Goruvich isn't much of a conversationalist either -- he's relatively civil towards the Ancient for the simple reason that he doesn't want the Ancient to flatten him. Still the easiest of the three to talk to, but saying a Khorne Berserker is easy to talk to is like saying it's possible to get blood out of a stone.
EDIT: Like your post, Dolnikan. I'll put something short up in a bit, with an aim of getting something longer done on Friday evening.
