Categories help the reader to find articles. When writing an article, use the most likely categories in which the reader might look for a given article, even if they don't know that they exist or what they are called. An article's categories should reflect the topics and classes that are directly related to the subject. Every page, except for redirect pages, should belong to at least one category. Include pages in as many categories as are applicable to that article.

Categorize categories, too! That is, add categories to at least one relevant parent category in order to build up the category web. Top-level categories belong to the Category:Content category if they contain articles or the Category:Images category if they contain images. If they contain both then add them to both!


Category names are always plural, where this makes sense. For example, categorize articles about an item in Category:Items and not Category:Item. However, articles about equipment should be categorized as Category:Equipment and not Category:Equipments, since equipments is not a word: both the singular and the plural are both equipment.

Red linksEdit

Categories are often thought to be unused if they show up in red colour when trying to link to them. Like all other types of pages, category links will only show up in a non-red colour when content is added to them, but unlike almost all other types of pages, categories can still be in use even when they are linked in red. This is because pages can be added to a category whether or not the category page itself has any content, so categories will still show in red even when pages exist in that category. Clicking red category links will still show you all the pages that are in that category, whether the category page has any content or not. Red category links remind you that the category has not been assigned to an appropriate parent category yet.


Editors often desire to put something into category pages when they know that it is in use, in order to mitigate the problem of red links. Generally this is a good idea, but many editors do not know what they should put into category pages. Categories are pages in their own right and as such you can potentially add any content to them that you could to any other page. In spite of this facility, in general, content should not be added to category pages. Content about any topic should be placed into an article page.

The first thing that should go into a category page is a link to another category! This is known as the a parent category. Parent categories helps to build up the web of information by linking hierarchically to one another. If the category that you want to add a parent category to does not logically belong to any parent then add it to the Category:Content category. This is the highest level category that a regular content category should be contained within.

Sometimes you might place articles in a category for which there is also an existing article with a similar name and purpose. For example, if you are writing an article on a particular quest, it would be logical to categorise it in a category named Quests. However, there is also an article named quest. In the interests of making it easier for readers to find useful, related information, it is helpful to create a link from the category page to the article. To do this, use the {{main}} or {{see}} templates. In this example, you could insert {{main|Quest}} into the category page.
