This is where the denizens of an encampment come to meet and make their arguments heard. The constant bickering and backstabbing that occurs here is necessary, however, for it keeps them from killing each other in the street. The Town Hall is also where the encampment's Overseer can keep a close eye on the resources and funds that are available, and use them as he sees fit. All shipments of wood and gold are brought here for his inspection. This is also where peons are given the training to do the simple tasks demanded of them by the Orcish empire. Blackhand has ordered that only one Town Hall be allowed to stand in each encampment, so that separate factions of Orcs will not arise. If the Town Hall is destroyed in battle, another can be built to replace it.
Town Halls are the center of your city; harvested lumber and mined gold is sent here to be collected and used. Other than that, this building trains Peons and builds Roads and Walls.
As the Manual states, you can only have one Town Hall, but it can be rebuilt if destroyed. However, the computer player can have one Town Hall per settlement, as can be seen in the later missions of the Single Player Campaign. Black Rock Spire also functions as a Town Hall, though it cannot be rebuilt.
