In the world, there are many powerful entities that exist; all of which unknown to normal citizens. These entities come in many shapes, sizes, and personalities. But most of all, they come under many different aliases.
The most powerful of these entities are those that have, in response to limited human comprehension, adopted the title of "Gods". The creators. They have made it their duty to protect the human populace, though without alerting them to their presence. As such, they have given the human world a certain type of protector; those born with the ability of the arcane.
In exchange for this great power, these individuals are forced to heed the call of any and all who are in danger. When normal Law Enforcement agencies were established, they were given a break on answering to "menial crimes". However, they were then reassigned to tackling crimes of the Supernatural persuasion. They were powerful members of the Order.
The Enforcers; born to serve and protect those who cannot protect themselves.
Recently, however, many humans have begun to discover the secrets of the Enforcers; and many coups have been made with them. This caused a surge of renegade affiliations to surface, all of which lead to Enforcer on Human and Enforcer on Enforcer crimes. What was once the most closely bonded brother-sisterhood had become a chopped mess of an organization, split into teams of Enforcers looking out for themselves as individuals.
Now, humans that have been "educated" about their existence can never go back to what they once were.
