What's next? I'm going to go ahead and add every hex that popped up as having a system on it to the list. More specifically, I'll make a second list below that one that has all of those. I will use this just for reference; I don't actually intend on going on a massive data sheet creation bender. In fact, I don't have any plans for the moment to even do a single additional data sheet, although I'm sure that I will eventually do so. Mostly, it's just to "claim" the hexes, show the political affiliation, and if I've come up with a name for the system (I did add a fair number of names already) I'll note that too. Then, as I'm working on AD ASTRA stuff in the future and need more detail, I can just pull from this well and whip up a new system. I've got names for many of the other colony areas, as well as Outremer, and it is my intention to eventually get around to that. All of the Altairan Ascendancy, both North and South, is named, although I haven't done squat-all with it other than name the systems (apologies to Tarkin.) I even named half of the Reaver worlds. This will be helpful if I just need to refer to another world obliquely to create the illusion of depth, without having any details about it yet.
I've actually done the same thing with history. I refer to a few things, without explaining them. I actually don't have any intention of explaining them. If you recall, in the first Star Wars film, Ben Kenobi refers to the Clone Wars, but doesn't explain anything about them other than that he was a general and Jedi knight, as was Luke's (at this point, unnamed) father. When I was a kid, what my imagination filled in based on that reference was probably cooler than the reality of the Clone Wars as they were later detailed. Or, at the very least, the possibilities were, which remained undetermined.
I've got a few things like this, which I want to catalog just so I can keep them straight and not forget that I mentioned them, but I don't really want to do any detailing about them other than that. Filling in detail about the past is usually counter-productive in fantasy, and this is absolutely space fantasy more than it is sci-fi as the smug, Asimovian types would call it. Besides, it's equally true in sci-fi anyway.
So, without further ado, here's a very brief history of the past.
