Shades

Heaven and Hell are two points in time and space that should never have touched. So are the Winchesters and the Shades. Parallel universes aren’t something to be messed with. One wrong move and the whole of time and space implodes. The earth wasn’t ready for the angels, the Doctor, the ghost hunters and Sherlock Holmes all at once. But it needed them. Some called it the Apocalypse. Some called it Silence and the End of All Things.
