Inside the Train function, Jack was given the option to train using all the barracks, fighting schools, and magic schools, or only a portion of them. He chose all of them. The cost was 500 gold coins for each building.
Thereath had twelve barracks, ten fighting schools, and ten magic schools. This training cost a total of 16,000 gold coins.
Jack proceeded to do the same to the other settlements, except for village-level settlements which couldn't be drafted. In total, he spent 182,000 gold coins for drafting and 304,000 gold coins for training.
Aside from building, drafting, and training. There were two more city functions. Construct and Transport.
Construct was for making siege weapons and ships. Since in Themisphere only Thepergua had a port, only that city could produce a ship. The best ship available to construct there was the galleon, costing 4,000 gold coins and required fifteen days to construct.
