In the late seventeen-hundreds, occultist, Jospeh Crowell, was visited by an entity. The spirit revealed to him esoteric information and events that transpired in a portion of land in Michigan, before it became a state. Crowell documented that information in what is called the Ravensgate Chronicles, as the town of Ravensgate was later founded on that land. There is a connection between this document, the disappearance of Sandra Breyer, and the Unholy Awakening.
