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Eliezer Yudkowsky which is not supposed to be publicly available (which includes public statements by Eliezer that have been retracted).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.

The source of the Harry-Voldemort resonance is that Harry was made into a Horcrux of Voldemort. Chapter 108:

The prophecy seemed to hint that if I destroyed all but a remnant of Harry Potter, then our spirits would not be so different, and we could exist in the same world."

"Something went wrong," Harry said. "Something that blew off the top of the Potters' home in Godric's Hollow, gave me the scar on my forehead, and left your burnt body behind."

Professor Quirrell nodded. His hands had slowed in their Potions work. "The resonance in our magic," Professor Quirrell said quietly. "When I had shaped the baby's spirit to be like my own..."

Harry remembered the moment in Azkaban when Professor Quirrell's Killing Curse had collided with his Patronus. The burning, tearing agony in his forehead, like his head had been about to split in half.

"I cannot count how many times I have thought of that night, rehearsing my mistake, thinking of wiser things I should have done," said Professor Quirrell. "I later decided that I should have thrown my wand from my hand and changed into my Animagus form. But that night... that night, I instinctively tried to control the chaotic fluctuations in my magic, even as I felt myself burning up from inside. That was the wrong decision, and I failed. So my body was destroyed, even as I overwrote the infant Harry Potter's mind; either of us destroying all but a remnant of the other.

I saw that, but didn't see an answer in it.

"When I had shaped the baby's spirit to be like my own..."

...? And?

Quirrell describes the series of events, but provides no causal model that I see.

So you think that if Quirrell had tried to make a Quirrell imprint horcrux of any other person the same thing would have happened? The resonance relation is created as a side effect of casting that spell?
