An Elder Scrolls Online fan has gone datamining through the latest version of the game and believes he knows what region Bethesda is going to be adding next: Vvardenfell from Elder Scrolls Morrowind.
Redditor “FloorBelow” has found tilesets within the code for Hiaalu, Redoran, Telvanni, Vivec and Molag Mar, as well as data for Dwemer ruins and Dunmer strongholds. From his post:
That covers pretty much every architectural style in Morrowind, except for Imperial towns and castles, which don’t exist since Morrowind isn’t an Imperial colony yet. Oddly, Seyda Neen does exist, and is using custom assets that make it look exactly like it does in TES3. I’m sure that’s going to be a fun nostalgia trip.
The whole area around Red Mountain appears inaccessible, though the northern ashlands around Urshilaku are, along with Molag Amur. Sheogorad looks to be heavily under construction, but that giant wall of rocks makes me think it may be inaccessible as well.
There’s a Redoran town around Andrasreth that didn’t exist in Morrowind. There’s also a Hlaalu town and a Redoran(?) village near where Caldera will be. Weirdly, Rethan Manor seems to exist, despite the fact that it was built during Morrowind.
The Telvanni towers all have big mushroom caps like the one in Dragonborn. Interested to see how that turns out.
Vivec’s foreign quarter appears not to exist yet, which I think is a neat touch. There also seems to be a port/outskirts around the future site of Ebonheart, which is awesome and makes it look more like an actual city.
Finally, a size comparison between Vvardenfell, Wrothgar, and Stonefalls. It’s definitely going to be the biggest PvE zone in the game so far, even without Red Mountain being accessible. My best guess is that it’s going to be just under twice the size of Wrothgar.
