At first i thought the whole story was the dream of dokja, but when in the end someone which is even older and even threatened the most ancient dream appeared, which made me question the world which encompasses the entire story. So i was confused.
Not sure how its confusing. Dream or not, if you look at Novel's Extra. At the end you find out that his universe that was created based on his book is in the mid-lower end of the scale and that the co-author being on the lower end of the universe creation metric didn't have the power to create a better universe which would have been on a higher scale. Thus despite being a god and all powerful universe was still below the level of other gods and universes. So why can't it be the same?
