The being known as Death is the embodiment of the universal phenomenon marking the end of physical life, and may or may not literally exist. The best–known account of the entity is known as "The Tale of the Three Brothers", and was made famous by Beedle the Bard. According to this story, he was the one who witnessed the three Peverell brothers defy him by successfully crossing a deadly and dangerous river using magic. He was upset because he could not take them for his own, so he offered to give each brother an artefact of great power. The Peverell brothers chose the Elder Wand, Resurrection Stone, and the Cloak of Invisibility. These items later became known as the Deathly Hallows.
