Golems - maintaining city? Only parts?
Pilgrimages. Definitely.
Guard forces. Private? Automated? See Golems above? Hierarchy? The City loves hierarchy.
Armies? Definitely. Private ones. Per sub-city (public). Per region? Province?
Pirates? There are large bodies of water - of course we have pirates!
Clockworks? Probably in the Boilerworks. Clocks? Trains? Automatons?
Mines? Not much to find, easier to conjure. Some family-run mines exist.
Undead? Would perhaps make most sense in Zil-Shahaar. Et-Gong has several prominent, undead officials.
Ruins. Orgram? Definitely Suno-Haiinah.
The Winding - almost like a gigantic open-pit mine. Terrace upon terrace descending into the ground.
The Celenes - demistate of lesbians?
Zil-Shahaar - sub-city so consumed by industry it never sees the sun.
The Underside - entire subterranean sub-city, hidden beneath the surface under a regular sub-city.
Zil-Shahaar - slaves.
Zil-Shahaar - Sub-city of silence. Speaking in public outlawed long ago. Sign language used. Kids gagged or magically silenced.
Tribes of Giants - Northwan, of course.
City of boats - giant city of houseboats, ever changing. Et-Gong.
The Greens - Elven city center, cutting of trees forbidden.
Black Market - Zil-Shahaar and Raszhan.
Wyrmwood - traveling city. Sometimes on the back of a giant turtle, other times slowly growing out of ground, being constructed by a traveling circus, occasionally shows up within other cities 'having always been there'.
City of Oracles - Thelaash - gases in the air causes halluciations.
The Black City - an enormous cube of black onyx inside which a city is carved.
The Great d4 - an enormous black pyramid decorated with gold. Sits alone in the deserts of Raszhan.
Surviving a night in the necropolis in The Winding grants some measure of undeath.
