"Of course it's my fault. There's no one else here who could be responsible for anything."

The first time this sentence appears in HPMoR is in the italic text that begins Chapter 2:

"Of course it was my fault. There's no one else here who could be responsible for anything."

I'll assume the difference between "it's" and "it was" isn't significant. I'm inclined to refocus my attention now on the italic text that begins Chapter 1:

Beneath the moonlight glints a tiny fragment of silver, a fraction of a line...

(black robes, falling)

...blood spills out in litres, and someone screams a word.

I didn't know what to make of this when I first read it, and I still don't. Does this describe an event that has already happened? It's not Hermione's death, since that didn't happen in the moonlight.

Does this describe an event that has already happened?

It's been debated constantly since the start because it's highlighted as important. The best guess was that it might have been when Voldemort attacked the Potters, but there's obvious problems with that (what's the silver? and as far as we know, no blood was shed by Voldemort since he favored AKs). Given that ch90 brings up blood as a powerful sacrificial element, it's looking more like it's about a future event and maybe a ritual by Harry - pursuant to bringing back Hermione being the obvious goal.

When you said AKs, I immediately thought you meant AK-47s. That put a very amusing picture in my head.

I might play too many videogames.

Comment author: Decius 02 July 2013 09:29:42PM 1 point [-]

They share many characteristics, don't they?

Comment author: Randaly 02 July 2013 04:28:17AM *  4 points [-]

what's the silver?

The only plot-significant things that have been described as silver are Fawkes, the Time-Turner, Dumbledore's beard, Lucius Malfoy's cane, and Patronus charms. I think we can safely eliminate Dumbledore's beard and Malfoy's cane. If it is in the future, I would have dismissed the time-turner before the past 2 chapters, but not anymore.

(I still believe it likely describes the attack on the Potters. Edit: I no longer believe this.)

"Beneath the moonlight glints a tiny fragment of silver, a fraction of a line..."

This sounds like an alchemy circle, which has to be drawn "to the fineness of a child's hair." I guess it involves the creation of a philosopher's stone.

Comment author: fubarobfusco 02 July 2013 05:34:34AM 1 point [-]

Or a horcrux? We still don't know what the ritual for that looks like.

Comment author: elharo 02 July 2013 10:39:33AM 2 points [-]

We know from canon and Word of Rowling that it involves murder, and is so disgusting it almost made her editor vomit.

Comment author: NancyLebovitz 02 July 2013 01:03:09PM 8 points [-]

Nitpick: "felt like vomiting" is well short of being almost made to vomit.

Comment author: tondwalkar 04 July 2013 03:17:17AM 1 point [-]

And if Yudkowsky's going to make a Fullmetal Alchemist reference, we know how to make a philosopher's stone, or even crude approximations, but only using human scarifice.

Comment author: hairyfigment 02 July 2013 08:48:18AM -1 points [-]

Could be alchemy or related magic used to turn someone's blood into a fake burned body. (Free transmutation seems easy to recognize.) But I've been thinking of it as an event in the past, which now seems dubious.

Comment author: Benito 02 July 2013 07:29:09AM *  8 points [-]

In the first Canon, unicorn's blood is silver, and that has a life-extension effect.

IIRC, Canon!Dumbledore says it is used as a last, terrible resort of a wretched life (or something).

Comment author: ikrase 02 July 2013 08:40:49AM 2 points [-]

In canon, it's also Unicorn blood.

It could also be Harry using Godric Gryffindor's sword to murder someone (Bellatrix?) in order to power the Summon Death ritual.

Comment author: Alsadius 02 July 2013 05:39:56PM 5 points [-]

I've always interpreted the Summon Death ritual to just create a dementor.

Comment author: Ritalin 02 July 2013 07:00:35PM 2 points [-]

That is completely out of character.

Comment author: Alsadius 03 July 2013 03:34:34AM 3 points [-]

Remember his anti-Batman resolution from a few chapters ago, where he said that a dead body means the gloves come off and he quits trying to fight a bloodless war.

Comment author: NihilCredo 04 July 2013 03:30:26AM 1 point [-]

Eliezer edited out his explicit resolution at some point before these updates began.

Comment author: Alsadius 04 July 2013 03:46:32AM *  2 points [-]

Noted. I think it's still a fairly accurate summary of his mental state, however.

Edit: Half of Ch. 85 is still basically in this vein.

Harry closed his eyes, swallowing hard a few times against the sudden choking sensation. It was abruptly very clear that while Harry was going around trying to live the ideals of the Enlightenment, Dumbledore was the one who'd actually fought in a war. Nonviolent ideals were cheap to hold if you were a scientist, living inside the Protego bubble cast by the police officers and soldiers whose actions you had the luxury to question. Albus Dumbledore seemed to have started out with ideals at least as strong as Harry's own, if not stronger; and Dumbledore hadn't gotten through his war without killing enemies and sacrificing friends.

Are you so much better than Haukelid and Dumbledore, Harry Potter, that you'll be able to fight without a single casualty? Even in the world of comic books, the only reason a superhero like Batman even looks successful is that the comic-book readers only notice when Important Named Characters die, not when the Joker shoots some random nameless bystander to show off his villainy. Batman is a murderer no less than the Joker, for all the lives the Joker took that Batman could've saved by killing him. That's what the man named Alastor was trying to tell Dumbledore, and afterward Dumbledore regretted having taken so long to change his mind. Are you really going to try to follow the path of the superhero, and never sacrifice a single piece or kill a single enemy?

Comment author: ikrase 02 July 2013 09:55:32PM 1 point [-]

<badass voice> Not anymore. </badass voice>.

Or he could just go all brutalist utilitarian.

Ooops. No. I mean more like Grindelvaldesque.

Would Harry have access to the sword, being a Ravenclaw?

Comment author: linkhyrule5 02 July 2013 06:04:27AM 0 points [-]

It could just be a random knife.

Comment author: Randaly 02 July 2013 06:17:55AM 2 points [-]

Possible, but unlikely.

Comment author: Velorien 02 July 2013 12:14:18PM 4 points [-]

The detail given could be that a knife is being used rather than a wand. And no-one we know would use a knife to kill rather than a wand unless there was a very special reason to do so.

Comment author: Decius 02 July 2013 09:28:43PM 0 points [-]

Unless they can't do magic...

Comment author: ChristianKl 02 July 2013 02:15:36PM -1 points [-]

An alternative to Harry doing the ritual would be that Harry get's sacrificed by a ritual of Quirrelmort to bring back Voldemort.

Given how much Harry trust Quirrelmort, it should be in Quirrelmort's power.

Comment author: loserthree 03 July 2013 02:52:29AM 0 points [-]

Harry doesn't trust Quirrell anymore, hasn't trusted him since the Azkaban arc. That was made pretty clear inthe conversation in the dark warehouse immediately after the raid.

If a drop of blood is all that's required to summon fire that can burn through the walls of hogwarts, then what can liters of blood do?

Comment author: gwern 02 July 2013 09:40:28PM 8 points [-]

Actually, it's not a drop of blood, it's a drop of blood for the rest of your life. But under a reasonable interpretation, Quirrel is perhaps being a little paranoid in avoiding use of that spell.

If we interpret the requirement as it frustrates one drop of blood from coming into creation, well, blood lasts ~120 days; if one drop is 0.05 ml and Quirrel is middle-aged and can expect another 40 years of life (the question about wizard lifespans is relevant here, though), then that's 0.05 * (365/120) * 40 = 6.1 milliliters total loss.

Or if we interpret it as reducing the total capacity of one's blood, well, adults have ~5 liters or 5000 milliliters, so you could use that spell hundreds of times before appreciably reducing your blood content (200 * 0.05ml = 10ml, so you'd go from 5000 to 4990...).

Comment author: Fermatastheorem 02 July 2013 11:37:06PM 3 points [-]

The latter explanation was my assumption. I am curious whether this capacity loss transfers across bodies when one is possessing someone else or has been resurrected.

Comment author: ikrase 02 July 2013 09:54:06PM 1 point [-]

IDK... Hermionie managed to shatter Hogwarts masonry with an explosive spell, and the Troll smashed it with a club.

Comment author: Michelle_Z 03 July 2013 01:32:49AM 0 points [-]

Good catch. That slipped my mind. :o

Though, apparently the castle will be "scarred"...?

Comment author: ikrase 03 July 2013 03:39:47AM 1 point [-]

Presumably the cursed fire prevents regeneration, means that mundane repairs (magical or mechanical) will not properly integrate, or something like that.

Comment author: Decius 02 July 2013 09:25:49PM 1 point [-]

Sacrificing liters of your own blood is more than enough to kill you.

Comment author: somervta 02 July 2013 02:49:55AM 5 points [-]

Note that of the italicized parts that appear at the start sporadically throughout the first ~20 chapters, this is now the only one that has not yet appeared later in the story (I went through and checked).

Comment author: Qiaochu_Yuan 02 July 2013 02:51:00AM 2 points [-]

I thought they would be in reverse chronological order or something cool like that, but no dice.

Comment author: loserthree 02 July 2013 03:22:56AM 2 points [-]

When you checked, did you record the chapter with the epigraph and the chapter where the line appeared in the text?

And if you did, would you share it?

Thanks!

So 1, 2, and 5 are the only chapters where the phrase doesn't appear in the chapter itself. Do those numbers mean anything recognizable?

EDIT: Yeah. 4. 1, 2, 4, and 5. Upvoting for correcting me.

Comment author: ShardPhoenix 02 July 2013 01:04:22PM 3 points [-]

And 4.

I did not for all of them, but I can easily reproduce it. One moment...

One of the only things I can recall being referred to as a line, is the Line of Merlin Unbroken - the short rod Dumbledore has when presiding over the Wizengamot. Of course, that's not silver...

EDIT: Just expanding; the Line seems to both refer to the physical object Dumbledore holds, but also the succession of people, going back to Merlin - making Dumbledore literally a fraction of a line.

Comment author: Alsadius 02 July 2013 02:59:49AM 2 points [-]

The first 20 chapters mostly have similar italicized bits at the top. Many have come to pass, but Ch. 1, the most mysterious of the lot, I do not believe has.

Comment author: elharo 02 July 2013 10:34:57AM 1 point [-]

Anything to be learned by correlating the chapters where they appear with the chapters with the quote? E.g. do later quotes appear earlier in the book? Or do the appearances of the quotes reinforce the lessons of the chapter where the quote appeared in some way?

Comment author: DanielLC 04 July 2013 06:54:58AM 1 point [-]

a tiny fragment of silver, a fraction of a line

A silver cord is commonly said to connect the spirit to the body during astral projection.

Considering that the closest we've seen to astral projection is Hoarcruxes, and they'd be pretty useless if they were that obvious, this doesn't seem like a likely explanation, but I still feel like throwing it out there.

Comment author: Tripitaka 03 July 2013 08:17:44PM 0 points [-]

There is another ritual we know of which could be described by the above:

Even so, the most terrible ritual known to me demands only a rope which has hanged a man and a sword which has slain a >woman; and that for a ritual which promised to summon Death itself

Of course there are obvious problems with the exact wording; and it is probable that this ritual just summons a dementor.
