In 16's files in Assassin's Creed 2 it identifies 4 different types of Pieces of Eden
- Apple – More commonly seen though the series
- Shroud – Shroud of Turin
- Staff – Seen in Assassin's Creed 2 and is apparently the Papal Staff
- Sword – The sword which Jeanne d'Arc used
also in Assassin's Creed 1, in the computer in the conference room it suggests that the Holy Grail is real and is a Piece of Eden.
16's files suggest that the Staff has the same ability to manipulate people as what the Apple has as apparently when the Czar lost the staff the people revolted against him, in the conference room computer it suggests that any Piece of Eden connected to the Jesus Mythos (Shroud, Holy Grail) will have the same powers as the Apple.
Since 16's files don't actually say what the Sword does, I am wondering if all the Pieces of Eden do the same thing.
