The Guild is a multi-racial police force charged with the protection of humanity. The organisation was formed in 1947 after the formation of the Grand Alliance during the fallout of WW2. The idea was that the Guild would protect the newly identified other races, as well as humanity, from all that would do them harm. The officers of the Guild follow the international laws as directed by the Grand Alliance, and have the power to prosecute anyone breaking those laws.
The Guild operates from Guild Houses situated in various locations throughout the countries of the Alliance. They enact their own investigation into the supernatural as well as advising local police and government agencies on how to handle non-human races. If a hospital has a question of Werewolf physiology to treat a patient of flu, they call the Guild House. If a Vampire needs to change the address of their blood delivery, they call the Guild House.
The Head House is the Guild’s main base of operation in a country, and contains everything the Guild would need. This includes laboratories, hospital facilities, arcane libraries and armouries, as well as a huge amount of administrators and clerks who sort and file the vast amount of paper work. It is also the location of each head of the Guild’s various departments.
The Criminal Investigation Department (CID) is the main branch of the Guild. They deal with a huge array of crimes including murder, theft, magical sabotage and illegal blood drives. They also act as advisers to local police and detectives, but with take over any case they believe falls into the jurisdiction of the Guild. Most beat cops of the Guild are agents of this department.
The officers of the Werewolf, Vampire and Risen Affairs Agency (WAA, VAA and RAA respectively) deal with racial specific and cultural matters. This includes Agent Resources for members of the Guild, as well as matters of culture, heritage and crimes directly relating to the breaking of the rights granted by the Grand Alliance.
Internal Affairs (IA) deal with corruption, breach of protocol and illegal activities by enacted by the Guild itself. Even an organisation with such high ideals as the Guild is not exempt from corruption within its ranks and all officers are on edge when the IA show up in their Guild House.
The Department of Arcane and Existential Investigation and Research (DAEIR) are some of the most gifted people of the Guild. They investigate ancient laws, research magical theories and keep the histories in the country's Master Library located at the Head House. They are masters of lore, and use their extensive knowledge of the arcane to solve magical crimes; to the bane of all would be spell-thieves.
Crime Scene Investigations (CSI) is the scientific and alchemical department of the Guild, and is called into a crime scene to gain insight into a case. They work closely with the DAEIR to gain enough evidence to prosecute criminals and solve cases.
Supernatural Weapons and Tactics (SWAT) are the ones you call when everything has gone wrong. Trained in all manner of combat situations, they are the first through the door and the last out. They also function as riot police and weapons experts, as well as strategists for different operations.
A Guild Cell with often comprise of CID officers, backed up by others from various departments. The Cells are formed when different Guild members come to gather to police a certain area, or crack a certain case. Most officers work solo or in pairs as and when the Guild orders them to, moving from Guild House to Guild House depending on the work.
