What name is given to the ancient artifacts central to Assassin's Creed's mythology?

The ancient artifacts central to Assassin's Creed mythology are called Pieces of Eden.

In the series' fictional history, the Pieces of Eden were created by the Isu, an advanced civilization that existed before modern humans. These artifacts can produce extraordinary effects, including control over minds, illusions, and powerful energy phenomena. Their abilities help explain why Assassins and Templars repeatedly compete to find them.

The Apple of Eden is the best-known example, but it is only one type of Piece. Other examples include the Staff of Eden and the Sword of Eden. Their exact powers vary by artifact and story.

The term is often confused with the Apple of Eden, which is a specific artifact rather than the collective name. The series uses these objects to connect historical adventures with its science-fiction mythology.
