I found a straight up sith system. The system has 3 planets, all lifeless. The atmosphere is dark red with black land. There were some intense looking warships hovering above the planets that looked different than trade freighters. The sentinels are extremely aggressive and would attack me on site, even if I did nothing. I'm tempted to go back and see what there protecting cause there was no life on any of these planets just aggressive sentinels and hostile atmospheres.
