I see Moose has stepped in pointing to my old thread about it. Admittedly I've been quite lazy about investigating further. I do have a series of screenshots I did one day a while back from a clear night in the Sagolii with the purpose of eventually stitching them into a pano (imperfect as it would be given the quick rate they rotate). I'll see if I can find those and upload em if anybody else wishes to try their hand at looking at my data.

In terms of the colors being more vivid at times, I'd venture to say it's game time/weather conditions affecting it.

Wouldn't call it a simple XI carryover though. The layout is quite differently, even if the similar concept of elementally aspected stars was.
