Actually, the whole chapter was really long (To me), so I had to make it cut it into Chapter Five and Six. The rest of the story will be next in Chapter Six. Anyways, enjoy.=D

Chapter Five

ThunderVolt

The Shadow

Thunder felt his heart sink, they're looking for me. He looked around, he saw downstairs that nopony was there. Thunder swooped down to the floor, and looked at the first floor, nobody was there also.

He sneaked downstairs and exit the library, there was no one out in front. He flew and hid in the library's leaves, flying softly to the leave' branches. He sighed, they'll never find me, he thought.

Then, he heard a familiar voice, he pushed his face out of the branches, and saw Rainbow Dash talking to the guards. "I told you, I didn't see my brother, "She said annoyed. "Miss Rainbow Dash, please give us information about him?" The guard said with no emotion.

"Why would I tell you? "She said suspicious. "Stop mocking us! "The guard angrily said, making Rainbow jump. "We would not like you to whine, or face the consequences! "The other guard said growling, "Now tell us where your brother is!" Twilight stepped in, "Rainbow doesn't know." The guard chuckled, "I know she is lying!" The guard pushed Twilight aside and shouted, "Tell us!"

Rainbow didn't look scared, just annoyed. "Again, why would I tell you?" She asked. The two guards growled, until their fur looked surprised and stepped back. The guards' fur turned black, and the armor turned silver with red. Their eyes staring daggers at her as they growled, Rainbow seeing darkness in their eyes.

Their manes and tails black and gray. The first guard now held Rainbow's neck, making her hover off the ground. She choked and gagged. "Now tell us mare, or we will make you tell us the hard way!" The guard growled in a menacing voice, horrible than any other.

"Rainbow!" Twilight and a nearby pony yelled. Applejack ran at the guard, to end up flying at a wall. "No pony can protect you Thunder, come out!" The guard growled.

Thunder felt a tear streaming on his fur, he could not let Rainbow hurt, he can't. He felt complete rage, they won't hurt her, I have to do it. Thunder felt strong, and flew out of the bushes, and landed in front of the two guards. "You want me?" he asked.

The guards smiled,"Finally, we were looking in all of Equestria for you, the princess will put you back into your cell. "Thunder noticed that their coats were turning back into their original color.

They put chains on his hooves, and made him follow into a barred chariot. They locked him in the prison chariot, and put on the cart's restraints, and they flew off. Thunder felt a tear. I'm still loyal, to protect you, Thunder thought as he was riding the chariot. He felt a cold needle stick into his body, and he fell unconscious.

Twilight Sparkle

Twilight had millions of questions in her head. Why were the guards looking for ThunderVolt? Why did the guard's white fur turn into black? Did everypony held a secret from her? She felt mad and helped Applejack up. "Thanks Twilight, that was a doozie," she said. Applejack saw Twilight's expression, "What's wrong Twi?"

"You lied to me, "Twilight said, "When something urgent happened. You had to lie, was everypony was against me? You were the Element of Honesty for goodness sake!"

Applejack fidgeted with her hooves, "I didn't mean to hide anything from you Twilight. "Twilight said, "Then why did you lie? "Twilight sweated. "I promised to Thunder, "She replied. Twilight looked at her, "What did you promise?"

"Promise not to tell ya this, "Applejack answered explained everything to Thunder's life and imprisonment."So he didn't want to tell, sorry for lying to ya, but I promised to keep it a secret, "Applejack explained."

Twilight had a shocked impression, "He just wanted to protect his family. "Applejack nodded, "He didn't do anythin' wrong, we should rescue him." Twilight opened her mouth," Are you crazy!?We're stealing from the princess, she might banish us from Equestria!"

"Yes, but he saved Rainbow. We should see Princess Celestia to make her reconsider?"Applejack said. "We could do that, alright, let's do it," Twilight said. "I will help Thunder, if you want me to?" Fluttershy said. "Yes Fluttershy, we need all the help we could get," Twilight said.

"I will like to help him," Rarity said. "We need him for the two parties, so I'm going to get him," Pinkie reminded them. Twilight face hoofed. The five stared at Rainbow,who was looking at them.

"Well, he helped me, okay. But I still don't trust him ,"Rainbow admit. "Let's do this, "Twilight said."Alright!"Everypony said, except Rainbow. "I don't think you could go anywhere?" a voice spoke. "Who said that?" Twilight said, they circled around.

"Why would you want my little chess piece to exit the game?"The voice said. "Who are you? Show yourself!? "Rainbow said in a fighting stance. "Why would I tell you where I am?" The voice said.

"Because we asked you!" Applejack said. "Anyway, why would you stop the fun of my pawn playing?"the voice asked. "Thunder's your pawn?" Twilight questioned."Wait, we're playing chess? Nopony told me!" Pinkie shouted.

"My pawn is playing this game, and if you stop it, the adventure would not continue for him," the voice explained. "What adventure?" Twilight said."Simple, where the pawn is captured, and I take over the king, known as Equestria," The voice laughed.

"Why don't you show your face for one second?!What!? Too ugly to reveal yourself?!"Rainbow asked. The voice growled and a storm cloud began to swirl. The cloud appeared as a face, and it looked evil, it looked like it was trying to escape the cloud. "There! I showed up! Now what is your next question?!"the face asked.

"What are you going to do to Thunder?"Rarity said. "I told you, make sure he's out of the way," The voice laughed, "And make sure your princess can't stop me and my army."

Twilight was shocked, she knew who they are. "We will stop you!" Twilight said. "Try?" The voice said before it disappeared. "Who was that Twilight?" Applejack asked.

"That was the leader of the shadowlings, King Snake Bite," Twilight said. "Who?" Applejack said. Twilight explained to them about her reading about the shadowlings, and how the master must return. "We have to alert Princess Celestia, hold on everypony," Twilight ordered.

They huddled together as Twilight transported them to Canterlot, she knew it was advanced to go to city to city, but she had enough stamina to teleport such a long distance.

They appeared in the hallway, and made it into the throne room. "Princess! Princess! We have a problem?" Twilight said,then they saw nopony in the room, only one pony.

It was a dark stallion, had a horn, had black, gray mane and tail, and he had sharp teeth. "I'm sorry," It sayed in a buzzing voice, "I think your princess is not in here the moment."
