Seems pretty cool; got the chance to flip through it a little bit today.
[SPOILER - highlight to read]: Confirms that Palpatine is responsible for the Stark Hyperspace War. And that Zsinj has no first name. And that Ardus Kaine's mini-Empire became the heart of Pellaeon's holdings towards the end of the Galactic Civil War. And that the actual amount of territory held by the Separatists was substantially smaller than that held by the Republic.
