In the year 2727ad, the human race has a sphere of influence almost 1000 light years in diameter. On the world locals just call 'the sea', bio engineering of native life have given rise to living floating cities where most of mankind makes its residence. With no landmass what so ever, taking to the air is the only choice. 3 suns make up this sytem (a ancient orange-red giant, a sol standard sun and a hotter one massing 2/3rds a solar mass). A forth extremely bright blue-white supergiant rogue star is slowing passing by at about 1/2 a light year. In a few million years it will be at hundreds of light years distance. Just as well, as at about that time it will have exhausted most of its fuel supply and have gone supernova, sterilizing all nearby starsystems. This one was just a experiment for me, found a tutorial on making multiple suns in bryce and gave it a shot. I liked the reflections of colour in the water so much that i decided to make a world out of it. Just made sure it didnt get cluttered with surface based life. In this case ive decided to keep it simple.
