I make it a point in every game to exterminate every single Dw*rf from the map. There is no single race, not even the Sk*ven that deserves it as much, even if I play with the Empire I go out of my way to seek and destroy every Dw*rf stronghold and execute every manlet down to the last one, wherever they are hiding, no mercy can be shown to that most perfidious race of subhumans. I would even go to Lustria just in case they are still holding there, this is the real "Campaign Objective" of every single one of my campaigns.
