Wikipedia:Articles for deletion/Dungeons & Dragons creatures
I think you're in danger of missing the forest for the trees.  From , "The number and nature of reliable sources needed varies depending on the depth of coverage and quality of the sources. Multiple sources are generally preferred."  I doubt you would dispute that each of the topics you've listed receives extensive coverage, and that's just IN the related material.  As the user above mentioned, there are non-WotC or TSR publications involved also.  Further, there is a large body of precedent for the individual aspects of largely notable works (e.g., the "Halo universe") receiving articles to discuss the details thereof. As I said above, there's no violation of the notability guideline here
