Ahh... shame. My hint there was for you to change your mind.
Frankly this place is relatively meaningless to you, Talin. They speak of this being the centre of the Kingdom's wealth but you cannot actually see even any gold around, let alone mithril.
(I'm not saying Dwarves have no concept of economy but they do pretty much base it around the 'look at my huge pile of treasure' model, and any accounting would be done adjacent to that money)
That being the case, Menelacar, as a man of good breeding you are in without any trouble. Now, this place is large and ancient and not entirely well kept (not ill-maintained, but just cryptic, as is the way with old stuff). So! What is being searched for?
Meanwhile, a cursory look at the records mostly confirms what you have already. Seinost pays the most tax, Annuneryn the least; Halatir seems to own a lot of land but doesn't pay anywhere near as much as Seinost, which means, presumably, he doesn't take in as much.
One thing you do notice, though. Annuneryn owes a lot of money to the treasury.

A crowd is gathering, of course.
