There's 4 planets, and 8 Moons in this system, the is a metal rich Sub-Earth that is also about 120C, next is the 8 Jupiter mass gas giant, with 4 Moons, 2 with life, one covered in ice with no atmosphere, another rich in metals (I had to alter the orbits of the habitable Moons, because since they were so close to the parent star, it sometimes pulled the Moons away, so the 4 Moons have orbits of 2.3, 6, 10, and 18 days roughly, with the 2 outermost Moons belonging to the medieval and space faring civilization respectively) and the outermost planet is a ringless Jupiter-like gas giant with 2 ice covered Moons, and a gas dwarf 'moon' with 2 moons, one mostly made of silicate, and little in precious metals, and one rock and ice, with a thick atmosphere, there's also a metal rich Mars sized body trailing the two with a very thick atmosphere, likely a ejected moon. The parent star is a K3 main sequence star.
