I spent a lot of time in the early months of this project mapping out the historic time lines and building the Sibylline storyline through many, many (did I say many) versions of story maps like this one.
The trilogy spans a history of more than 2,000 years and dialing in time periods, historic events and characters that made sense proved more than a little tedious.
These were an amazing way to pile everything into one place, then start moving, throwing out, adding, redefining and finally determining the story.
