Somewhere in the Void between the Worlds something or someone is collecting what remains of the broken ones, fusing the things that were meant to be broken back together into a horrific fusion of what they should have been.

While not a single person knows the answer to any of these questions, who knows if you are willing to follow the inhabitants of this merged yet broken world, you may find the answers.
