The nations will be starting in a time period where much of technology still needs to be discovered and invented, although nations will have different starting advantages based on the descriptions you provide.
Descriptions are primarily for determining how the people will react to various events that occur within the civilization.
Name: The Kingdom of Shwartz
Administrative Capital: Shwartzburg, City of Light
Ruler: The Mighty and Omnipotent Shwartz99, Father of EpicMafia and Master of the Four Lobbies
Description of Peoples: People in the capital of the Kingdom of Shwartz are typically wealthy, as it is home to many trading houses. Wealthy people are also happy people! The central government of the K.S. is made up of mainly templars who do the normal governmental tasks, all controlled by King Shwartz99. Ordinary citizens have basic rights. Imported slaves (criminals and prisoners of war) are trained to fight in the gladiatorial arena next to the ziggurat in the capital, while the king watches from above.

The Kingdom of Shwartz also includes land outside of its capital, which has partly been turned into farmland. As of now, there have been little problems for farmers and the whole kingdom has a surplus of food, but that may change in the future. As the map has not been created yet, it would be foolish to go into greater detail on land use in the K.S.
Shwartz99, the king of this realm, understands that happy people are ones with rights and food. He tries to maintain order by providing these for the people, as well as entertainment via the gladiatorial battles in the arena. Although his templars may find him just, he only does what he deems is necessary to keep himself in power. He is unmarried and does not have an heir, although it is uncertain how long he has been ruling or what happened to his predecessors.

I would like to be the Bogdanian Federation, ruled over by two god-kings known as the Bogdanoff twins.
