If something as simple as this can be considered a cartel, then the entire free market system is a cartel.
The whole point is that companies can only communicate with each other in this manner, and not directly, because that would be collusion.
When I have time, I'll look up the specific legislation, though i suspect it varies by area.
It isn't, but keep in mind that this is still a pseudo feudal system, which still has existent Noble families with laws favoring them on the books. In a feudal system, that is absolutely how a 'police' (private army) force actually works. If you're the Prince, you can command them. In such a system, it wouldn't seem as strange that the daughter of the house is giving the commands. You'll notice they also all announce themselves by House first.
As an aside, if you are Amelia Bones, and you have to give one person preferential treatment, control, and ease of communication with your Aurors (and by extension, yourself), who do you pick from the group of kids who are making the announcement? Which one do you trust most?
Because these are children who have been force-matured by both becoming (kind of fake) child soldiers and death, because the agreement specifically was created by two of said children, because all of the parents have other things to do, because the children are already there, because part of the theme of the first half of this story if you remember was "Children are people too, and not subhuman simply because of their age".
Susan Bones is giving the Aurors orders because it is her Aunt that runs the Auror office. She's basically the stand-in. The kids are the few actually sane people in Hogwarts.
Yes, that was my point, it's the True Patronus charm that is the exact opposite of AK, the Patronus Charm 1.0 is really a Dumbledore spell. It avoids fear of death by thinking about something else.
Our direct evidence doesn't completely pan out, because of the uncertainty of the Quirrel reaction, yes. But even without that we have evidence for the underlying theory: ie: AK is Death>Life: the spell and PC2.0 is Life>Death: the spell.
I can post quotes from both of these, in fact, I would argue that the Harry and Moody conversation on Avada Kedavra exists for the sole purpose of including that data in the narrative. Remember, these are Harry's words, a "magically expressed preference for death over life" and the Patronus Charm being cast by "rejecting death as the natural order."
But if say third years can, than ones who got their wands early may be able to. And it isn't all first years either.
Plus, it's more about the mindset than the actual ability.
Even ignoring the rest of the post, the idea of a Green Slytherin based off of Avada Kedavra is interesting for many reasons.
Let's look at some of the implications:
Avada Kedavra and the Patronus Charm (2.0) are basically mutually exclusive. In order to cast the first, you must want someone dead for the sake of being dead, and in order to cast the latter you must value all life to the point of denying death altogether.
Avada Kedavra and the Patronus Charm (2.0) cancel each other out. We saw this in Azkaban, and at the time we probably assumed it was just a result of Quirrell and Harry's magic going out of control, but on closer inspection it seems that both simply destroy the other, matter and antimatter style, which makes sense considering what type of magic they are created from. A magically created preference for death over life, and a magically created preference for life over death.
They both also follow the political lines, as you mention above. Avada Kedavra is more likely to be known and cast by those desperate for someone to hate, and the True Patronus is more likely to be cast by those who are trying to cooperate, simply because those mindsets are more likely to lead to those specific preferences.
Now that I think about it, the two groups are also the 'Cooperators' and the 'Defectors' in the Prisoner's Dilemma.
The interesting question is if they are going to devolve into standard Green vs Blue political idiocy. If Harry has a controlling power, they may not, but I don't think Draco has progressed enough as a rationalist to be able to avoid all those old lessons yet.
There is probably more here, but I need to sit down and think for five minutes, and do a quick read through of the archives.
In a previous story, EY posted the penultimate chapter along with an ultimatum: You will earn a Bad Ending by doing nothing, and a Good Ending by guessing, following the internal logic of the story, what the correct solution to this problem is.
The problem could be solved by combining a revelation in the latest chapter with information from an infodump in the first chapter, explaining how space travel worked in universe.
It was in fact solved, and he posted both endings.
This is the danger, that he may do the same thing here, and we must be ready to solve the problem.
I doubt it will be much of an issue however, the raw processing power we have to work with here is much higher, since HPMOR is much more popular than Three Worlds Collide.
Well, this chapter is just full of delicious puns, apart from the entire plot advancement thing.
Auxiliary Protective Special Committee.
Absurdly Powerful Student Council.
Daphne worried that Draco would be skinned and turned into Leather Pants.
Draco returns "at the turn of the tide" wearing white (silver) robes. He's Draco the White.. err.. Silver.
Considering the short length of the chapter, and combined with the call forward to Book V's Ministerial Education Decrees, that's a good number of references.
The real question is where does it go from here.
It would appear 0% of lesswrongers were born in May. Which is strange, because I seem to remember being born then, and also taking the survey.
