The Missing Hedgehog

After being rescued from a suprise encounter from Eggman by a shadowy figure, Shadow the Hedgehog is curious to figure out who, or what, saved him that very night. A couple days later, people have claimed there to be a monster in the woods. And including the fact that he has noticed Sonic's strange behavior around the evening. Will he find the answers to all of his questions? Or will he be left puzzled, and left to die in the paws of the beast?
