Assassin's Creed Revelations Walkthrough Part 42 – Passing the Torch

The final Altair memory sequence begins here. It is very easy compared to what you have just dealt with and you get to use the Apple of Eden. Move forward, peroidically using the apple to subdue the various threats. When you reach the first part of the village, where Abbas pushed you off the ledge, climb the nearby building and use the Apple. After that, continue forward you will reach the final Waypoint Marker.

Altair passes on the Keys to Maysaf to one of the Polo Brothers. He tells him that they are keys meant for someone, but he does not know who. At least we know that Altair ended his life peacefully as Mentor to the Assassin's Order.
