Keziah Mason
Salem Witch & Walker of Angled Space
A seventeenth-century witch who escaped the gallows by walking through walls, whose curved lines and Black Book survived in secret, and whose spirit tormented Walter Gilman from beyond ordinary death.
Overview
Keziah Mason is proof that the Salem trials documented only a fraction of what walked New England. Accused in 1692, she told Judge Hawthorne that she could walk through walls using lines and angles not taught in churches - and she demonstrated enough truth to terrify the court before vanishing from her cell.
Her legacy is not a grave but a geometry: curves that open where no door exists, a familiar named Brown Jenkin, and a Black Book passed hand to hand until it reached a student in the Witch House.
Description
Survivors describe Mason in dreams as alternately ancient hag and leering young woman, always accompanied by the sound of small hooves and human laughter. Brown Jenkin - part rat, part miniature man - runs her errands between worlds.
Her knowledge aligns with Yog-Sothoth, the Lurker at the Threshold, though whether she served or merely exploited that power remains disputed among Miskatonic occultists.
Historical Record
Trial transcripts and Gilman's account form the core evidence. The Witch House itself is catalogued under Arkham locations; architectural surveys confirm abnormal corner angles on upper floors.
No remains have been recovered. Assume active spiritual presence during Walpurgis and solstice windows.
Archive Notes
Cross-reference Walter Gilman and forbidden knowledge concept files. Personnel researching non-Euclidean architecture must not lodge at the Witch House without Protocol Sigma clearance.
