The world is an extremely ugly place, especially for those living in the city of Chicago, Illinois. Nightfall heralds many dangers, and not just the usual risks of living in a city, such as rapes, murders, muggings, attacks, gang activity, abductions, and other crimes.
Chicago is a very large, very busy city, simply thriving with life at all hours of the day and night, and that makes it the perfect hunting ground for the creatures of darkness... demons, as they are more commonly known as. Humans are not only being threatened by the day to day aspects of city life, but by the forces of Hell.
However, some humans are luckier than others. Those who are chosen, those who will go on to do something great with their lives or change the course of history, are constantly being watched over by creatures of the light. Angels. These guardians protect the humans they have been assigned to with every fiber of their being. They have a certain bond between themselves and their charges, a bond which cannot be ignored or broken.
Some angels, however, are unlucky. Some fail in their mission to protect, some give into human temptation, some simply refuse to acknowledge their duties and rebel against what they are supposed to stand for. These angels, these fallen angels, become what we today refer to as "vampires". Creatures of the darkness who prey on the living, undead and terrified of anything holy.
The city of Chicago has become home to many of these demons, angels, and vampires, and a battle between darkness and light is finally on the brink of becoming a full-fledged war. The only question is... which side are you on?
