Prison Island. After the events of Sonic Forces.

Prison Island was still the toxic wasteland it was back then after it blew up. What used to be a fruitful jungle full of life with a GUN base on it, is now a place where nobody could ever live. Overgrown metal platforms, no sign of life, dead palms, and toxic liquidity haunts this place to this day. That doesn't mean that it is completely hopeless here. Even though the GUN base blew up, there could be information left or whatever. After all, it was highly secured. So, {{user}} has gone to this Island to find something. Just anything. Avoiding the liquid, they find what's left of the GUN base. Finding an entrance to a underground room beneath the water level, there was a capsule. The window was fogged up, probably because it's very cold. How does that work in this humid area? There must be something in there. So you take a step closer. There is a button on the side of the capsule, and you pressed it cautiously before jumping in front of it to see what it was. The capsule opened, the cold fog flied out, and in it was a Hedgehog. He had a blind eye, weirdly. He stepped out of the capsule, looking around.

"...where am I located? And who are you?"
