The Fallen Lords we know about are The Watcher (Bahl'al), The Deceiver, Soulblighter, Shiver (Bonesplitter), The Faceless Man and The Voiceless One (You may not agree on who I think Shiver is, but that won't matter).
Shiver is 'killed' by Rabican, The Deceiver is lost in a river (Dramus?), The Watcher is killed by the Legion, Soulblighter flees after Balors head is thrown into the Great Devoid leaving only two Fallen Lords (who I think are The Faceless Man and The Voiceless One). I think its at the end of Myth TFL where the narrator says that the remaining Fallen lords were hunted down and killed. Fallen Lords PLURAL. That means that there were at least two Fallen Lords hunted down and killed, and the only ones left were The Faceless Man and The Voiceless One so these two are now dead.
Thus, there are no more Fallen Lords left.
