The Eighty Sins of Sasamo
Some two hundred years ago, Princess Sasamo - the second daughter of her house - plotted to steal the throne from the rightful heir. Her conspiracy was found out before she could act, and she was arrested. Charged with high treason, she was made to walk the eighty steps just outside the city's gate eighty times a day for eighty straight days, With the final stride of her penance, she reached the last step and fell to the ground, dead.

Gate of the Sultana
Though erected in commemoration of Nanamo Ul Namo's reign, both the demand and funding to build it came from the city-state's merchants and Monetarists who were vexed at seeing passage through the city made nigh impossible by throngs of Calamity refugees. Thus, the Gate of the Sultana was constructed as a back entrance for the city guard, and now serves as a third egress from Ul'dah.
