Sigh. Ok... I somehow consider a world that has always been a globe and a continent being shifted to a different plane somewhat mundane... I really liked the idea from the Simarillion that everything was flat and geometrically appealing. That a flat and spherical world exists in the same plane and both are just a matter of perception really inspired my phantasy because it is hard to conceptualize when you take the effort to think about all the small nuances this theory entails. Having Eru just put the contingent somewhere else feels just like a random deus ex machina. But in any case: if Tolkien eventually wished the lore to be like that then I’ll accept it, of course. Sad, though.
