What fictional artifact can control minds in Assassin's Creed lore?

The Apple of Eden is the fictional artifact that can control minds in Assassin's Creed lore.

Apples of Eden are Pieces of Eden, advanced artifacts created by the Isu, an ancient civilization that existed before humanity's recorded history. Their technology can influence human perception and behavior, which explains the mind-control abilities associated with the apples.

The first Assassin's Creed game centers on an Apple recovered by the Templars and sought by Altaïr. Later games show additional Apples and expand the mythology surrounding the Isu and their relationship with humans.

The Apple is often confused with other Pieces of Eden, including the Staff, Swords, and Shrouds. These artifacts have different powers and story roles. The name is also a deliberate echo of the biblical forbidden fruit, although the games reinterpret it as a technological object rather than a religious artifact.
