De Vermis Mysteriis

De Vermis Mysteriis is a forbidden work of elder lore by Ludvig Prinn that Nathaniel Wingate Peaslee’s secondary personality studied minutely. The book matters not only as a source of occult knowledge but as one of the marked volumes through which Peaslee confronted the possibility that his altered state had left a material record beyond his conscious memory.

Place Among the Forbidden Books

During the years of his odd mutation, Peaslee’s reading drew notice: he consulted rare occult works in libraries, where his activity could not remain secret. De Vermis Mysteriis was among the books he examined closely, alongside Cultes des Goules, Unaussprechlichen Kulten, Book of Eibon, and Necronomicon. Rumours also linked him with occultist leaders and scholars suspected of connections to abhorrent elder-world groups. Those rumours were never proved at the time, though the tenor of his reading helped fuel them. An underground cult activity was also said to have risen around the period of his mutation; the account places the developments together without establishing that the book or its contents caused the activity.

The Secondary State and Its Marginalia

Years later, Peaslee investigated his amnesia and visions through systematic study of psychology and extensive consultation of medical, historical, and anthropological records. His research eventually returned him to the forbidden books that had interested his secondary personality. Some were the very copies he had consulted while altered, and they bore marginal notes and apparent corrections in scripts and idioms that seemed distinctly nonhuman to him. The marks provided tangible evidence of close study, while making the boundary between Peaslee’s remembered identity and the secondary personality harder to trust.

Evidence and Uncertainty

The account does not identify a particular annotation in De Vermis Mysteriis; the disturbing marks are described across the group of books. Peaslee found that most annotations were written in the respective languages of the volumes, which their author appeared to know with academic ease. A separate note in Unaussprechlichen Kulten consisted of unfamiliar curvilinear hieroglyphs resembling characters from Peaslee’s dreams. Librarians, drawing on earlier consultation records, told him that the annotations in the books must have been made by him in his secondary state, despite his ordinary ignorance of three of the languages involved. De Vermis Mysteriis thus belongs to a documentary puzzle rather than to a fully resolved explanation: its place in Peaslee’s reading is established, but the evidence does not isolate its own markings or clarify how his altered self acquired such knowledge.
