And the title of book seven is... (SPOILERS)

[PhantomoftheFox]

Dum da da dum!

Harry Potter and the Deathly Hallows.

So if this guild is still alive... thoughts? Like? Dislike? And what the heck is a 'deathly hallow' anyway?

Every other part of the series has used the title of a place, object or person that is first introduced and features prominently in that book.

Deathly;
1. having the physical appearance of death; "a deathly pallor"
2. causing or capable of causing death

Hallow;
1. to make holy; sanctify; consecrate.
2. 'All Hallows' Eve', also known as Halloween or Hallowe'en.

The most obvious possibility is something to do with or on Halloween, since that date already has a very important part in the series, but that would be a bit of an aberration from the rest of the books; none of the titles have used dates or times before.

It doesn't seem likely to be a person, so a thing or a place...
There are also a number of churches in London with 'Hallows' or 'All-Hallows' in the name; is it possible that a part of the book could take place in one of them?

As for a thing... A 'deathly hallow' sounds rather like a dark sacrament- the first thing that comes to mind is some sort of spell or ritual. (Possibly the spell used to create horcruxes?)

OOOOOH! I KNOW!!! (At least, I think I know...)

Well, it is the end of the book series, and either Harry or Voldemort has to die, right? Well, unless J.K. Rowling decided to be an idiot and not have either of them die and leave everyone dissaspointed on a forever-looming cliffhanger like Lemony Snicket did with his Series of Unfortunate Events, but I doubt that... I think the title might predict where whoever dies dies. Or, in essence, where the "final battle" takes place.

WORK WITH ME HERE! Do you have any idea where I am talking about? Hollows? That's right, Godric's Hollow! You know,

Harry travels far and wide
With his companions by his side
Searching for horcruxes wherever he goes
But where the last one is nobody knows
So back in Godric's Hollow he lands
Just to find himself in Voldemort's hands
A final conflictment then breaks out
And one enemy dies with a final shout.

Am I brilliant or am I brilliant? (Modest, too...)

And, if this fails to be true, I think that the book would have something to do with Harry being in Godric's Hollow, seeing as it is 'deathly' because Harry's Parents died there. Maybe he searches for clues or soemthing... I still think that the first one is more likely to be true.
