It seems to go in that rout but the fact remains that the lore is unfinished. And we know its unfinished cause Silmarillion was formulated by his son cause the book was scrapped from all the stories that Tolkien made that he didnt finish cause of his death (I dont know if he ever planned it to be finished to tell you the truth), most of them having no chronological order until his son helped with that. And it would be very difficult to expand uppon that lore given the fact there will never be people like JRR in the world ever. We can only do small protions of what was given to us, but nothing major like he did.
Silmarillion is a good read, and it does explain a lot of things about the world, but it falls flat when it comes to the people, which were many that I lost track of, im sorry but it was.
