I must have missed a chapter. She doesn't seem to dislike Nikephoros, who seems to be doing the same thing.
But that is because she has no reason to dislike or fear Nik, who cannot father any children and therefore might possibly, if our dowager empress plays the game well enough, name one of them as his succesor. Manuel, as a technical bastard, is threatened by Sybyslava's children as he, after declaring himself emperor, would have neither the legitimacy of being born within wedlock, and therefore having the aproval of the church, (like all Andi's other children) nor that of having allready been emperor, albeit junior to the Megas Komnenos, before all this mess started (like Nik, and Alex, sort of) nor that of an extraordinary military record (like Alex, and to a lesser degree, Nik). Or that would be my guess at any rate.
Otherwise, I just want to inform BT that his writing is as good as ever and that I anxiously await the next update. For some reason, I want to see things turn out at least moderately good for Sybyslava and her children. This may have something to do with my suspiscion that dowager emperesses and their children rarely lived very long in these circumstamces.
Also, I would offer my help with a wiki if I wasn't utterly useless with anything more comlicated than MS word. And even that I'm mostly useless with.
