What you are saying goes completely against everything what is described in the bear. You cant kill all the kids that can hold the sword, all the old, all the nords and all bretons and then have them nice and alive or alive and spared or anything like that. It is said they are dead, murdered by Ulfric, why are they alive?
They have no idea that Silver Bloods have anything to do with Forsworn, all they want is cidhna mine and they dont care how they get it.
As for Nepo, yes he is the contact, a very important person if I am not wrong and a prime targer for execution by Ulfric. But he lives
?
People move, that is right, but Winterhold couldnt recover in 200 years but markarth did in 20 :/
Really man?
Silver bloods use them for geting rid of oposition yes, but your General doesnt know that, they werent used like that when Ulfric took the city, and it wasnt silver bloods that Ulfric listened or helped, it was Igmund.
