^ Just on other NPC characters n the Inquisition, Mark mentioned in one of the thousands of recent articles that it even extends to things like making friends with the cavalry commander at Redcliffe and having him available to give extra quests on the Inquisition War Room table thing.
We've also heard about the Inquisition having specialist linguists and scholars to translate artefacts and ancient writings, that sort of thing, so I think there's actually quite a few important characters below Cullen/Leliana/Scribe Lady.
Oh, interesting point too about Scribe Lady probably being a master of politics and diplomacy, rather than just commerce - although Cameron Lee did say she handled merchants too. I suppose she'd be the one sending emissaries and writing letters to important people, or maybe meeting them in person.
