Without a doubt, Bethesdas decision to reveal a teaser trailer for The Elder Scrolls 6 during E3 2018 not only generated a groundswell of excitement around the long-running fantasy-RPGs fan base, but also caused them to breath a sigh of relief to know that its still in production. This also means that we dont know where exactly in Tamriel the game might be set. Is it possible that the trailer just went with a generic fantasy landscape, and that the final location where the game is set might not have been decided yet?
