Games like pocket city

Recently user 205.188.117.67 moved several of the planes in this article to different levels, for example:

The problem is neither the original nor the new have any sources. What we need her are references, and in the lack of any other references I am about to move Orcus back as he is clearly referenced as 333 in module H4 The Throne of Bloodstone.

I am sure there is some condratictory info in different sources (this is fictional after all) So I propose the following precedence of sources as the primary entry (alternatived can be noted at the end of an entry)

Within any level the order of precedence should be most recent highest. Referenced material (Product with date and page prefered) always takes precedence over non referenced.
