Helios's Greeting

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

Riddle
''I lie within the shadows beneath Makedonia's lake, wading in her shallows, awaiting light's first break. When Helios beams through the arch in greeting, I am revealed and meet him, be it ever so fleeting.''

Outcome
Kassandra found and recovered the treasure.
