Greenharbour is the largest settlement of Tribe Deathwater, located on the island of Mother to the north of The New World. Most of the city is a shanty town, built haphazardly from the wreckage and wood brought ashore by the local Greenskins and their slaves. The city boasts a sizable dockyard, used to build and repair the growing Greenskin fleet. At its centre is the Hall of a Thousand Captains, built from the hull of an overturned Imperial warship, that houses the Captain-Chief when he is in residence, as well as the Greenskins permitted to speak in the tribe's debates.
