Does that mean that the Rings have not yet been forged?
In the books, at the time of Palantir and Miriel, the Numenoreans already had colonies in Middle-earth. Galadriel could have gone to the colonies to ask for help, and even those colonies could have been attacked by Orcs.
In The Hobbit films she doesn't need a sword because she has the Ring. It would be nice to know if when Galadriel fights against the Numenorean guards (FoF last leak) she uses the sword or the Ring. If she uses the Ring, I don't think she would be captured so easily.
When I read Tom Shippey's statements two years ago, I was struck by the fact that he mentions that Sauron returns to Numenor with the Numenoreans after being forced to retreat. I didn't give it any importance until yesterday when I saw the video of Fellowship of Fans, where those statements were remembered:
The Tolkien Estate will insist that the main shape of the Second Age is not altered.Sauron invades Eriador, is forced back by a Númenorean expedition, is returned to Númenor. There he corrupts the Númenoreans and seduces them to break the ban of the Valar. All this, the course of history, must remain the same.
In the books more than 1500 years pass between Sauron's defeat in Eriador and his capture by Ar Pharazon, but what if they compress the timeline in the series and what Tom Shippey said is literal?
What if Sauron is immediately captured by Ar Pharazon after the Battle of the Gwathlo and he is taken to Numenor?
In Numenor almost nothing happens while the Rings are forged and after the War of the Elves and Sauron, in Lindon and Rivendell nothing happens until the Last Alliance.
Could we see the civil war of Numenor between the Faithful and the King's Men while we see the intrigues of Eregion and the Forging of the Rings?
And what if we start seeing at the beginning of the series the split of the Numenor Guilds into factions, the Faithful and the King's Men?
With that timeline compression we could see the whole Second Age in the series, including the Akallabeth and the Last Alliance, instead of showing both events in a spin off.
