The Medieval Engineers Planet has 6 kingdoms. These kingdoms are used as high-level divisions of the areas of the world. Because the kingdoms are very large they contain multiple Wonders and Biomes with all of the various Flora and unique environmental settings that apply. Kingdoms are used on the World Map as the top-level organization, above Regions and Areas.
Trivia: The first letter of each kingdom's name corresponds to the 3D face of the planet where the kingdom is located - Up, Down, Front, Back, Left, and Right.
The pages in this category generally do not contain much information. The pages themselves are important in the context of other pages, such as biomes or flora, that link to them. This way, if you are looking at a biome you can see what kingdoms it is in, or you can conversely find all of the biomes contained within a particular kingdom. The links between Biomes, Flora, and Kingdoms are the web of connections that describe the Planet.
