For questions about the "Deathly Hallows" - three magical objects in the Harry Potter universe that together give the owner 'mastery over death'. Specifically, they are the Elder Wand, Resurrection Stone and Cloak of Invisibility. Note: This tag is for questions about the objects, not the book of the same name. Always use in conjunction with the [harry-potter] tag and any relevant tags.
The Deathly Hallows are three powerful objects, first mentioned in The Tale of Three Brothers, in the book Tales of Beedle the Bard.
The first Hallow is the Elder Wand, an immensely powerful wand that is passed from owner to owner by the previous owner being defeated.
The second Hallow is the Resurrection Stone, a stone that can bring back a remnant of a dead person. The Stone was passed down through the generations by the Gaunt family.
The third Hallow is the Invisibility Cloak, a cloak that can make the wearer completely invisible. The Cloak is currently in the possession of Harry Potter.
