OK, here's the chapter I said I would make, just in case you stil didn't completely understand, so, I hope I word this all clearly.

In the story there are three different Sonics, the young one which tries to help him, the present day Sonic that we follow in the story, and the Sonic that is seen in flashbacks and visions. The young Sonic doesn't appear much and only does so for the sole purpose of helping the present day Sonic, he could be considered the 'good' half of Sonic. The Sonic seen in the visions is who the present day Sonic was in a past life, he was blind but had a sixth sense and could see things that others couldn't, ironically. He loved Shadow, but circumstances wouldn't let them be together, they decided to house the kusabi (the repntance which could mark the end of all life on Earth etc.) as it was the only way they could be together. Before they could do this though Shadow went mad and couldn't wait for Sonic, so he killed all the people in the mansion. Sonic, now knowing that in this life he couldn't be with Shadow, hung himself, leaving behind an elixer which would give Shadow amnesia, and was re-incarnated to the present day Sonic. The Sonic we follow in the story starts visiting the manor of sleep in his dreams, no-one else could ever visit it since it is all parts of the subconcious mind, since Sonic had been there in a past life, and because of his sixth sense, he could remember it, but only in hidden parts of his mind, so he had to solve clues to help him discover of his former self. He'd had an unhhealthy obsession with finding Shadow when he fell from the ark which he couldn't explain, but later knew that it was because of the love the two of them shared, and the promise to wait always, so they could finally be together. He later looks into the abyss, which blinds him since no-one can look directly at the hell gate, so then he can house the kusabi as the white hedgehog in a prophecy. He and Shadow then go on and unleash the repentance on the world, making it into the place of darkness which only Sonic could truly understand. Through the story though, his dreams blur into reality, we leave the story in what seems to be the real world to Sonic, but his ever-lasting darkness doesn't allow him to be able to distinguise places (I may make a cliffhanger, evil grin).

Throughout the story we meet three Shadows, the 'good' one which helps Sonic, the veangeful one which went mad and killed everyone in the manor, and the neutral Shadow which finally goes on to house the kusabi with Sonic. The veangeful Shadow cannot be beaten with the camera since he is so strong, and with a single touch could either kill Sonic or force him into a vision. When the neutral Shadow houses the kusabi with Sonic, a ritual is complete which opens the gate to Hell, allowing the spirits to roam free in the world, where they will cause all life to cease to exist. Shadow is not blind like Sonic, but they're both needed for the ritual, Sonic being the darkness and Shadow being a sort of link that holds everything together.

In their former lives, people frowned upon them being together nad they knew the consequences of anyone knowing their love, when the kusabi symbol appeared on the hut wall, it gave them an oppurtunity to be together forever, even if it meant causing the repentance. Shadow went mad though and killed everyone in the mansion, they couldn't do the ritual, and Sonic knowing they wouldn't be with each other, at least in this lifetime, hung himself. Shadow used an elixir Sonic left him to forget everything, and goes to live on until the ark, where he falls to his death. Both were now in their next lives, Sonic becoming obsessed with finding Shadow for reasons he wasn;t even sure of himself until later. In the end, they house the kusabi and unleash the repentance, thus being together forever at last.

Well, I hope it all made sense, if parts don't, please tell me and I'll clarify, but, I think I might do that cliffhanger,
