[dancing spawn of ungoliant]

if there had become a "3rd dark lord" he (/she...!?)would had been just a weak copy(that's my opinion!).
melkor, one of ainur, was gone.
sauron, a maia, was destroyed with his ring.
the only "bad guys" left are orcs and some men.
orcs can't bild so good community that there could rise only one orc to rule the others...so what about the easterlings...err...gondor is too strong unless the blue wisards have something to do with the thing
