True we can't know, however in many of Bethesda games, depending on lore they put it, they put strong hints at the next areas they are considering, or content. Example in oblivion, we kept hearing about troubles in the Summerset isles and about a uprising, come Skyrim and we got the Thalmor. In Skyrim they have described Elsweyr and Valenwood a lot, such as talking about the walking city in Valenwood having taken root for the first time since the dawn of time, and the kahjit explaining the layout of there land, and about the "vast buried cities underneath the sands". I am in favor of the Valenwood/Elsweyr combination, as both countries are relatively small, and they have connecting lore because it is said Elsweyr is a barren desert because the kajhit angered the goddess of the forest, and she awarded her favorite children, the wood elves, with the lush forest of Valenwood. In addition to the Thalmor basically taking control of Valenwood, so the story could have two or more focuses, such as the Wood elves fighting to reclaim the forest from the Thalmor, and then the mystical story could be about the goddess and curse she place on Elsweyr and this somehow relating to the giant tree city that was moving since the dawn of time stopping.EHKOS said:Can we stop this? No matter how many threads, no matter what province is said most, Bethesda will decide in the end and no amount of talking about it is going to change that. We have at least two years before the next one comes out. This is the tenth thread I've seen about this.
Personally I don't think there is much chance of black marsh, as only a little lore about the place is know, and no new topical events have come up in skyrim about it. All we know is is dangerous as hell, has really deep swamps, and is rumored IN GAME to have a species of sentient trees known as the Hist, and that some argonians worship these trees. Only story I can see is the trees deciding to go genocidal, and you must become the legendary histborn, and fight off their army of tree hugging hippies(I apologize for the very very bad joke)
