'image' - path to the image for the list of kingdoms. 'post_selection_description' - a localized description that will appear in the text at the left side of the screen after we select our kingdom. 'description' - localized description that will appear in the list of playable kingdoms in the UI. Nevertheless, a '(favored)' text will appear next to the biome name, so that players know that in that biome they'll have all the resources for this kingdom's jobs. The warning will only appear if we chose a vanilla kingdom that's not favored.

When players choose to play with this kingdom in a non-favored biome, a warning will appear in the UI.

Normally favored biomes provide with enough resources for the base crafter job of your custom kingdom. 'favored_biome' - URI of the favored biome. Try to keep it unique, and only use lowercase and underscores by convention. 'kingdom_id' - an identifier for the kingdom. 'display_name' - localized display name to show in the UI. 'type': 'kingdom' - this file represents a kingdom / population. Let's check the properties that we can find in these files: We can copy an existing population JSON file, they're usually inside stonehearth/services/server/population/data (for Rayya's Children and Northern Alliance mods, they're inside their data folder). The steps for adding monster populations are similar, check this other page. To add our new playable kingdom we can take a look at the rayyas_children and northern_alliance mods. Kingdoms are managed through the population service, population call handler, and population_a.
