The following categories exist to better categorize the wiki's articles by in-universe region or country. The regions are probably states or larger, unless there are a lot of articles in the category (in the instance of Club Penguin). For smaller regions, check the individual categories (i.e. Category:Mattress Village isn't here, but is located under Category:Eastshield, which is here).
This category has the following 21 subcategories, out of 21 total.
