What name is given to the ancient artifacts often sought in Assassin's Creed?

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

Pieces of Eden are advanced artifacts created by the Isu, the precursor civilization known in older games as the First Civilization. They possess extraordinary abilities and are repeatedly connected to the long conflict between the Assassins and the Templars.

The Apple of Eden is the most famous example, but the wider category includes multiple artifacts with different powers. Depending on the game, Pieces of Eden can influence minds, generate illusions, or perform other effects that later cultures interpret as supernatural.

They are fictional devices within the series, not historical relics. The games place them inside stories involving real locations and historical figures, which can make the artifacts seem like adaptations of actual mythology. Their recurring role is to connect the modern-day narrative with events from the distant past.
