That will probably be a decision between me and Christina Stiles, the author - it could very well be anywhere from 16th to 19th century. Although Masque of the Red Death rules could be applied as well, which fit a 16th century world. Really the goal is to keep this using Pathfinder, with our own rules extension in the publication. Christina Stiles first published adventure was for Masque of the Red Death, Ravenloft. My goal is to keep it in the era of black powder pistols and muskets (which fits early 19th century). I think 19th century is too late a period in my thinking, but it is not out of the question.

Jane Eyre and Pride and Prejudice, to me fits 18th century well enough, and this is the inspiration.
