This is our root category. Here you will find all basic topics of this wiki. Ideally, every other category should be a subcategory of at least one other category, and every article should be in at least one category; many will fit well into two or more. A full list of existing categories can be found at Special:Categories.
Articles about alien species, locations, characters, substances, etc... can be found in their respective categories and should not link here directly, but pages concerning the wiki community and administration might. If a category already covers a main topic and does not fit as a subcategory of any other (e.g. Category:Alien Species, Category:Locations, etc...), it appear here directly.
