Could a Veela's allure override Amortentia, even just temporarily?

 

We have no canon source on this.

But to answer your question, I highly doubt that. Amortentia is said to be the most powerful love potion in the world (HBP).

 

Veela allure is fanon. In canon, we know:

1. Veela can make people lose their minds when they dance.

2. Veela are extremely beautiful.

The latter can make people say stupid things, just like people do IRL to impress people. As Veela are more beautiful than any normal woman, the things people say are correspondingly more idiotic.

But there is no evidence of mental influence power as standard. The way the mental influence was described during the dance scene was completely different to how the way Veela are described normally (flying to Jupiter scene), which simply induces spontaneous attempts to impress them in line with normal interaction with people you want to impress.

The idea that this is the result of direct magical influence on minds (allure), rather than magical enhancement of beauty itself, is compatible with canon but not necessitated by it.

 

People were prepared to jump to their deaths at the sight of them (if not death, then serious injury). I think that qualifies as maddening influence.

The link in OP goes to this thread.

 

The text implied a loss of inhibition, yeah, but conceivably you could even explain that as normal reaction to that level of beauty. It's hard for us to say as we've never seen it.

It's not hard to believe though. Compare how a group of drunk men reacts to a group of extremely attractive women. Now make those women supernaturally beautiful and doing a sexy dance.

 

Taure has it almost right, except that he forgot about Stan Shurpike and the Veela in the woods after the match. Let's go back to the pregame Veela showing first, however:

A bit later, the ref flexed before the Veela, which shows the same basic idea of trying to impress a Veela. Then, we see Stan Shurpike trumpeting his plans and future ambitions in the same manner.

So, while it is not expressly said that the Veela exibited control over others in a way that has become known as "allure" in fanfiction (note however, that allure includes so much more than what was in the books), it is most definitely canon that a Veela's very presence (the part Taure forgot about) can affect a wizard to start boasting, and their dancing can affect a wizard to do very stupid things.

 

I'd agree with that.

I'd also add that, in my opinion, a magical potion directly acting upon the brain, via its introduction into the body, trumps an effect that acts solely upon the mind, and does so from without (though a veela wouldn't have to negate or overwhelm the potion, just shift the focus of the potion's effects to herself...).

 

... I explicitely mentioned this. Twice.

 

And yet, doesn't the description of Harry's symptoms seem similar to the effect of the Imperius Curse? Both were detailed in the 4th book. In an 'epileptic trees' way, I could see the Curse being inspired by or even derived from the Veela's deadly-waves-of-stupidness powers.

EDIT: er, apologies for the conjecture that defies the rules of the thread. Next question, please.

 

Here's a simple canon question: how much non-verbal magic does Harry do in DH? Is there any indication that he's completely mastered it?

 

Completely mastered it in that he can cast every spell nonverbally? no.
Completely mastered it for a given subset of spells? yes.
Completely mastered it for every spell he knows? maybe.

 

I think JKR almost completely forgot the existence of non-verbal magic in DH. Even Levicorpus and its counter-curse, explicitly stated to be non-verbal in HBP, are used verbally by Hermione at Gringotts in DH.

It is implied in HBP that what while Harry struggles in non-verbal magic, he can use atleast some magic non-verbally in his classes. But he clearly doesn't have enough confidence in his skills to start using non-verbal curses in duels.

Whatever. It was still painful to read Harry struggle in the lone subject he ever excelled in at school, especially since it was taught by his most hated professor. But he did become head auror in canon. So yes, we can assumed he did master non-verbal dueling eventually.

 

Is there any canon justification for making Fawkes an actual intelligent being instead of, as Dumbledore explicitly calls him, a pet?

 

The Chamber of Secrets incident or being immortal for that matter?

 

The strongest evidence is Order of the Phoenix, where Fawkes gives Dumbledore the signal that Umbridge is distracted. That's a moderately complex task to perform.

So Fawkes certainly has a high level of intelligence for an animal, probably greater than even the smartest chimpanzees. How intelligent, however, is unknown.

 

Is there any canon evidence for phoenixes only associating with people of pure of heart/good? A lot of fics either have Dumbledore enslaving Fawkes to stop him running, or make it out to be that Dumbledore manufactured the myth of phoenixes only associating with light wizards.

 

Canon doesn't even have light wizards, and the other canon phoenix is a quidditch mascot.
The closest thing in canon is Fawkes's apparent ability to sense that Harry was in danger and loyal to Dumbledore and come to his aid. I was never quite clear on this. However, this is a preference for wizards who are as loyal to the domesticater as the phoenix is, not a preference for good or "light" wizards.
