Nature's Way was a virtual representation of one of Bayek's genetic memories, relived by Layla Hassan through the portable Animus HR-8.
Bayek found the riddle in the Great Synagogue, at the north-western end of Alexandria, sitting on a table under a canopy.
In the east section of the Kanopos Nome is a ravaged land, where many trees fell and lost their home. I'm by the orphan tree whose parents fell down nearby, pointing toward their lonely daughter.
Bayek found and recovered the treasure.
