* AuthorExistenceFailure: Tolkien died before he could finish it. (But he spent years and years fiddling with the stories, so the published version is an editorial creation, assembling together various texts into a readable version that doesn't contradict itself.)
* DevelopmentHell: Tolkien began writing ''The Silmarillion'' during the FirstWorldWar and it was published only in 1977, over sixty years after its first conception.
* SavedFromDevelopmentHell: J.R.R.Tolkien worked on it from WWI to his death - over fifty years! - and it was published posthumously by his son Christopher in 1977. Most Tolkien fans agree it was definitely worth it.
* NamesTheSame: In RealLife, [[http://en.wikipedia.org/wiki/Ainu_people there is a culture of Edain called the Ainu]].
* WordOfSaintPaul: Christopher Tolkien's commentaries and edits on posthumous works. Also his version of the war between Doriath and the Dwarves, which his father never got around to writing.
