I've got a Suliban shuttle pilot onboard the Border Cutter Silverfin
My thoughts on the Suliban is that after the death of Silik the end of the 'temporal cold war' came to an end and the Kabal all but collapsed. Afterwards some Suliban settled on small out of the way colonies (seeing as how they ticked off a lot of species in the 22nd century), others would remain nomadic. The end of the Kabal also meant the end of the genetic engineering, so those abilities would diminish over time as each generation diluted the enhanced. The colonies would remain neutral, though some of the nomads would do whatever they wanted in order to make a living.
But then again that is just how things are in my little nook of fanficdom.
