What if Michael is Scathach's Master
All the ghosts in Roanoke are attached to Scathach and the magic she has from the "older gods." What if the existence of all ghosts can be attributed to these older gods? Michael the antichrist was born from a union of ghost and human, maybe that's the way for one of these gods to enter our world. We could have Michael and Scathach vs the coven
