Thoth's Secret was a virtual representation of one of Bayek's genetic memories, relived by Layla Hassan through the portable Animus HR-8.
Description
Bayek found the riddle within the Temple of Thoth in Hermopolis.
Riddle
Southeast of the city Hermopolis is a leopard's den in Uab Nome. At the top of their territory lies a place where birds should live, but do not. If you take a leap of faith, you can find me.
Outcome
Bayek found and recovered the treasure.
