Hypostyle Hall
This Lake Mareotis temple to Sekhmet is home to one of Bayek's old friends, and to a number of quests.
An overlook above the front gate offers a fast-travel point.
The location goal is to find the Papyrus Riddle. Follow Senu's instincts to find it at a table of a balcony in the large hall.
This grants the 'Fertile Lands' riddle, and ends the mission.
