True, but this is a fantasy story, and in fantasy stories where the villain has a seemingly foolproof way of guaranteeing his return (and especially if he's done it before), you can normally expect the hero to find a way to defeat it in N-20 +/- 10 pages, where N is the number of pages left in the book.
This is a new thread to discuss Eliezer Yudkowsky’s Harry Potter and the Methods of Rationality and anything related to it. This thread is intended for discussing chapter 117.
Plans for next chapter release:
There is a site dedicated to the story at hpmor.com, which is now the place to go to find the authors notes and all sorts of other goodies. AdeleneDawner has kept an archive of Author’s Notes. (This goes up to the notes for chapter 76, and is now not updating. The authors notes from chapter 77 onwards are on hpmor.com.)
