The Deathly Hallows are, perhaps, some of the most important magical artifacts in the
The Deathly Hallows are comprised of three symbols, each standing for a different magical artifact: the Cloak of Invisibility, the Resurrection Stone and the Elder Wand.
At different points, Dumbledore possessed all three Deathly Hallows. He won the Elder Wand from Grindelwald, had the Invisibility Cloak in his possession when James Potter died, and wore the Resurrection Stone as it sat in Marvolo Gaunt's ring.
Harry is not immortal because he owns all three of the Deathly Hallows and becomes master of death; he is master of death because he accepts his mortality.
Dumbledore, at one point, possessed all three Deathly Hallows.
Albus Dumbledore and Harry Potter were the only known people to have held each of the three Hallows, although neither possessed all three simultaneously (the closest was Harry being the Elder Wand's master, though not in physical possession of it, while having both the Stone and the Cloak in his physical possession).
James inherited the cloak from his father, Fleamont Potter, who inherited it as a descendant of Iolanthe Peverell -- a granddaughter of Ignotus Peverell. The cloak passed down through generations of the family until it reached James and then Harry.
The three Deathly Hallows – the Invisibility Cloak, the Resurrection Stone and the Elder Wand – have tempted many a wizard over the years.
Voldemort wasn't aware of Harry being a pseudo-horcrux because he didn't plan it, and Harry didn't know either until Voldemort killed him, but he actually killed the piece of soul kept in him. It was an anonymous present waiting for him on Christmas morning. How did Dumbledore get the cloak of invisibility?
The big “secret” about the Dumbeldore family that the title promises is actually an explanation of the last film's cliffhanger. Albus confirms to Creedence early on in the film that he is in fact a Dumbledore, quashing any rumor that Grindelwald had lied to the young boy in order to sway him to his movement.
At its core was the Resurrection Stone – the Deathly Hallow once owned by Cadmus Peverell. The ring was hidden in the remains of the Gaunt family shack, and the defensive spells placed around it had to be overcome by a very powerful wizard.
"Dumbledore fell in love with Grindelwald" and was "blinded" by it. "This was Dumbledore's tragedy."
Voldemort intentionally made six Horcruxes, but when he used Avada Kedavra on Harry, he unintentionally created a seventh Horcrux. Instead of dying, Lily's love for Harry created a counter 'curse' known as Sacrificial Protection and saved Harry.
Dumbledore left Harry the Resurrection Stone (disguised in a Snitch) in his will, and Harry uses it just before he goes to battle Voldemort. However, he doesn't use it to try to bring the dead back for an extended period or anything.
Harry inherits the invisibility cloak from his father, which was passed down through the generations from the third brother, Ignotus Peverell. Harry is also the only descendent of the Potter family still alive, and so is the only known descendent of Ignotus that we know of.
These wizards can see invisible creatures. Sound familiar? Dumbledore knew Harry and Ron were under the invisibility cloak at Hagrid's hut in Harry Potter and the Chamber of Secrets, as his eyes flickered in their direction.
Additionally, in Harry Potter and the Chamber of Secrets, Professor Dumbledore looks right at Harry and Ron underneath the Invisibility Cloak while in Hagrid's hut, suggesting that Dumbledore might actually be able to see through the Invisibility Cloak.
"Linfred was a vague and absent-minded fellow whose Muggle neighbours often called upon his medicinal services," Rowling explained. It was these "medicinal services," including "Skele-gro" and "Pepper Potion," that were the beginnings of the Potter family fortune.
Why did Dumbledore give Harry the Ressurection stone? But the Resurrection Stone DOES serve a purpose. Right before Harry walks into the enemy camp to put an end to the battle, the Stone gives him exactly what he needed to steel his resolve – comforting last words from his parents, Sirius and Lupin.
However it seems that Dumbledore eventually disclosed the cloak to Snape and possibly other teachers, as Snape knew Harry was in possession of the cloak in Prisoner of Azkaban, when Malfoy reported the apparent apparition of Harry's floating head outside the Shrieking Shack, which Snape immediately understood to be ...
While in school together, Sirius once tricked Snape into almost entering the Shrieking Shack while Lupin was there, transformed into a werewolf. James realised the danger and stopped Snape, saving his life; this is the incident Dumbledore referred to at the end of the first book.
Dumbledore lived that long because he was in posession of the elder wand (a wand worthy of someone who had outsmarted Death. According to legend, whoever united the wand with the other two Hallows (the Resurrection Stone and the Cloak of Invisibility) would become the Master of Death.)
Dumbledore knew for sure that the cave is going to be very dangerous, but he didn't know if he and Harry will be able to get the horcrux. So if they had carried the sword with them, they would have taken a great risk.
Dumbledore was never obsessed with the hallows. He was just aware of the fact that it could be a potential threat to the entire world if fallen into the wrong hands. He had already witnessed how dangerous only 1 of the deathly hallows was in the wrong hand- In Grindlewald's hand.
