HPMOR Horcruxes are devices with a ghost attached. When touched, the ghost inhabits a victim and gives it the ghost's memories. But these victims are shallow copies of the original and easily dispatched.


"There will be no second date," said the green-lit silhouette in a voice so fearsome that it sounded, not only like a Death Eater, but like Amycus Carrow that one time just before Father told him to stop it, he wasn't the Dark Lord.


Sure bet that Carrow has a Riddle ghost inside him? No. But still, a possibility.

Subtle indeed. Conservation of detail might suggest that Amycus Carrow is going to play some sort of role involving dark rituals conducted in the past, but... is there an advantage to having a human Horcrux? I mean, its a lot less safe than all the other Horcruxes, but if if allowed Voldemort to posses Amycus Carrow then it would be useful.

I'd suggest not so much subtle as overinterpreting. Carrow is shallow-minded and status-driven, he thinks he'll sound more deatheaterish if he puts on a particularly grim voice, and Malfoy sees right through him and tells him to stop being silly. This is simple, compatible with everything else we're told, and sufficient to explain Draco's memory described here.

I'd agree - I doubt Carrow is a Horocrux, but the repeated mentions of him might indicate that he has some further role to play, possible involving dark rituals. But the joint probability (Carrow will appear) and (his role will involve dark rituals) and (dark ritual is a Horocrux) is quite low.

Also, IIRC there are 7 Horocruxes in cannon. In HPMOR, it is hinted that we have one for each greek element (magma, ocean trench, stratosphere and buried underground) and one in space. Presumably, Harry is one and Quirrel is one. So all Horocruxes are accounted for.

Joint probabilities don't work that way if you have a designed story line. Esp. by this author.

I'm sorry I don't understand. Even when discussing a work of fiction, the probability that 'Carrow has conducted a dark ritual which makes him a Horocrux' has to be strictly lower than the probability that 'Carrow has a further part to play'.

Probability doen't stop working in certain fields, its universal.

Comment author: Alsadius 01 February 2015 03:35:38AM 2 points [-]

Strictly lower, yes. "Quite low" was what you said, and that part can be disputed based on a read of the author.

Comment author: skeptical_lurker 01 February 2015 12:13:20PM 0 points [-]

Sure, if you think you have a really good read of the author. But as I said, all Horocruxes are accounted for, and as gjm said, there is a simpler explanation, and so I'm sticking by my opinion that Carrow probably isn't a Horocrux, even if he does show up later.

That sounds a lot more like a Rowling type twist than an Eliezer type twist. There are elements that could be interpreted as vague and oblique hints, but it doesn't suggest particularly clever or well-considered behavior on anyone's part.

"I see," said Professor Quirrell. "And what would you have done about the threat to me if your spell hadn't worked for destroying the Dementor?"

"Plan B," said Harry. "Encase the Dementor in dense metal with a high melting point, probably tungsten, drop it into an active volcano, and hope it ends up inside Earth's mantle. Ah, the whole planet is filled with molten lava under its surface -"

"Yes," said Professor Quirrell. "I know." The Defense Professor was wearing a very odd smile. "I really should have thought of that myself, all things considered."

(...)

"Oh?" said Professor Quirrell. "But there is an interesting pattern to them, you see. One might say it sounds like something of a riddle."

What Quirrell is remarking on is that Harry's following an elemental pattern, not that he himself followed the same one.

Q is saying that he didn't think of that as a thing to do with a Dementor and should have. One possible reason for his "very odd smile" is that he did already think of it as a thing to do with a horcrux. I think it's reasonable to call this a hint that maybe there is a Voldemort horcrux buried deep underground. (Certainly far from a proof that there is, though.)

Assuming those are horcruxes, not like parts of the Philosopher's stone or something (but Horcruxes are more likely).

Totally-not-going-to-happen reason for Hogwarts to stop playing with a snitch: the "air" horcurx is a snitch. Dumbledore realizes that Snitches are dangerous, and bans touching them. (Much more likely: Mcgonagall becomes headmistress).

Quirrell in Ch46 said they " sound like something of a riddle," which I guess could be interpreted to mean Tom Riddle, which may be evidence in favor of horcrux-status or something similar.

Comment author: skeptical_lurker 30 January 2015 03:00:26PM 1 point [-]

The entire world plays with a snitch. It seems very unlikely that any one school would stop playing with a snitch (and thereby ruin their preparation for games against other schools, adult competition etc).

But, if the whole of Hogwarts stops playing altogether, perhaps because the school has been destroyed, then technically they have stopped playing with a snitch.

The last act of whoever is the head (Dumbeldoor might have died) is to declare that in the last year of Hogwarts, all houses won the cup, as a symbolic act of unity in the face of tragedy.

Harry's wish was for quidditch to be played without a snitch. Not playing quidditch doesn't fulfill the wish.

Is the present king of France bald? I'm not sure where Quirrell and Harry stand on the truth of vacuous statements- if Hogwarts plays zero games of quidditch, all of them do not involve the snitch.

Also, technically Harry wished that "in Hogwarts we should play quidditch without the Snitch." Should can mean "will" but it can also mean Quirrell will somehow make it a moral fact that quidditch should be played that way, not a factual matter of actually playing that way.

is there an advantage to having a human Horcrux?

I believe so. Chapter 102:

Alsso Merlin'ss Interdict preventss powerful sspells from passing through ssuch a device, ssince it iss not truly alive.

By which I infer that if the horcrux is alive, you can pass powerful spells through it.

Also, that whole discussion simply screams of Quirrell setting Harry up for a ritual where Quirrell will transfer his mind to Harry's body, and set up shop there, the end.

Harry musing on what Q might have done to the Pioneer Plaque:

“Or... hm. A portrait seems to store a whole human brain’s worth of information... you couldn’t have added any extra mass to the probe, but maybe you could’ve turned an existing part into a portrait of yourself? Or you found a volunteer dying of a terminal illness, snuck them into nasa, and cast a spell to make sure their ghost ended up in the plaque.

Q later describing the Horcrux spell.

Horcrux sspell channelss death-bursst through casster, createss your own ghosst insstead of victim'ss, imprintss ghosst in sspecial device.

It seems another case where someone's musing turns up in detail later in the book. There are lots of these. Often, it just seems like EY foreshadowing (and possibly making the story nature of the events part of the plot), but in this case, it also seems very much like making up a lie that fits in with Harry's preconceptions.
