I was wondering this, how is Skyrim, the gigantic, snowy place with evil walruses and magical skeletons only 20 odd years away from the place where Fallout, a Nuclear wasteland with no snow, no walruses and no magical skeletons takes place?

It is obvious it is only 20(ish) years after a Skyrim tale that a Fallout Tale begins, we can tell this as James is Poet's son and when his wife has Cywren, he is in his late 20s (We know this because when Cywren is 19, he is in his late 40's.

How do you guys think this happened? Did Cyrodil have a disagreement with skyrim and they had a nuclear war or something? This was at a time when there were stills castles and blacksmiths, I mean come on, it kinda seems a little ridiculous, please leave your theories because this has me stumped
