This category is the mother of all categories. In other words, all categories on GuildWiki should be (sub-)categories of this one.
Yu can use it to help you find a proper category for your page - just drill down until you can't find a more specific category that fits.
This category should eventually be the only category in Special:UncategorizedCategories.
