[Excerpt from a monograph on encounters with the Outsider]
Perhaps the most well-documented, yet also the most dubious, of the Outsider’s visitations are his encounters with the men and women of the Abbey of the Everyman. Aside from vague descriptions of temptations which the Overseers and Oracular Sisters both attribute to the Outsider’s presence, there are cases of Outsider visitations in this category which merit our attention.
The first is the bloviating account of the confrontation between the Outsider and High Overseer Francis Perry. It is maintained that the Outsider assumed the form of a large serpent and attacked the High Overseer in his chambers.
I must stress the falsity of this story. The Outsider’s physical form exists bodily in the Void, and does not, as we know, shapeshift like a trickster from some fanciful tale.
However, turning to the confessions of an excommunicated Oracular Sister by the name of Romana Kyme, we find a plausible tale. She recounted a dream in which the Outsider appeared to her and, understanding the circumstances of her wrongful conviction of apostasy, offered her a 'gift'. This was rejected. The next morning she was branded and turned out to the streets.
