I Believe Tolkien's Unfinished Lord Of The Rings Sequel Was Secretly Trying To Set Up Morgoth's Return

The Lord of the Rings has a little-known and unfinished sequel that I think may have involved a cameo from Morgoth, or even a potentially large part. Renowned British author J.R.R. Tolkien published his magnum opus, The Lord of the Rings, in three parts between 1954 and 1955. Sauron was the eponymous Lord of the Rings in this novel and the main villain of the story. It wasn't until the publication of The Silmarillion in 1977 that readers got to know a little more about the Ainu that may have returned in The Lord of the Rings' incomplete sequel.
