In 1018 YK, President Jack rose to fame for proposing the Dux Commercium Act, a 'trade don't ask' deal that proposed a neutral middle party to conduct the exchange of goods, imports and exports, between the First World and the New World. The act would favor a seamless tunnel between goods specifically found in respective worlds in bulk. First World with particular minerals, livestock, cloths and silks. New World with herbs, medicine, power sources such as crystals, and incense. The First World introduced the New World to the power of gunpowder through this way.
In 1019 YK, President Jack settled a city in the ideal location of the peninsula along Lake Galifar. Mainly consisted of merchants and entrepreneurs taking advantage of the Dux Commercium Act and by 1020 YK, Free City was founded.
The groundwork of its establishment falls along the following: Existing ruined factories from the old war, species of occupying humanoids being taken advantage of with an opportunity for better (not vastly better) living conditions and opportunities, a funneling of commerce that allowed rapid speed infrastructure and expansion.
Main Exports of Free City, Medicine, Coal, Fish, Gunpowder, and Silver, is what it can directly offer. But because of the bridge, it technically exports everything indirectly as it often has many storages of bulk purchase orders and supplies.
