区域（region）是游戏中最高级别的地理组织，由 省份 组构成。
区域机制
Each region can be administered by a 
governor, who gives various bonuses or maluses to all owned provinces and territories in the region based on their traits and attributes. Additionally, regions are the fundamental unit by which a country's 
levies and 
legions are raised and organized. Each region in a country has a certain army 
strength based on its non-slave integrated culture population, which be either raised as a levy under the command of the region's governor or recruited to form part of a legion based in that region.
首都区域
The region containing a nation's capital city is the nation's capital region. The capital region is always governed by the nation's 
ruler, with the effects of his/her attributes and traits applied to all provinces and territories in the capital region as if the ruler was a governor.
Every state/territory in the capital region gets the following modifiers:
+0.05 Local Provincial Loyalty
Note that this modifier stacks with the modifiers for the capital province and territory.
As the capital region does not have a governor who takes a portion of the income, is more loyal than other regions of the state, and helps the ruler with their 
power base, full control is recommended before expansion elsewhere.
However, during a 
civil war, the territories where a rebelling character has 
holdings (even those within the capital region) will always join the rebels.
