Hi everyone! I apologize for the long wait! I had to study for my test, but I'm now free and will try to update faster! I'm glad you were all excited from the last chapter, because this chapter is gonna drive everyone wild! As promised, here is Part 4!

Sonic panted heavily, dodging another energy spear sent by Mephiles. He had to be careful not to stay at one spot for too long or he could easily get him through his own shade. Luckily, he wasn't alone since his friends are with him, but dealing with Eggman's Badniks. Surprisingly, Blaze & Silver appeared not too long ago to assist them with the fight, and while Blaze is helping the others fight Dr. Eggman and his badnik robots, Silver & Shadow are helping Sonic fight Mephiles.

"Answer me again! How did you return!?" Shadow demanded, glaring at his foe.

Mephiles tilted his head, staring at Shadow with an odd expression. "Have you forgotten what I told you earlier? I came back thanks to my savior."

"That's not a good answer!" Shadow launched a chaos spear at him.

"How uncouth of you," Mephiles dodged his attack. "You're still denying my resurrection?" He then avoided getting something thrown at him. "I am pleased you have not forgotten me, Silver."

Silver glared at him. "What are you up to this time, Mephiles!?"

"To see if he is faring well," Mephiles turned to look at Sonic. "How does it feel living without a voice?"

Sonic launched a spin dash at him, but Mephiles was able to dodge it. He used his super speed to launch multiple spin attacks at Mephiles, getting lucky to land some hits on him. However, he had to be careful of the dark tendrils and clones Mephiles left out, hoping to prevent Sonic from getting close to him. Sadly, for Mephiles, it isn't gonna happen since Sonic wants to kick his butt.

"At least your skills are far more superior than that sister of yours," Mephiles taunted.

This earned him a huge deck to his face, courtesy of Sonic who was trying not to let his anger overwhelm him. He could feel Shadow and Silver's questioning gaze on him, but he didn't care. All he could think about is defeating Mephiles once and for all before he blabs more about Sonic's secret past.

His emerald eyes spotted a dark portal opening up near where Mephiles landed, and out came a familiar gray hedgehog whom Sonic encountered. Soon, more of his puppets appeared to surround Sonic, Silver, and Shadow, in which all 3 of them are on the ground behind Sonic as he chose to glare at Zen.

Then, Dr. Eggman flew over in his egg mobile to where Zen is. "How astounding! What the letter said about you is true!"

Zen rolled his eyes. "I still don't understand why master admires your work."

"I feel honored that your master appreciates my intelligence and evil schemes to take over the world," Dr. Eggman laughed in an evil tone. Once he finished, he looked back at Zen. "But I was never told on who this master is or what this person looks like."

"He will appear in due time," Zen's icy orbs flickered over to where Sonic's emerald orbs are, then brought his hand out. "Sonic the Hedgehog, my master wishes to meet you. Surrender peacefully, and no harm shall come to your friends."

"He's not going anywhere with you," Shadow took a step forward, glaring at Zen.

Mephiles slowly stood up, then dusted himself off as if he was never injured. "Is it now time to capture the blue hedgehog?"

"If you need assistance, I'd be glad to help!" Dr. Eggman devilishly grinned.

Zen held both his hands out, as he moved them to mimic the movements of his puppets. "Mephiles. Dr. Eggman. You two stop Silver the Hedgehog & Shadow the Hedgehog from interfering. The son of Queen Aleena is mine to fight with."

Before Dr. Eggman could open his mouth, Zen was already rushing towards Sonic, moving as his body is covered in a foggy mist. Sonic dashed towards Zen, itching to have another battle with him. In the meantime, Mephiles had started battling Silver, while Shadow is busy battling Dr. Eggman. Tails and the others were still occupied with the Badniks, while also making sure there is no harm to the city and its people.

Sonic knocked out each and every puppet Zen sent after him, careful to avoid the weapons he made those puppets have to subdue him. Unfortunately for Zen, it's impossible to capture the world's fastest blue hedgehog. Even Eggman can never capture and defeat Sonic no matter how many times he tried. It's just not possible.

"Son of Queen Aleena, why won't you surrender? Don't you desire to reunite with your sister and brother?" Zen questioned, tilting his head in an almost innocent expression.

He then disappeared in a foggy mist, hiding in the ground to avoid getting hit by a gloved fist. Then, Zen appeared at another location, tutting in annoyance. "I did not ask you to join the fight, great grandson of Athair."

Knuckles froze, then snarled viciously as his face morphed into rage. "HOW DO YOU KNOW THAT NAME!?"

"He entrusted you to never leave the Floating Island in order to protect the Chaos Emeralds," Zen started to explain, smirking as he avoided every attack from both Sonic and Knuckles. "It's a shame he and your dinosaur Chomps are now my master's prisoners."

"WHAT THE HELL DID YOU JUST SAY!?" Knuckles roared at him. "YOU'RE GONNA PAY FOR WHAT YOU DID!"

Knuckles used his strength to destroy all of the puppets who try to attack him. Sonic was busy trying to get close to Zen, but had trouble due to Zen disappearing in a foggy mist and reappearing somewhere else. It's almost like Shadow's chaos control, but with no chaos emerald involved.

After a game of cat and mouse, Zen started to sigh. "How boring. It's time we end this once and for all."

Using his fingers, more black strings appeared from his gloves as they grew longer and started heading towards Sonic and Knuckles. They dodged them, but didn't see more appear from behind until they were both tied up tightly, rendering them unable to move as they fell to the ground. Knuckles struggled to get out of the thread's grip, but his super strength wouldn't help him. Even Sonic can't get out and is unable to use his speed since his legs were also tied up.

Zen appeared near them, crouching down as he scooped up a struggling Sonic in his arms and stood back up. "I believe Master Stone is waiting for us, Sonic the Hedgehog." He then stomped his shoe against the ground, as a shield appeared around them to stop an attack. "Do not fret. You shall reunite with your brother and sister after the meeting."

"So you did captured Sonia and Manic!" Knuckles shouted in anger. "What did you do to them!? And how do you know so much about us!?"

Zen glanced at him with a disinterested expression. "Calm yourself, red echidna. The Chaos Emeralds are not needed yet."

"You didn't answer my question, you creepy bastard!"

Ignoring his rants, a dark portal appeared near Zen, as he started walking towards it while holding a tied-up Sonic in his arms. Sonic struggled to get out of the dark thread, but the material felt tight and the more he struggled, the tighter it gets, and he could feel it cutting his skin. He heard his name being cried out, but before he could see who was calling for him, his vision turned dark.

When he opened his eyes, he saw that he was in some sort of glass chamber, and he was somehow floating. But what's most surprising is that he wasn't alone. There were two other chambers standing on either side of him, and they both contained a fuchsia hedgehog and light green hedgehog.

Sonic pounded on the glass, hoping to get their attention. Unfortunately, they both had their eyes closed, as if they were sleeping as they hovered in their chambers. Since he can't yell due to not having his voice back, Sonic tried to break out of the chamber, but couldn't since the chamber wouldn't break.

"I'm afraid it's been designed to be indestructible. You cannot get out of there, Sonic the Hedgehog."

He froze, then looked over to see someone standing outside the chamber, looking straight at him from the distance. Now that Sonic got a good look at his surroundings, he appeared to be in some sort of lab, but he didn't pay close attention as he looked at the person who spoke to him.

The person is a tall human male with light brown skin, short cut black hair, dark facial hair, and black sunglasses to cover his eyes. His outfit consisted of a purple blazer with a red collared sweater underneath it, purple tie, black cuffs, black gloves, black pants, and black shoes with red straps on them.

Positioned with both his hands behind his back, the human male grinned at him. "A pleasure to meet you, Sonic the Hedgehog, son of Queen Aleena and brother to Princess Sonia and Prince Manic." He gave him a polite bow. "It is an honor to make your acquaintance."

Sonic arched his eyebrow, but narrowed his eyes as he placed both hands on the glass chamber as he looked at the human with a suspicious look. Why does he look like he could be another evil villain? Plus, his outfit does kinda look similar to Eggman's.

"You must have questions on why I had you brought here," the human stated, holding one finger up. "It's very simple. You and your siblings are the keys in saving our world." He then placed his hand down. "Your sacrifices will save many lives."

He took a few steps closer, then stopped in front of Sonic's chamber as he tilted his head up to gaze at him. "I cannot tell you the full story until your siblings have awakened. For now, get some rest and we'll discuss more tomorrow morning." He then gave him a small smile. "And also, you may call me Agent Stone."

"What do you mean you know about Sonic's past!?" Shadow snarled.

Knuckles growled at him. "I'm not allowed to discuss about it unless he's okay with it!"

"Then tell us right now! What did Zen meant by son of Queen Aleena!?"

"H-Hold on!" Amy raised both her hands up to calm them both down. "Let's all take a deep breath and calm down before we do anything hasty!"

"Miss Rose is correct," Blaze said. "Arguing isn't going to help us find Sonic."

"Then someone tell this echidna to speak the truth!" Shadow hissed.

"I can't break my promise to Sonic!" Knuckles argued.

"Please, Knuckles!" Tails pleaded, eyes filled with desperation. "If there's anything that can help us find Sonic, then you gotta tell us! I'm begging you!"

"The kid is right, Knuckie. Any information you have can help us," Rouge added.

Knuckles wanted to argue, but couldn't look away from the desperate look Tails is giving him. Even the others were pleading with him. Sighing to himself, he looked at them with a somber expression. "Remember, what I tell you cannot leave this room. We don't want Eggman or any bad guy knowing about this!"

Nodding their heads to show they understand, Knuckles sat down on a chair as he folded his arms. "It all began at Mobius, where Sonic and I came from."

"The reason I ordered them to steal your voices is to test you 3 out," Agent Stone said, as he wiped his mouth with a napkin while seated at his chair. "Besides your skills, you 3 were able to successfully summon your instruments from those medallions. It is a good thing I found them before they were lost forever."

Zen dabbed his mouth. "Our mission to find them was a success. Thankfully, you 3 were not too difficult to find."

Sonic ignored him, as he was too busy focused on his siblings. He, Sonia, and Manic are seated at a fancy dining room, and on the table is a spread filled with delicious food. However, they were tied to the chair by the black threads, and the only way they could eat are the puppets feeding them bite sized portions.

He's glad that his siblings are okay, but angry that their voices were also stolen. Though he still can't figure out how they knew about them, and what they really want from them. And not only that, how does Agent Stone know so much about their past? Especially their mother Queen Aleena?

Mephiles, who fed his small clone a piece of meat, turned his head to gaze at Sonic. "As for how our saviors revived Infinite and me, we chose not to say."

Infinite agreed, wiping his mouth as the rest of the Jackal Squad ate their food. "While you 3 will help keep our world safe through sacrifice, we shall get our revenge on those who wronged us."

"Patience, my dear jackal," Agent Stone said. "Your vengeance will start once the ritual is completed."

"You mean when the lunar eclipse appears?" Zen asked. "It will come in a few days."

"Do not worry, my son. I am almost done with the preparations," Agent Stone took a sip of his drink, then looked at the siblings. "Team Underground, you 3 will help me awaken Verity, the Goddess of Justice."

Sonic wasn't sure where he is right now, but he knew he's trapped in his dream. Every time when he's knocked out or asleep, he ends up in some sort of grassy terrain filled with white flowers. They were just like the one's he had seen before when he and Helen went to the island to see them. And since its already nighttime with the full moon out, it made the flowers glow brightly, as sparkles appeared around them.

"Why do I keep appearing here?" Sonic whispered to himself, glad he can speak in his dreams. "What does it all mean?"

As he bent down and picked up the white flower, recognizing it as a white star or spring starflower, he moved it close to his nose and sniffed it. "Even the sweet fragrance remains the same."

Out of the corner of his eye, he noticed something dark flash by him. When he turned his head, he was surprised to see who it is. "Shadow? Is that you?"

Sonic took a step forward, reaching his hand out to him. "What are you doing here? And how did you get here?"

Shadow turned around, making Sonic freeze as he saw tears streaming down his cheeks. Sonic wanted to ask why he's crying, but his rival beat him to it. "I'm sorry…"

"H-Huh? Sorry for what?"

Shadow smiled sadly, as more tears escaped from his eyes. "If only I was fast enough to save you…"

"What do you mean? You're not making any sense, Shadow."

Sonic then gasped when Shadow suddenly dashed forward and embraced him, hugging him tightly as he felt his rival bury his face onto his shoulder. Feeling him shake, Sonic slowly wrapped his arms around him, patting his back in a comforting manner. "No need to cry, Shadow. I'm okay."

"I couldn't save you…"

"Shadow-

"They took you from me…"

"But I'm here-

"Don't leave me, Sonic…"

"I'm not-

"I need you…"

"Really? Well, I-

"You are my sun and star…"

"That's really nice of you-

"If you die, my heart can no longer take it…"

"I'm not gonna-

"I love you"

When he pulled back in arms-length, Sonic's eyes widened in astonishment. In front of him was no longer Shadow, but someone else. Instead, it was a female dark grey hedgehog with long hair reaching her waist, two strands of hair framing her face with a long strand in the middle reaching past her chin, a white spring starflower pinned to the side of her hair, white muzzle, silver colored eyes that shimmer brightly like jewels with star shapes in them, and around her neck tied with a black thread is a silver medallion shaped like a harp.

Her outfit consisted of a black gothic Lolita style dress with long sleeves and the hem of the dress reaching her knees. The top part of the collar is white with a white star pattern on both sides, and the bottom part of the dress had white star designs stretched around it. White stockings covered her legs, and a pair of black Mary jane style dress shoes with bows on the front, strap around the ankle, and 1 inch heel.

The girl smiled sweetly, as she cupped his cheeks with her hands covered in white satin gloves. "My sun~"

Her starry silver eyes stared into his emerald eyes, stroking his cheeks with her thumbs as Sonic's eyes began to droop, feeling his mind getting hazy as his eyes started to fade in a dull color. He felt himself pulled into another hug by her, softly purring when she stroked his quills, as he hugged her back while happily sighing.

"We are now together, my blue star."
