I think that the next elderscrolls should be in Elswyr, cause that seems the most logical direction to go. we’ve seen the jungles, forests, volcanic regions, and mountains...now we have to see the desert. i dont know what the premise would be, but im sure bethesda could think of something really good. i could just imagine sitars and middle eastern type soundtrack with an elderscrolls ambient twist and whatnot. and they could make the deserts look beautiful, have oasis in places, more stars than you’ve seen at night and beautiful environments. plus the creatures and sandstorms would be there. the kajhiit said there were cities so ancient that the sands have swallowed them whole, so that could be a new type of dungeon exploration.
Now Black Marsh, i could picture a story for, but idk when theyre planning on that. the marshes could be very “avatar-ish” and more elderscrolls touches everywhere. they could make this a very lively environment. But maybe theres a wall up around Black Marsh cause theres a viral outbreak, not necessarily zombies, but something unique and with a twist, so everyone inside the marshes is in danger. your character could be immune or even a carrier, maybe you’re the reason the outbreak started cause u escaped an experimental prison. the whole twist though is that you get out and all of tamriel’s already infected and they only have a short time to find a cure, which ironically is back in Black Marsh, so u have to lead a group back in and its complete chaos. I could picture there being a magic set of ruins or a fountain that controls the weather all over tamriel, so u have to take the cure there, but there’s a religious group called Black Rain that thinks this is the way the world is supposed to end so they’re trying to make sure it happens. They activate the Black Rain briefly which could look very cool like bethesda likes to do, and when u put the cure in, each rain drop is a different color and the clouds look like water with rain drops falling on it. The music could be very beautiful for this achieving moment.

i just hope they dont do another human province like the bretons or redguards. that would piss me off. they can do anything else besides that. Dont get me wrong though, i would play the [censored] out of it and would love it, they just need to mix it up a bit. i loved skyrim more than any game ive ever played and the nords were my favorite humans. they fufilled a bunch of wishes when i started elderscrolls, like in morrowind on the island of solstheim, i fought a nord who spoke of sovnguard and it was the first time i heard of it and always wanted to go...guess what i did and i was blown away. i loved it and Blackreach......that was just fufilment of mystical realms of existence from my childhood. i always kind of pictured that sort of look when someone mentioned fantasy and blackreach blew it all out of the water. i still go down there constantly and just walk around, usually bringing the drunk, Cosnache with me, cause hey...he’s a badass. But either way...Elswyr all the way for the 6th!!!!
