OKAY so just another note,
@Azel especially since we'll be leaning on you for the "sort out everyone and get whoever to follow your orders for city managing shenanigans".
We need to set the dragon pens to making copies of the entire hall of records. Thaaat could have gone badly. Doing similarly and storing one from each conquest for central administration would be wise.
Though thinking further some kind of information storage system that does not rely on records being burnt to a crisp would be wise, though we
could go the way of the Administratum and have hundreds of thousands of bureaucrats working a confusingly efficient or efficiently confusing filing system, it would be much better not to have millions of documents to sort through on an average day.
