Death (The Tale of the Three Brothers)

According to The Tales of Beedle the Bard, it was Death who, witnessing the three Peverell brothers defy him by successfully crossing a deadly river, offered to give them each an artifact of great power. These items, the Elder Wand, Resurrection Stone, and the Cloak of Invisibility, became known as the Deathly Hallows.

Albus Dumbledore, however, speculated that these artifacts weren't really given by Death, but were instead created by the very powerful Peverell brothers.
