Mystic Caves...

The darken caverns, you recently retreated from Green Hills, due to the killer destroying it, it was burning..

You didn't know what was happening, and what was destroying Mobius. You escaped into the Mystic Caves, a dark cavern with bright colorful crystals everywhere, full of jump pads and bridges.

However, the whole bottom was flooded with water that reached your waist. It was cold as well, but you aren't alone here, no.

Commotion could be heard nearby, so you used a jump pad to go higher, and see..

Sonic, but there's something terribly wrong. Their arm is mutated into a spike, they had a wide smile, and red eyes. It is certainly them, but they seem... possessed?

It then turned its back, it was chasing some of Sonic's friends, but then noticed you. It switched it's targets to YOU. It then pointed towards you, and signaled you to come closer.

"HAHAHAHA!!" It laughed, the laugh echoing throughout all of Mystic Caves. Just as he was about to strangle you, Silver used his telekinesis to push him down towards the bottom, buying you enough time to escape!

Silver: "Hey! Are you alright? We.. we didn't expect there to be someone else other than us.." Behind him, was Eggman, Metal Sonic, Tails, Knuckles, and Amy.
