    Every result is a single short investigator brief written from the perspective of one fictional character working somewhere in or near the 1920s New England that fans of the Cthulhu Mythos will recognise. Each brief is built from a small cast of recurring ingredients: an occupation or side trade, the way a particular investigator's grip on their own nerves is fraying, the last place they were seen, the working title on their case folder, and the small private habits that mark them out as a person rather than a dossier.

    The generator pulls from twenty topical lenses including 1920s occupation, sanity pressure, last known location, case file title, antiquarian contact, forbidden book exposure, speakeasy or university scene, war trauma shadow, strange skill useful once, missing colleague link, newspaper clipping clue, family disbelieves them, cult symbol recognition, travel trunk contents, phobia or obsession, private vice, Mythos encounter restraint, notebook handwriting, final address before disappearance, and investigator name with period feel. Each lens is a separate slice of the world, so a roll from antiquarian contact reads differently from a roll from cult symbol recognition even when both involve a contact inside the case.

    Every brief begins with the same template, a single investigator and a single small anchor that holds the rest of the paragraph together. The anchor is the lens itself: a French phrase book that still smells faintly of machine oil, a single brass compass that has not pointed true north since the autumn of nineteen nineteen, an antiquarian in Vienna who signs every letter with a faded green seal. That single anchor does the work of a whole paragraph because the surrounding details are tuned to it.

    The briefs are written to feel at home next to a 1920s tabletop session handout. There is no em dash theater, no melodramatic reveal in the final clause, and no canon names borrowed from the source material. The investigator's mentor might be a blind smith who never asked their name; the mentor is never a Mythos canon figure. The forbidden folio might be a quiet smell of copper kept in a small leather book; the folio is never a verbatim citation. The voices are inspired by the period tone rather than quoting it.

    For tabletop campaigns, treat each brief as a one-line NPC sketch. The anchor becomes the first hook at the table, and the supporting detail becomes the second. A player who hears that the investigator's notebook handwriting switches, on a single page, from copperplate to a hurried upside-down scrawl has something to ask about, something to investigate, and a possible return for a later session.

    Every brief is written to be usable as a starting point for a character sketch, a session-zero handout, the opening paragraph of a short story, or the first line of an NPC entry in a private investigator's case folder. The language is deliberately period; the briefs stay in the 1920s without lapsing into melodrama or genre pastiche.
