Game Viet Nam

So this map is for the Vega star system, setting of the Omega Men comics, as it appears in the pre-crossover-of-the-moment DC Universe.  I don't know anything about the Omega Men, but figuring out what this map means in the absence of that information would be an interesting exercise.  I think something like this map would make for a cool science-fantasy/planetary romance D&D setting.
