Cap Vaughn - My Tzenkethi in Star Trek: Lexington were alot like what you propose. I do see a Lyran/Kzinti color in yours, and as I am trying to break away from a felinoid race, I will go with a more central authority in the end. that said I like what you have put forward, if I ever do pick up Lexington again, I may just borrow your ideas
For Star Trek: Genesis since the Tzenkethi will be constantly present or at least in the forefront of alien species they will deal with, I will try another angle.
As to what that angle will be? I need a bit more time to think about it.
