AN: UPDATES WILL BE SLOW! Mostly because the movie just came out and I don't have the ability to obsessively watch it over and over again for details I can use.
"NNNOOOO!" Sonic shouted as he passed through the fading remains of the warp ring. The lack of passing through the dimensional barrier caused him to stumble and fall forward. Sonic instinctively folded inward into a ball to protect himself from injury, rolling forward a few feet across the damp ground before coming to a stop. Sonic uncurled and pushed himself up onto his arms, his gaze snapping to the place where the warp ring had been. A few golden flacks shimmered in the air before vanishing, leaving no trance that the warp ring had ever existed except for the small hedgehog left on the wrong side.
Sonic could only stare at the empty air in shock, trying to comprehend what happened. His mind was racing faster than his feet could move, unable to wrap around how everything could have changed so much so quickly. In the span of a few seconds, he had lost his home, his island, his whole world. Longclaw, the one person who had ever cared for him, sacrificed everything to keep him safe, made sure he had been able to get away even when she knew she wouldn't. And it was all his fault.
Sonic hadn't listened to her, believing she was underestimating his abilities. He had been so confident that he could run faster than people would be able to notice that he had ignored all her warnings. That mistake had cost him everything. He had lost his home, she had been injured and might even be…
Sonic shook his head, refusing to let his thoughts go there. Longclaw was the smartest, wisest and strongest person he knew, she would be alright. She had to be… He just had to wait a minute for her to get away and come through another ring…
The rings!
Sonic jolted to his feet and raced over to where he had dropped the bag of rings. It was fine if a little muddy, and Sonic couldn't help but sigh in relief as he picked them up in his small hands. Sonic hugged them close, taking comfort in the lingering scent of his caretaker. He couldn't lose these rings, not when they were the last thing Longclaw had given him. She had told him that they were going to be his most important possessions and he would never take her instructions for granted again.
The sound of rustling leaves snapped Sonic out of his thoughts as he was reminded that he was in a strange new world full of unknown dangers. His green eyes scanned the nearby trees and even though he didn't see anything, Sonic decided it was best to move on.
Sonic carefully slipped the strap of the bag over his head and made sure it was secure on his shoulder. It was so tempting to use one of the rings to go back to his home and make sure Longclaw was alright, but he couldn't, not after what she went through to get him here. Taking a deep breath to help steady his nerves and bury the grief that was threatening to overcome him, Sonic ran off into the trees, determined to explore and learn about this new world.
