I've read back over a few of the recaps from the old FoD and I'm wondering what the general feelings for the Sleiti are. I must admit that my ulterior motive is to get people (or Kev) excited about the Sleiti and maybe a few more of them will miraculously appear. On the other hand, its hard to know what direction they are going in when so little is known about them.
From what I can gather, the Sleiti can be described by these things in general:
1. Bio-engineered / Organic Technology
2. Overly concerned with aesthetics
3. Cruel, narcissistic, domineering, draconian (?)
4. Elitist, Imperialistic
5. Fast, lithe, lethal,
6. Bishounen / androgynous / epicene
Beyond those things, which may be debatable, I have no insight into their proposed culture. Are they the sort of race that would enslave others for the purpose of amusing, gladiatorial fights? Would they equip their own like Predators and hunt down the lesserbred (or beat on them for training like Feyd did in the recent remake of Dune)?
What sort of things are honorable and dishonorable for these people (if anything)? My guess is that they've got monstrous egos and a huge appetite for destruction and the suffering of those that cross them --- especially for the lesserbreds who actually manage to harm them and register as a threat on their radars.
Does it make more sense for their vanity to lead them to create indestructible bio-Mechsuits and "make war as personal as a punch in the nose" like the Cap Troopers of the Mobile Infantry, or for them to employ biological weapons to exterminate populations and then send in mop up? Is there even honor in battle, is it a right of passage, or is it more like aristocratic fox hunts? And what happens to the casualties or fatalities? Are they looked down upon for being wounded at the hands of lesserbreds, are they scientific test-runs, or is Natural Selection fine-tuning their ranks more yet?
I don't really expect answers to these questions from you forumites, but I guess I felt I had to put it out there so that collective opinion (or Kev's position) might flesh them out a little better.
