Doralingus should be in charge, but honestly it would be easier to get a pack of kittens to stand at attention and do jumping jacks. Walken does provide the quests, true, but he doesn't really appear to do any decision-making beyond that. The only one who does is Neebs. He's a total idiot, but he pretty much determines what Domaleous and Associates does (or is forced to do) in any given situation. Doesn't mean he actually directs things as such - he's like a one-man Waaagh! on that point - but he did land them that gig with the Pyramites, got them thrown into the dungeon, signed Dolaleous up for the gladiator tournament, the list goes on.
