Ud n vs Utumno I think it s better to keep the two articles separate the only overlap of interest is Gandalf s phrase So I ve moved material from the former to the latter keeping links between them Also it would be better not to rely on the Encyclopedia of Arda as E of A has a habit of jumping to conclusions and not providing good references Do the work to find references in Reliable Sources or raise the issue with cn and the Talk pages For primary material plot geography etc primary sources are best so that we know where Tolkien said such and such An obvious exception would be places where Tolkien was not clear so that a good secondary source like Foster or Hammond Scull clarifying the matter would be useful
