershy nods. "Yes it is. I hope they are alright."
Sarah nods looking at the ground with a frown. She as well wanted the three fillies to be alright since it was her fault they got into this mess. She hoped King Sombra hasn't hurt them.
Twilight looks at Sarah. "Is something wrong Sarah?"
Sarah looked up at Twilight. "No I'm fine. I'm sure the Cutie Mark Crusaders will come back while we're gone."
Applejack nods. "Yeah yer right, I'll just have Big Mac keep his eye out for them."
The group nods and agreed to head to the train station after they had all their things prepared. They went their separate ways. Twilight said she was going to fly back to the library and that left Spike and Sarah walking.
Spike looked at Sarah. "I guess you know how Rarity and Apple Jack feel right now."
Sarah looked back at him wondering what he was talking about. "What do you mean."
"You know not finding you sibling. Like when you couldn't find me." Spike replied.
Sarah nods remembering that she was suppose to be his sister. "Oh yeah, I guess I do. " She gives him a hug.
Spike smiles as he continues to hug her. "We are together now and that's all that matters. AJ and Rarity will find the CMC soon I know it."
Sarah nods and stops the hug, not really believing that they would find the fillies. She expected the worst considering she knew a lot about her master and the pain he was able to cost even if he is just a shadow at the moment.
They continue to walk back to the library and saw Twilight getting her things together. She looked as if she was ready for anything and wanted to get rid of the dark crystal before all of Equestria would be covered. Spike helped Twilight with her things and they all headed to the station. When they got there the rest of the gang was ready to go with their tickets in hoof. Soon the pink train came up and they all went aboard. Sarah took a seat by the window and Spike sat next to her.
"Oh I do hope my dear Sweetie will be home by the time we get back." Rarity said.
Rainbow dash nods. "I bet they are just trying to earn their cutie marks."
Apple Jack shook her head after remembering something. "I know that Apple Bloom didn't come home last night. What in the name of Celestia made them not show up."
"Does anypony know.." Fluttershy said quietly.
The group said that they had no idea. Sarah hesitated to respond at first. "I know..." before she could finish the sentence she felt a horrible pain in her chest from her master squeezing her heart and her crystal glowed back as she heard his voice. Be careful what you say... She took a deep breath.
Twilight looked at her with a worried look. "Are you alright?"
Sarah nods taking another breath. The pain subsided in her chest, the crystal stopped glowing not like anypony could have noticed it and she spoke again, making up a lie to go with her story. "I was saying I know how you both may feel. When I was looking for Spike, I was really worried.."
"Well they will turn up soon and when we do we can celebrate. We have to hope for it but for now lets just focus on those crystals popping up." Pinkie pie replied.
The group nods and start discussing the problem. As they did that Sarah sighed and looked out the window when the train started moving. She thought back to the day she was given life and wondered if she made the right choice that day.
