Not sure exactly what they'd have to go on except a pocket cell of Kunists...but I think Sion eventually killed them all until he was the only one remaining.
Same problems over and over it would seem... To make a game based on the novel Revan seems a bit flat. It could concern itself to deal with alternate endings, or with what played out after the canonical events of the games unfolded.
For example I'd very much like to find out exactly what went down with the new Jedi Order and things (characters' fates) not covered by the novel.
We'll murder them all, amid laughter and merriment...except for the few we take home to experiment!
