So last night my son asked me who created the world of the Hobbit and I said “JRR Tolkien” and he said “no like who created it the way Aslan created Narnia” and I said “Eru Iluvatar” and he said “I want to read that story” and I said “o boy my child my son do you have any idea what you just asked for”.
Good taste.
The Ainulindalë isn’t that long.
I was reading “Plus also all of the Silmarillion” but maybe that’s just my interpretation.
