What are the ancient artifacts called in Assassin's Creed?

The ancient artifacts in Assassin's Creed are called Pieces of Eden.

In the series' mythology, the Pieces of Eden were created by the Isu, an advanced civilization that existed before recorded human history. The artifacts can possess extraordinary capabilities, including influence over perception, memory, and behavior, depending on the specific Piece.

The Apple of Eden is the best-known example, but the series also features other forms, including the Staff of Eden and the Sword of Eden. Different games place these objects in different historical contexts, where Assassins and Templars seek them for opposing reasons.

The name is sometimes confused with the Animus, but the two are not the same. The Animus is a modern machine used to access genetic memories, while Pieces of Eden are ancient in-world artifacts central to the conflict over control and human freedom.
