Seems the system was a dud, then. Like, we'd expected a lot with that many Galapagoans, yet it gave nothing of value. - We're still investigating the Ruined City.
Is it normal it takes that long? - No. But bigger ships do take longer.
What is it those two are? - Island is an anti-missile-missile ship. We've hardly ever engaged them, and other ships (like the Admiral) can also cover that role. General was a small-ish high-speed heavily armed ship that got totally out-performed by both the even-smaller Sabres and by the much larger Emotion.
As in civvies are doing it? Will you get to control the resulting factories? - I lent the planet some factories ands set them to building more. Civvies not involved.
Well, it's nto actually a star, but rather a brown dwarf. - I'm aware. In-game, it has zero luminosity. That can't really be true of course or it wouldn't generate a jump link.
You can see it by folloiwing the star mnemonic: Oh, be a fine girl, kiss me. Ends just before L, as it goes OBAFGKMLT, with L and T being brown dwarves. In fact, you could ven argue that M stars are more akin to brown dwarves than stars.
Anyway, should still hgave some degree of luminosity.
