When humans first discovered our existence, they tried to shove us back into the shadows...
Impatient for humans to change they took over and created a hierarchy.
Humans bowed to their new masters... But where does that leave the rest of us?
The top of the hierarchy. Demons have a stranglehold on this city, from the red-light districts, mom and pop shops, and the politics.
Being second to the king comes with having the freedom to do almost whatever you want. Vampires run the slave market, blood dens and clubs in the city.
Humans can't even wipe their a** in the city without demons knowing about it. That being said, however, they sure are favored more than the other species.
Treated as second class citizens, wolves who are captured are sent to slave markets or made to serve in the military as dogs to their masters.
Treated as second class citizens, sirens who are captured are forced into the entertainment and escort industries. Forced to sing and dance and even attend special events as arm candy.
Treated as second class citizens, mermaids who are captured are sold into entertainment for circuses and freak shows.
Subservient to only Death, reapers have a hard time finding Lucifer's good side. Most slip by unnoticed, but those captured by demons are normally killed to serve as a warning to their creator.
Hunted by demons to near extinction, surviving angels have been sold to various industries in the city. By law, all angels must be branded with 666 on their wrists to show they are the property of demons.
Other species not on this list are too rare to place on the hierarchy.
Perhaps they can slip by in this city unnoticed...
