AN: It's finally here! the squeal to my story Chosen. I suggest reading that first to full understand what's going on. Enjoy the story!

Prologue:

"This is where you'll be going for you're first mission," Purity a glowing white hedgehog with long hair in a silver dress said, gesturing to the image in the pool. "It's going to be a simple simple mission to help you get used to your new role. There's a prophesy involving these three that's about to come to fruition where they'll finally be able to defeat the evil of their world."

"I'm guessing it's not a rush in, beat the bad guy up and leave type of deal," Sonic commented, looking at the pool.

"Very true," Purity replied, letting the image fade. "You can no longer take the direct route, at least not initially, otherwise you rob the inhabits of their heroic destinies. No, you'll be a support and a partner. And if there is something there that shouldn't be there, that's when you'll have a more active role. In this case, you'll be a silent protector of these three until they can fulfill their roles."

"There has to be something more to it, you wouldn't send me there unless it's possible that they would seriously need my help. So what is it?"

"You're right. One of the chaos emeralds of their world was broken once and the energy was unleashed. While they were able to neutralize it, I'm concerned that there might be some unforeseen side effects."

"It broke? How could one of those things possibly break!?"

"The energy of that world is very fragile because of all the damage that their Robotnik has done and is doing. And since the emeralds are tied to the worlds they reside on, both to contain their energy and to benefit the world, they were equally as fragile."

"Okay, I think I got it. Watch over and protect those three and keep an eye out for any out of control chaos energy. When do I leave?"

"As soon as possible, but I need you to know a few things first," Purity replied, getting up from the pool side and going to a cabinet that appeared. She pulled out a black cloak and handed it over to Sonic. Sonic put it on and let out a low whistle. It fit around him perfectly and was very comfortable.

"This will keep your identity hidden," Purity explained. "Not only will it disguise you, but it suppresses your energy so only those that are energy sensitive will notice anything different about you. But the more powerful you get, the less it'll be able to hide. But by then you'll learn to suppress your aura manually."

"Wait more powerful? I'm joined with the chaos emeralds, how can I get more powerful?"

"While you are joined with the emeralds, you have yet to unlock your powers. You'll be able to manipulate the chaos energy in ways you haven't before. You'll have both old and new super forms. And you'll be able to connect with the energies of the universe to guide you in protecting the multiverse. But it will take time for you control all your powers, so you can slowly adjust to them and remain in control."

"Great, just what I need. Lots of power that I don't know how to use yet," Sonic grumbled with a roll of his eyes. "I guess I know why I get something easy for my first time. Well let's get going."

Purity nodded and held out her hands over the pool. A white glowing rectangle appeared, almost like a doorway. Sonic couldn't help but whistle again.

"This will lead you to to that world," Purity said, lowering her hands.

"Neat trick," Sonic replied walking up to it. "You'll have to teach me to do that sometime."

"Don't worry I will," Purity said with a small smile. "I will still be able to contact you in that world, but I cannot directly help you or interfere."

"I know," Sonic replied. "That's my job to get things done."

Turning to the portal, Sonic jumped through. He landed in a small forest and the portal closed behind him. Looking around to make sure no one had seen him, Sonic pulled his hood up, covering his face in shadows so only his eyes were seen.

Purity, you there? Sonic called in his mind.

I'm here Sonic. Purity replied. And you need to go north from here. Those you seek will be traveling by in a van in that direction in a few minutes. You'll easily be able to follow it.

Right. Sonic agreed, pulling his cloak tighter around him. He speed off through the trees, interested to see what this version of himself would be like.

AN: Can anyone guess where Sonic went? :)
