This extensive text contains excerpts from the horror novel Black Cathedral by L. H. Maynard and M. P. N. Sims, detailing a paranormal investigation team's terrifying encounters. The narrative primarily follows Robert Carter, a psychic investigator, and his colleague Jane Talbot as they travel to a desolate Scottish island, Kulsay, to investigate a series of strange disappearances, which include missing corporate employees and Carter's previous assistant, Sian Davies. The team battles supernatural manifestations, including a man sinking into a patio and walls infested with flying beetles, eventually uncovering a dark history involving a centuries-old Marrano named deMarco who twisted Kabbalah to achieve a form of immortality and build an army of the dead beneath an old church. The excerpt concludes with the team confronting deMarco in his underground "cathedral", where he reveals his intent to use his recruited army against his old enemies, the Catholic Church.
