Whoa. This is a really great story... One of the best I've seen!
Not to be rude or anything, but just a small note (Just another one of my useless rants):
If Kdom was the same size or larger then Solaris then their combined gravity will most likely pull themsevelves closer together. Considering the proximity of Kdom to Solaris, Kdom will be vaporised if it gets anywhere near Solaris. To support life, I assume Solaris is a medium-sized star; much like our sun. If this assumption is true, and the ratio of your star-system pictures are correct, I could safely conclude that Kdom will eventually fuse with Solaris... Increasing it's size and density. This sudden increase of size and density will greatly increase the heat, light and other radiation outputs. So if this will happen, all current life on Genesis will be destroyed. I believe that Uru, putting into consideration that they are a relatively advanced civilisation, will be able to forsee this happening and move out-system before this catastrophy happens.
Of course all this is based on real life, and the journal is based on a computer game! My useless rant was probably not correct at all, but it is your journal and you make the rules! http://www.simtropolis.com/idealbb/images/smilies/3.gif>
