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

The ancient artifacts in Assassin's Creed are called Pieces of Eden. They are fictional technological objects created by the Isu, an advanced civilization that existed before humanity's recorded history.

The Apple of Eden is the best-known example, but the series also features other forms, including Staves, Swords, and Shrouds. These objects can influence human perception, behavior, or physical conditions, making them central to conflicts between Assassins and Templars.

The artifacts are sometimes described simply as magical relics, but the franchise presents them as technology understood through a historical and science-fiction framework. The Isu are also called the First Civilization, and their surviving creations drive many modern-day and historical storylines.
