I’m making a city that’s run by demon crime families themed around the seven deadly sins.
The backstory I got so far is that long ago during the prohibition era, a cult successfully opens a gateway connected to Hell that covers the entire city. The 7 Princes of Hell sent their finest generals and thousands of demons to begin their takeover of earth. The 7 Generals and their first wave of soldiers managed to get reach the location where the portal had opened. But, before they could fully cross over into the mortal realm, the cultists lair was raided by the police, interrupting the ritual and caused an error in the gateway. The generals and their soldiers soon found themselves in a twisted hellish version of the city. The failed ritual had cut off the other demons in Hell and left those who were inside the gateway bound into a pocket dimension that they couldn’t leave. The demons had been completely cut off from Hell and the Cultists that started it all and knew the ritual were killed in the raid and all their knowledge was burned and no way to contact the princes. The 7 Generals realized that there was no way for them to get back to Hell. They knew that if they tried to takeover now the pocket dimension and the city would be annihilated by heaven’s forces.
So, the generals decided that they would have to find their own ways to survive and rule over this city in secret. They still had access to the humans city and can crossover between the two worlds as much as they pleased. So the demons started to disguise themselves as humans and started to slowly but surely to take over the cities criminal underworld. They got rid of the cities major crime families and took their places in secret. The 7 Generals soon became the seven crime families and ruled over the city with the angels in heaven none the wiser. The generals however didn’t all see eye to eye on how to run the city so they split up into 3 Syndicates. These Syndicates have the unions of Pride + Greed, Gluttony + Lust, and Wrath + Envy. Sloth has decided to remain a neutral party in this major conflict as they have decided to play the role of information brokers. The Syndicates have been fighting each other for years over whose sins have more control over the residents of the city.
The families have many demons and humans in their service. A large majority of the humans working for them have no idea they’re dealing with actual devils. However there are a select few who are completely loyal to the family who are gifted with the knowledge of their secrets. These people are known as warlocks and are granted special demonic powers themed after their new masters. The human on their side along with a few demons in disguise handle business in the normal version of the city, while the demons and warlocks do business on their demonic side. The demons can’t exit the city limits without being warped back inside and the warlocks lose their powers if the leave as well so the send the regular humans to handle any business out of town.
Right now i’m looking for ideas on what type of crimes they commit and what rackets do they run in the city. If you have any other questions about the city and how its world works or are confused about something please ask in the comments. I could use the writing practice.
