The player needs to get to know everyone in the city and get to the bottom of the mysterious Golden Rule while trying not to commit any sins of their own.

In exchange, they'll be sent back to their own time. He tasks the player with finding out who's doing it and stopping them. The player eventually discovers that the ruler of the city, Magistrate Sentius, has been resetting the world every night because, no matter what, someone commits a sin and everyone turns to gold. If the idea of not committing a 'sin' sounds vague, The Forgotten City asks a lot of questions regarding individual morality, the morality of only following rules out of fear, and the definitions of what constitutes a sin. As a result, the town lives in fear that someone, somewhere, will commit a sin and doom everyone. As they meet and get to know some of the 22 occupants of the town, the player discovers that everyone lives under a system called 'the Golden Rule,' which is that 'the many shall suffer for the sins of the one.' Essentially, everyone has been told that if they commit a sin, they'll all be turned to gold and killed instantly. Originating as a Skyrim mod before becoming a standalone experience, The Forgotten City is about a person from the modern day who magically enters an ancient Roman city.
