Till Death Do Us Part

Till Death Do Us Part was a virtual representation of one of Kassandra's genetic memories, relived by Layla Hassan through the portable Animus HR-8.5.

Riddle
''Atop Knossos Palace you will see a tree that shoots for the stars. But, like the love that lies at its roots, it'll never get that far. I hide away between bark and bone and curse the promises they made. Set me free at the foot of this tree, where with all their hearts they prayed.''

Outcome
Kassandra found and recovered the treasure.
