Why is the Empress' Palace shuttered? - "Apparently the Empress doesn't like light. Or sudden movements, loud noises, foreigners, treason, peaches. When you're Empress, you can do this kind of thing."
What's it like being a Tomb-Colonist? - "Halfway between being a leper and being bankrupt. They're difficult, these people. You never know quite what to say to them. 'How are you?' rarely goes down well. Down here you can't really talk about the weather, either."
What are the things under the City? - "In no particular order, these are said to be: the first Four Cities; the Masters' summer homes; the hatcheries of the Rubbery Men; and a number of gigantic sleeping beasts which are drugged every year to prevent them awakening and destroying the Neath. These are sometimes referred to as the 'stone pigs', but that's probably some sort of mistranslation."
Ivory Towers? - "You can study many things at the University of London. The Department of Cryptozoology studies the small, hidden creatures of the Neath. Creatures that have never been seen, but almost certainly exist. Under the right circumstances. Hopefully. Otherwise the Department might lose its budget."
