Talk:Four nations/@comment-1216259-20120811204633/@comment-5179242-20120827131635

The Four Nations "concept" is the historical and political correspondence of the four nations to their respective elements, and referred to how the Avatar did their job in sustaining balance and order between them.

The primary problem with adding the URN to this list is the fact that this page will undergo a dramatic but speculative change from Four Nations to Five Nations, and speculation is discouraged here. Your solution of saying that it is a nation that can be part of the four without really being one is also speculation. The URN as a mediator is still just assumption and not confirmed fact. Putting a category on the Earth article but not here exemplifies this "difference" you described better than writing it down on both pages and risking the input of speculative information. It is partially like the four, but in other ways it is not.

Furthermore, LOK has thus far ignored the concept of Four Nations. We have yet to see the show use it, which continues to make validating the URN's position more difficult.
