Something like this...

Note the time it took me, less than 45 minutes!
That includes...
- Randomize all in a Map editing session. Putting in a custom system & its neighboring two "fake blues". (Which were Purple on the original file, some glitch from Twilight possibly!) All within parameters enforced by the engine; example.... Same sector for any system & its planets, 5 maximum, etc.
- Give a few systems to temporary races while not forgetting Florin to Custom Race.
- Firing up Twilight, making a few scouts to light up the fog.
- Snapping the shot, uploading to ImageShack.
The only remaining work to allow for this kinda stuff would be to change the "intruding Blue Stars" textures by creating a fake temporary blackened texture for the default file (found in the DL folder), integrating it into a MOD location, activate it & starting a game with your new map.
