Here it comes! Amazon is starting a TV series based on the Lord of the Rings. But it’s not a ReDo, but a “Prequel”. Stories based on the “Second Age”. The stories, and movie collection, we are familiar with are based on the Third Age. Apparently novels were never written by JRR [Tolkien not Martin] based on the First or Second Ages, but he left a trove of source material describing these ages and much more besides. The Simarilion, published by his son after his death, is probably the source for much of the material describing these ages.
For a excruciatingly complete coverage of the second age, you might try this 35 minute video. As I watched it, I was not necessarily paying attention to the details as the broad sweep of the history and detail that this world building provides.
