The Deathly Hallows are three distinct, immensely powerful magical objects that, according to wizarding legend, were created by Death itself. Each Hallow has a unique appearance and function. The three objects are represented by a symbol composed of a vertical line inside a circle, which is itself enclosed within a triangle. This symbol was famously worn by Gellert Grindelwald and later by Xenophilius Lovegood.
When united, the Hallows are said to make the possessor the Master of Death. However, the true meaning of this title is debated. While some, like Gellert Grindelwald, believed it granted invincibility, Albus Dumbledore and Harry Potter came to understand it as the wisdom to accept mortality rather than flee from it.
The origin of the Hallows is immortalized in The Tale of the Three Brothers, a story in The Tales of Beedle the Bard. The tale recounts how the three Peverell brothers used their magic to cross a dangerous river, cheating Death of new victims. An angered Death appeared and, feigning admiration, offered them each a reward.
Albus Dumbledore believed the Peverell brothers were simply exceptionally powerful wizards who created the items themselves. Over the centuries, the Hallows were separated.
The Deathly Hallows are the central MacGuffin and thematic core of the final book, Harry Potter and the Deathly Hallows. Initially, the trio's quest for Horcruxes is complicated by the legend of the Hallows, which Xenophilius Lovegood explains to them. The quest for the Hallows represents a tempting alternative to the difficult task of hunting Horcruxes. The Hallows serve as a profound thematic contrast to the Horcruxes. Where Voldemort fears death and seeks to conquer it by mutilating his soul, the story of the Hallows teaches that true mastery of death comes from accepting it. Harry Potter's ultimate triumph comes from understanding this distinction. He uses the Resurrection Stone not to live, but to find the courage to die. He becomes the true master of the Elder Wand through an act of non-lethal defeat, not murder. Ultimately, he chooses to keep only the Cloak of Invisibility, the Hallow of wisdom and humility, while discarding the Stone in the Forbidden Forest and intending to let the Elder Wand's power die with him.
