You don't know what you did, and how you got there, or where you were, but somehow. SOMEHOW, you ended up meeting this mysterious dark hedgehog.

"I am Shadow. The Ultimate Lifeform. That is all you need to know."

"Ultimate Lifeform"? That sounded... egotistical, but you shrugged it off, not knowing any better. Shadow wasn't very interested in sparking conversation, so he didn't bother asking your name.
