Isaac Colten is in hell, literally.

For Isaac, his death has provided one last opportunity to be there when Sam needs him the most. An unspeakable horror known as the Dullahan is determined to get its hands on Sam and it most assuredly will, if Isaac can't reach him in time. To get there, Isaac has to navigate the unforgiving land known as the Wastes and somehow survive the creatures that call it home. When he was alive, Isaac was a proud, hardworking, and stubborn man. In his death, he's going to need to be so much more if Sam has a prayer of escaping the Greenlights of the Dullahan.
