Hi,
I asked me, where I can find the story's about Numénor. Or the story's of the upcoming LOTR series on Prime Video.
In the Silmarillion?
In the back of The Silmarillion there's a section called Akallabêth, which translates as The Downfall of Númenor. This is where you can find the history of Númenor. Enjoy!
In the Similarion
I would also recommend reading The Unfinshed tales, as there is a long chapter there called "Aldarion and Erendis"(a queen and king of Númenor)
What do you think?
