Harbat relies almost purely on trade and during the course of its existence it has developed a myriad of complex rules that define and regulate free trade for all, coming up with some interesting laws (such as "the law against heroism"). Trade is a lucrative business here, attracting all the necessary shady characters as well.
The Harbat harbour is a very busy place. Ships mooring, crates unloading, barrels rolling, and the harbourmaster inspecting all of it carefully. Carriages stuffed with cargo go to and fro the wharves, dusty miners shuffle home in exhaustion, an ear-pounding racket emerges from the lumberyard. And off in the distance stands the impressive airshop workshop.
The harbour has two docks. One is used for seaships and is situated in the water below and is generally referred to as "the pier". Here seaships moor for loading, unloading, and repairs. There is an odd old pole of some sort here as well. The other dock is used for airships. The docks are in constant need of repair.
Behind the docks, through some streets, lies Offing square, a particularly interesting part of the market that has a warm welcome for newcomers on foot. You can already see it from where you're standing (there is a little street that bypasses the square, where the fishnet menders have their workshops and the trade guild holds quay, but that would be an enormous walkaround).
All of the buildings at the docks look great and grand, with many busy people milling about. Most of the town's guildhouses are stationed here: like the miners' guildhouse, the fisherman's guildhouse - a beggar propped against it - and the painter's guildhouse. And some establishments as well, like the brewery, the jig and the corner innhouse.
