Weren't most of nobility killed or taken by Kas and her goons in wake of their departure. That, I also presume,also includes her detractors in possession of power. Also, considering that the player can become part of that Nobility and can possess the huge swaying power inside of it (if our title means anything) than that is already one supporter. Now, courtly politics are beyond my area of expertise, but abducting a royal had as much of an effect as hand behind it. And as we see, the remaining elves do not have as much swaying power as they once had.
