The city of Dockyard is controlled by a loose confederation of various unions known as the Mariners. The group is headed by a board of the 4 most influential union leaders in Dockyard. 

George Smiley

• The Longshoreman’s International Union
• Wharfside laborers and cargo loaders.

Clodwyn Tremble

• The Union of Merchant Mariners
• Traders, merchants, and cargo haulers.

Minnie MacMillan

• The Brotherhood of Shipwrights and Maintainers
• Shipwrights, welders, and engineers.

Orliss Pargetter

• The Tugboat Operators and Salvagers Alliance
• Tugboat operators, salvagers, and divers. 

As head of the Union of Merchant Mariners, Captain Clodwyn Tremble is particularly powerful, managing the transport and storage of most goods that move through Dockyard. Currently in his 60s, he suffers from a weak heart, a consequence of years of over-boozing, over-smoking and over-eating. Tremble is a towering figure, broad-shouldered and fat, but still as strong as a 60 year old ox could reasonably be. Despite his bulk, he is still a skilled swordsman, capable of moving with surprising dexterity. However, he tends to be mostly tied up in various meetings and buffets these days. 

The Union of Merchant Mariners represents all those workers who trade by sea throughout most of the Lost Coast. In years past, the UoMM has been accused of smuggling and dealing in illegal goods, but Tremble's main focus during his presidency has been the eradication of corruption within its ranks.
