Here's the graphic:
Halfway through Book Five: Sagittaron. The first half dealt with the arrival of the imperial forces of Virgo and Leo on the planet. The second half picks up a few centuries later once the oppression has been codified and the people are becoming set in their ways (ways that persist all the way until Battlestar Galactica).
Throughout these books, I'm using the Messengers of The One True God as connective tissue, interviewing people from my books and the TV shows to set up, recap, ask questions, etc. I try to use characters attached to the colony in question, of course. There are two known characters related to Sagittaron: Anastasia Dualla and Tom Zarek. I've used them both. In fact, you can read Zarek's chapter after the JUMP.
