ASll that's revealed is that in this game is when Lorelai says something to get Killey in prison for three years. there's a Sindar ruin in Falena, which is how you meet Lorelai (she guides you through it). And, in one of the screenshots that shows Killey, it looks as if he's in a Sindar ruin. I think Zweig (or whatever his name is..) is also a Sindar hunter. We'll probably learn a little bit more, but not much more than we already know.
