What is the name of the Apple of Eden in Assassin's Creed's Isu artifact numbering?

The Apple of Eden is designated Piece of Eden 2 in Assassin's Creed's artifact numbering.

In the series' fictional mythology, Pieces of Eden are advanced artifacts created by the Isu, an ancient civilization that existed before humanity's recorded history. The Apple is usually depicted as a small, glowing sphere capable of influencing human minds and producing other extraordinary effects.

Multiple Apples appear across the franchise, so “the Apple of Eden” is not necessarily one single physical object. The numbering system distinguishes artifacts in the wider collection, while individual games show different Apples in different historical periods. This is why the Apple can appear in stories involving Altaïr, Ezio, and other characters.

The Apple is commonly confused with the Staff of Eden, the Sword of Eden, or the Shroud of Eden. Those are separate Pieces of Eden with different forms and functions. The artifact's fictional powers are not historical claims; the games place this science-fiction mythology inside otherwise recognizable historical settings.
