It is a tad bit of a shame that this has been voted so low. On seeing the vote and the comments that pulled it down I almost didn't read it.
While sci-fi isn't a strong point for me, and there are issues with the sub which I will not go into I pulled from this what Black Jack questioned. I feel as if the Kiranti could in fact be using this station as the ulterior motive to supply the war effort with ships and false hope of alliances. There is no more profession profitable that war profiteering.
This line is what made me think this way, "offering spare capacities of their vast shipyards for the construction of warships for their friends; during all of this, they stay loyal, cute, harmless, polite."
A good, solid effort, and I will dutifully avoid the whole 'prose' issue. Instead, I'll point to my major difficulty with this. That being the whole "no context" issue. It takes me some time to get into what you are trying to talk about because I don't know that the Kiranti are a race. Likewise the Daumar don't show up for quite some time but they're somehow central to the point.
What I am trying to say is there's really no context given for how this all fits together. Lots of veiled references (like mentioning the earth that was) but no explanation for it all.
But like I said, good, solid effort and I can see a good diplomatic Bab 5 kind of campaign coming out of it.
PS though I have to say, I am REALLY curious to know if the Kiranti have some secret, long term, plan to get their enemies and allies to eliminate one another...
