To the Edge of the World

To the Edge of the World was a virtual representation of one of Kassandra's genetic memories, relived by Layla Hassan through the portable Animus HR-8.5.

Riddle
''From the Mastic Farm, follow the coast east. Keep going till the land's existence does cease. Tucked away in this cave, I watch sails go by. They left me here, to rest and to die.''

Outcome
Kassandra found and recovered the treasure.
