Unexpected Denouement

From: Martha
Description: You’ve intrigued me with Angela Crowley’s phenomenon. I’ll help you find out where she was getting the information about the City’s inhabitants for her books. Bring me the sketches you’ve found, as well as some charged artifacts, so that I can ask the City about this.
Completed: A mystical fog is thickening above the sketches. It recedes and I see... a fortune-teller’s ball! From it appears the writer’s sketchbook in which she’s drawn the City of Shadows. Angela didn’t need any informants - she saw the future and predicted it in books herself!
