"Our organization was built to be flexible and fluid. There is no one supreme leader towering above us all, but a group of upper echelon members who come to democratic decisions about various matters."
"This is important, seeing as the organization is made up of members who have evolved with many different abilities. Each member is part of a sub-group under Supernatural that generally covers their field of abilities."
"So, there are Vampires, Werewolves, Undead, Ghosts and other such sub-groups. Please note these names aren't used to denote that each and every member of their sub-group possess that same ability."
"The power each person can awaken is always different. However, if person A has the ability to drain the life of another person while person B has the ability to use his blood to fight, they would both be placed under the Vampire sub-group, as it focuses on abilities derived from that terminology."
