It is currently a little over a year since the events of Sonic the Hedgehog (360 version) that Sonic Shadow and Silver managed to save the Kingdom of Soleanna from Mephilles the dark.
Despite a series of battles and journeys following this, Shadow distanced himself from his so called friends and went off on his own. Thoughts of Maria drew heavily on his mind, and he became obsessed with the idea of bringing her back. Up to one point, he asked himself whether or not he could bring her back using the power of the Chaos Emeralds. It was a crazy and seemingly impossible idea, but it was all Shadow thought would work.
And so, he set off into the world to locate all seven chaos emeralds, which had mysteriously vanished into the world following the defeat of Mephilles. He hardly slept, he hardly ate, constantly searching for them. A great many battles and show downs left Shadow running ragged, with little regard for his own body. He finally obtained all seven..covered in bandages, feeling weary.
Removing his inhibitor rings, he seeks to harness the power of the emeralds and see what he can do..and so, that sets the stage for what is about to happen.
As stated, I hold no claim to these characters, they belong to Sega and the Sonic Team. The story that follows is a fan fiction comic of mine and Beloved Doll.
