LOTR does not count. IT IS A DIFFERENT UNIVERSE.

From this Wiki :

" Wherever they may have come from, they have long since died out as of the present, as they were eaten long ago by the  Tsaesci  ("eaten" may not refer to literal ingestion - some believe that the Tsaesci merely assimilated the Akaviri).  [source?]" 

From UESP wiki :

 "No  mer  have ever lived there; the men that did live in Akavir were all "eaten" [Note 1]  long ago by the Vampiric Serpent Folk of  Tsaesci . There are four major nations on Akavir, each with its own race. [3]" 

The Blades are the Dragonguard, in case you didn't know. Delphine and Esbern don't count, they are stupid idiots.
