This is a complete system, organized by category so you can build full Lovecraftian horror gamebooks from scratch, or pick exactly what you need from the massive list of 544 prompts we provide.

You’ll find frameworks like:

Arkham Academic Investigations — Mysteries set within Miskatonic University. Professors who vanish, forbidden texts in sealed archives, students who hear whispers in dead languages, and academic secrets that should have stayed buried.

Miskatonic University Restricted Archives — Deep dives into the library's most dangerous collections. Cataloging errors that reveal hidden tomes, secret indexing systems, and chambers beneath the stacks where some books were never meant to be read.

Dunwich Folklore And Ritual — Rural horror in the decaying hill country. Missing elders, unfinished rites, symbols carved into stone, and the long shadow of the Whateley family.

Innsmouth Coastal Dread — Seaside terror where the ocean hides more than fish. Strange bloodlines, the Esoteric Order of Dagon, and towns where outsiders are noticed immediately—and remembered too long.

Kingsport Dream Mysteries — Dreamlike investigations in the misty, ancient seaport. Reality bends, time slips, and the line between waking and nightmare dissolves.

Providence Urban Horror — City-based cosmic dread. Crumbling neighborhoods, forgotten cemeteries, and secrets hidden in plain sight among the living.

Antarctic Expedition Horrors — Isolated terror at the bottom of the world. Lost expeditions, recovered journals, and things frozen in the ice that were never meant to thaw.

Cult Infiltration Scenarios — Go undercover among true believers. Gain their trust, learn their rituals, and discover what they're actually summoning—before it's too late

Forbidden Text Discoveries — Stories centered on dangerous manuscripts. The Necronomicon, the Pnakotic Manuscripts, the Book of Eibon—and the price of reading them.

Asylum And Sanatorium Investigations — Horrors behind locked doors. Patient records that don't add up, doctors with hidden agendas, and inmates who know truths no one believes.

Ancestral Curse Storylines — Family legacies that cannot be escaped. Bloodlines tainted by ancient pacts, inherited knowledge that activates unbidden, and the sins of ancestors demanding payment

Deep One Encounters — Face the creatures from beneath the waves. Hybrid bloodlines, underwater cities, and the terrible bargains made generations ago.

Elder Thing Archaeology — Unearth what should stay buried. Pre-human civilizations, artifacts that defy explanation, and the realization that humanity is not the first—or the most important.

Mi-Go Scientific Horror — Extraterrestrial terror disguised as science. Brain cylinders, remote Vermont hills, and visitors from Yuggoth who want something far worse than invasion.

Nyarlathotep Manifestation Tales — The Crawling Chaos in human form. A thousand masks, a thousand manipulations, and the creeping suspicion that someone has been guiding events all along.

Yog-Sothoth Gateway Stories — The key and the gate. Rituals that open doors between dimensions, bloodlines bred for a purpose, and the horror of what waits on the other side.

Cthulhu Cult Encounters — The big one. Oceanic dread, the sunken city of R'lyeh, dreams that aren't dreams, and the inevitable return of something that never truly slept.
