   Summary

   Shadow the Hedgehog is 1000 years old and is still haunted by the memory of Sonic the Hedgehog. Mainly in the form of how he is used in the religion, Chaostisism. Shadow in his advanced age is more through with life than ever before, but life isn’t done with him.

   Silver is on old man babysitting duty. Shadow doesn’t know the value of his own soul, but that’s information for Silver to know and Shadow to find out.

   The new hero, Ze is about to get caught up in these two’s shenanigans and have his whole world view rocked.
