Now that it appears the plot will be focused on the Rings of Power, I think Eregion will be a likely important location. This has piqued my interests in the series a bit, because I think the relationship between Celebrimbor and Sauron is a fascinating story to delve into.
There's not many details in Unfinished Tales: "The History of Galadriel and Celeborn" so I can imagine it's a story that appeals to writers who like having "creative license." But even so, it's a fascinating story in my opinion on Celebrimbor's friendship with "Annatar." Was Sauron at any point after serving Melkor sincere in repentance and his friendship with Celebrimbor? Or did he use Celebrimbor's shared ambitions and connection to play him a fool?
