Wow! this idea as been in my head since I first found Tolkien (Hiding under a rock.. silly man). I often wondered, perhaps people would try and sail a ship to Valinor, and go off to the undieing lands. Or, more likely, they would make a wide rage of Valanorian products for all to buy and sell.
But seriously, perhaps it would then be taught in schools! AS history! Now I want a time machine to go to this future world of Silmarillion worshipers... wait... (Looks around the Downs...) hum...
Moreover, the elvish language might be taught like Latin is now. People would go searching in the sea for Meathos’ Silmarill. It would be a mad middle earth place… cool!
I think one of the Moderators will move this to mirth if we are not careful...
