You misunderstand the point of using categories. The quest page themselves do not go into the Category namespace.

For example, the quest name is "A beginners guide" it goes under a page named "A beginners guide" and not "Category:A beginners guide" HOWEVER, on that page it would contain " " which would add it to the Quests category, which in turn would be a page listed by categorytree through the use of mode="all" or mode="pages". So this hierarchy is an example set-up, with namespace prefixes, of how this listing is achieved:

Category:Quests
 * A beginners guide
 * An intermediate guide
 * An expert guide
 * Category:Act 1 Quests
 * Prologue (Act 1)
 * A simple sighting
 * Capturing the sighting
 * Category:Act 2 Quests
 * Prologue (Act 2)
 * A simple dish
 * Making that dish
 * Category:Easy Quests
 * How to use cheese

Any page (not prefixed with a namespace) will have the parent "Category" on it (ie: marked as Category:Quests) and that page itself would exist in the main namespace (no prefix) Any category will belong to the parent category as well, similarly to pages.

please note that all of those page names were made up and may not actually make sense for the wiki you wish to use this on, it was to convey the meaning.

If you wish, I will head on to the wiki you posted originally and create some categories for this to be, perhaps, better shown.
