Thorondor's fate is equally uncertain. The only clue is a passage that appears in The Lord of the Rings, referring to '...old Thorondor, who built his eyries in the inaccessible peaks of the Encircling Mountains when Middle-earth was young.' It's plain from this that Thorondor departed Middle-earth some time after the end of the First Age. Perhaps the greatest Eagle of them all simply died of old age, but his mighty body carried a spirit sent by Eru, so perhaps, just possibly, he flew back to his master's halls on Taniquetil and still soars in the airs of the Undying Lands.
