This theory does have credibility behind it. I have missed quite a bit of all three series, but based upon my knowledge of them this does seem like a plausible idea. Concerning the "step down" in technology, it could be either that all weapons seen in Fallout were considered "illegal" and taken away, replaced with medieval weaponry, or if it all simply deteriorated and was lost in time. On another note, the Lord of the Rings films and novels take place in roughly the 3000s, which means they are in the future, so it isn't entirely impossible for this to be a citation for the continuity of weapons and tech.

Another though I had was that the Brotherhood of Steel was, in itself, a time-traveling organization, and they somehow went back in time and planted Nirnroot and it has a larger part in the universe than we think (Jordan would agree that it does), or something along those lines.
