The Leaning Tower

The Leaning Tower 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 on the second floor of the Sarapeion of Karanis.

Riddle
''In Faiyum, north of Dionysias Caravanserai, there is a tower with a hole by its feet. It's in need of support, so I sit behind it, but the wooden beams seem more helpful''
