Harry Potter and the Methods of Rationality discussion thread, February 2015, chapter 110

Gondolinian

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 110.

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.)

Spoiler Warning: this thread is full of spoilers. With few exceptions, spoilers for MOR and canon are fair game to post, without warning or rot13. More specifically:

You do not need to rot13 anything about HP:MoR or the original Harry Potter series unless you are posting insider information from Eliezer Yudkowsky which is not supposed to be publicly available (which includes public statements by Eliezer that have been retracted).

If there is evidence for X in MOR and/or canon then it’s fine to post about X without rot13, even if you also have heard privately from Eliezer that X is true. But you should not post that “Eliezer said X is true” unless you use rot13.

Regarding Chekov's Elder Wand:

We have been repeatedly told about Dumbledore's "long dark wand" (Ch. 56,57,77,81,94,110), a "wand of dread power" (Ch. 77), which we know from Canon is the "terrible device" Grindelwald possessed (Ch. 77). In Azkaban (Ch. 57), Dumbledore confirmed this:

"Nonsense, my dear," the old wizard said cheerfully as he strode off yet again, waving as though in admonition his fifteen-inch wand of unidentifiable dark-grey wood, "I'm invincible."

Query: A key point in canon is the mastery of this wand. In this universe, Voldemort!Riddle has defeated Dumbledore before the latter threw the wand away. Does that make him the master of the wand?
