Welcome to Chicago, the windy city, on the outside it's a hive of human activity, like any other city in the world, but Chicago has dark secrets. Four big dark secrets, in fact. the city is divided into four main territories, each owned by a family of mobsters, but these are not ordinary mobsters. on the north side of the city you have the Djinn Dynasty, a family of Djinn and Genies who use their magic to gain favor in both Chicagos political ordeals, and its crime underbelly. on the west side you have the Shifters, shapeshifting demon who use their power to create black mail, sneak into their enemies areas and spy on them, and even cause strife between the families. on the south side is the vampire den, drugs and money, that is all they care about. most of them are new bloods used as lamb to the slaughter to protect the real royalty. and on the East you'll find the werewolves. the pack in chicago has the curious position of having more money then they know what to do with, and are the newest to the area to become one of the top Chicago families.
(this is loosely based on the new bloodline spin-off from supernatural, although I haven't actually seen any of it so no prier knowledge of the series is needed, just know your monster. you don't have to be a Djinn, shapeshifter, vampire or a werewolf, but you will start at a low standing to the families until you prove yourself.
