An advanced sewer system and water supply made of Mica "Wiley" of the Nine's new plastic was installed underground before all construction in the valley of Nexus Prime and Micadonia. Simple versions of in-residence plumbing are gradually coming into use as well. As a result, the filth of the big city is much less appalling than might be expected.

The Great Shipyard stretches along the waterfront of the Old City from the Rendezvous Bazaar to the Great Southlake Park. Mostly at present it is building Hammerships, but with the WATC funding generated by the Hammerships it is tooling up for more hull styles. Captain Tatharandar Windsong is teaching the shipwrights how to grow custom Elven hulls.
Just North of the Shipyard, straddling the Great Gate Road that divides Micadonia from Nexus Prime, on the East Bank at the end of the Great Bridge, is the Free Imperia's largest marketplace.
Patrolling the Bazaar is a responsibility of the Paurgiliath Peacekeepers, who aren't as hung up on the letter of the law as they are on Ethical Behavior. As a result, while it has a predictable waterfront Grey Market happening, it is a remarkably well mannered marketplace with very little petty or violent crime.
