After fighting Scourge and rescuing Rouge from Eggman, Penny was starting to like the world she was in as well.

The three of them were entering the castle of Soleanna as they discussed the history of what happened with the place, Penny was getting a bad feeling about the place but she decided to keep her guard up in case.

Shadow, Penny and Rouge walked to the middle of the castle were broken pieces were spread around and the ceiling that is fallen to show its darkness.

"The former king of Soleanna used to reside in this castle. But a major accident occurred ten years ago, and no one's lived here since." Rouge said.

"Accident?" Shadow and Penny both replied.

Rouge rolled her eyes and continued talking.

"I heard a prototype energy engine failed, which caused the accident. I think the name of the plan was..."

"The Solaris Project" interrupted Eggman.

Rouge, Penny and Shadow looked up and found Eggman hovering in the sky.

"It was an ambitious project named after their enteral sun god." Eggman looked down at Rough and Shadow, when he finished talking.

"Doctor!" Rouge sounded a little surprised that Eggman was here.

Penny was shocked to see Eggman like Shadow and Rouge had described about, she didn't like the man one bit.

"It's been a while, my dear Rouge. And of course, Shadow. Not if you'd be so kind as to hand back the Secret of Darkness you took from me." Eggman didn't want any more distractions, he had enough, he needed to get everything he plan on doing before it went haywire.

Or worse!

Eggman called for his robots and they surrounded Shadow, Penny and Rouge pointing their guns at them. One of the robots pointed their guns and shot, but was to slow.

Rouge took the sky and Shadow took the ground while Penny was about to unleash her swords at the robots surrounding them.

Eggman hit a few buttons on his machine and hit Rouge.

"Ahh..." screamed Rouge.

Penny glared at the man who shot down Rouge as she unfolded her swords and attacked his egg carrier which caused him to stumble and the scepter to slip.

It worked but the Secret of Darkness was in his hand and fell. Shadow looked up when he heard Rouge screamed and ran to her and caught her. Rouge looked at Shadow and got out of his arms.

Everyone watched the Secret of Darkness fall down.

"No...!" shouted Eggman from his ship.

The Secret of Darkness broken into pieces with purple light coming out. Then suddenly black smoke came out of the scepter and went straight up and moved around the castle destroying all robots.

Shadow, Penny and Rouge watched as the black smoke went around and heard Eggman yelling.

"It's no use! Pull back, pull back, pull back!"

Shadow, Penny and Rouge watched Eggman fly away.

Shadow, Penny and Rouge looked back at the black smoke going up into the sky, then in went down into the ground, under the surface. Shadow and Rouge walked up to where the black smoke was and just stand there observing.

Shadow saw his own shadow on the ground, and his shadow moving to the black smoke. As his shadow was gone, Shadow saw himself. Rouge was just as surprise as himself, Penny was scared at the bad aura it gave off."What?! His shadow..."

Shadow saw his shadow had green eye, with gray stripes in his hair, two rings on his wrist and feet, and white gloves and black and white shoes.

"Hah hah... Oh, how ironic fate can be! I would never have believed I would be resurrected through your shade! I thank you, Shadow The Hedgehog!" as he bowed his head to Shadow.

"Who are you? How do you know my name?" Shadow growled.

"I'm Mephiles. Mephiles the Dark." Mephiles started walking up to Shadow and Rouge with his head down and dragging his feet. "What, did you forget me?" Mephiles went on.

Shadow was even more confused, how did Mephiles know him but he didn't?

Penny knew that this guy was bad news as she backed away from him which only caused him to turn around and laugh when he saw how afraid she was.

"I owe much to you, Shadow." Mephiles was standing right in front of him, lifted his head up, to show his green snake eyes to Shadow.

Shadow ran up to Penny and Rouge, when Mephiles put up his hands. "Oh, yes. What you gave to me, I now return to you!" Mephiles brought up his hand and a purple with black lines ball, showed up in his hands and continued talking. "A one-way ticket to oblivion!"

Mephiles raised his hand over his head and the ball got bigger, big enough for Shadow, Penny, Rouge and himself to go to oblivion.

The light blinded Shadow, Penny and Rouge, they covered their eyes and tried to run away but it was too late, they disappeared.

With Mephiles to join the fun.
