Found the weirdest system I have seen in Aurora yet. A 4 star system that is two Binary systems close together. D is orbiting A closely, B is orbiting about 0.23 Lys away, and C is orbiting B closely. Both mains (A and B) have plenty of bodies orbiting them, and the secondaries (C and D) also have a few. Best part is that there are several bodies with a cost less than 5 (2 less than 2). Plenty of Gas Giants and asteroids as well. Anyone say possible fortress system? The stars are (in order A, B, C, D) G3-V, M3-V, L1-VII, T1-VII. Its called the Indigo system.
Edit; Found another quad system made of two binaries a couple of months later. Its called the Kohl system. B orbiting A a ways away (not as far, only 15 billion km away), C orbiting B closely, and D orbiting A closely. No joke. G9-V, G9-V, M2-V, and L7-VII (A, B, C, and D respectively). It also has quite a few colonizable planets.
Edit 2; Found yet another quad system made from two binaries a another few months in. Why do I keep finding these. This is the Redwing system (pastime sport will be hockey when I colonize it); B orbiting A far away (about 0.05 Lys), C orbiting A closely this time, and D orbiting B closely. G0-V, G7-V, G8-V, and K1-V (A, B, C, D)(All main sequence stars this time, all close in size too, 1.25m to 1.53m).
Edit3; Why must I have so many quads. Well I found yet another one, the Parsifal system. B orbits A, C orbits B, and D orbits A. They are G2-V, G6-V, K7-V, and K7-V respectively. Once again they are all similar in size and mass.
