What ancient artifact is most often called the Apple of Eden in Assassin's Creed?

The artifact commonly called the Apple of Eden is a Piece of Eden.

In Assassin's Creed lore, Pieces of Eden are advanced artifacts created by the Isu, an ancient civilization that existed before recorded human history. The Apple is one of the best-known examples and is usually depicted as a glowing spherical object capable of influencing minds and producing powerful illusions.

The series uses the Apple to connect historical conflicts with its broader science-fiction mythology. Altaïr, Ezio, and other characters encounter different Pieces of Eden across separate time periods, although not every artifact has the same appearance or function.

“Apple of Eden” is a popular specific name, while “Piece of Eden” is the broader canonical category. It should not be confused with the Staff of Hermes, the Sword of Eden, or the Shroud of Eden, which are distinct Isu-related artifacts.
