Ashes to Ashes (Ainigmata Ostraka)

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

Riddle
''When times are bad, it can be easy to turn away from the gods. Go to the burned temple in Kausos Village, in the Cursed Valley of Pali. I can be found in a pile of burning ashes, where a worshiping man left his post to begin his new life as a pirate.''

Outcome
Kassandra found and recovered the treasure.
