Deletion of Spirit World (Avatar: The Last Airbender)

Comment: While it needs improvement, there are other articles in the same vein--see:Category:Avatar: The Last Airbender nations -- and AfD is not a substitute for improvement.  I know my argument is somewhat against , however, if this article fails  then the others in the above category would too, and I don't see that would be quite appropriate, as the other articles are well-written--and that is really all this article needs.  At the very least, I would say, give this article another stay of execution so long as there's someone willing and knowledgable enough (where to find sources-wise) to do the work
