White Council

The White Council is the governing body of the Wizard community in the world. They primarily protect humanity from abuses of magic, but also shield this world from the Sidhe and other creatures that wish humanity harm. It is also a political and democratic organization seeking to unite wizards throughout the world, and can make or break treaties with the other supernatural powers as necessary. Due to the multitude of nationalities present, meetings of the Council are traditionally conducted in Latin, a procedural point which has, not coincidentally, served to keep younger wizards from gaining too much standing or momentum by making it very difficult for them to speak eloquently or even coherently to the rest of the Council. The council meetings' dress code imposes wizards to wear robes. Wizards and apprentices are differentiated by the color of their robes: black and brown respectively. In addition, full wizards wear a stole.
The Council is governed by a Senior Council of seven wizards, with the leader referred to as the Merlin. Beyond the Senior Council, which constitutes the executive branch, there are the actual wizards of the council that contribute to the legislative branch. The Judicial branch belongs to the Wardens, a combination police force and military. -Wikipedia
