So, i did some minor looking around and analyzing of the early footage for the teaser and i was comparing the possible architectures of all races to the ruins that you can see near the possible crater, (that may be coming in to play for this theory) it appears that the architecture is very similar to Breton and Nordic but Breton is newer as far as i know and Todd Howard stated himself about us wanting our eyes to see something fresh so maybe it'll be set in High Rock? I'm unsure and by far not qualified to be called a speculator but i thought of giving a possible idea, regardless if this has been 'proven' to be otherwise. Also, I couldn't find anything on meteor strikes ruining a city or estate of a wealthy owner so maybe I am wrong most likely but if you guys/gals could either help debunk or find more proof that this could be a possibility it would be great, enjoy conspiring.
