The Sign of the Deathly Hallows
There's this weird symbol with an eye that keeps popping up around Harry, Hermione, and Ron. Is it the Illuminati? Will Harry, Hermione, and Ron get trapped in a tangled web of conspiracy theories and start saying, "Wake up, sheeple"?
Nope, sorry.
It takes basically the whole movie for them (and us) to find out that this little drawing represents those hallow-thingies mentioned in the title. Hey, better late than never, right?
The symbol basically consists of an eye, a triangle, and a line, and it symbolizes three objects that, when held together, could (according to legend) make the owner the "master of Death."
Those three objects? A resurrection stone, an invisibility cloak, and a very, very powerful wand.
Now, wizards like Ron had already heard the story of the Deathly Hallows in the form of a children's tale about the three brothers who were the original owners of the three objects—but it was told as just that, a tale. However, when Xenophilius Lovegood tells it to the ids, he seems to be dead serious about the existence and magical powers of these "Hallows."
When the movie ends, the kids don't seem sold on the existence of the Hallows, but they do know that Voldemort is after a super powerful wand. So maybe there's something to the tale?
And anyway, this whole notion of a foolproof way to master/cheat death is a little too appealing to ignore when they're trying to defeat the most dangerous dark wizard of all time.
So we're sure they'll still be mulling the existence of the Hallows—and their likely location—going into the next film.
