Well, Amazon is providing us with a lot to chew on. I that we cannot be certain where Amazon is taking this given the info so far.
Our map hints are located here:
https://www.amazon.com/adlp/lotronprime ... l-T16CsCtUThe latest map (revealed today) does not simply have new additions, like Numenor and Ost-in-Edhil (that, with the poem, allude to the crafting of the rings with Celebrimbor), but it also has removed (e.g. Arthedain cities) or renamed (e.g. Moria) prior map locations. So what can this mean?
Given that the only thing we know for certain is that the show is set over 5 seasons and the fact that 5 maps were provided, my latest speculation is that each season will cover a different historical period (reflected in the map).
I will go with the "last (map) shall be first" theory and season 1 will cover the forging of the rings of power and the downfall of Numenor (though that is a hell of a lot to cover).
Season 2 (second to last map) may skip forward to the turbulent years of the end of 20th century of the Third Age when Arthedain falls (TA 1974), Angmar is defeated (TA 1975), Khazad dum falls (TA 1980), Galadriel & Celeborn rule Lothlorien (TA 1981) and maybe even to the siege of Minis Ithil (TA 2000).
Season 3 (third map) is more nebulous. Perhaps we move forward 500 years to invasions of Gondor by the Balchoth, the intervention by Eorl the Young and the founding of The Mark of the Riders (aka Rohan).
Season 4 (second map) I have no clue about. I would like to see this be the season we see a young Aragorn, but the map still shows the region of Rohan in its earlier, Gondorian name.
Season 5 could move things into the Fourth Age and the passing of the kingship to Eldarion.
The thread connecting all of these seasons could be (should be?) the lives of the people in the line of Elendil & Isildur. So in each season we are following the events from the eyes of one member of this family's lineage.
