The Obsidian Order was formed in the 19th century, under the theoretical authority of the civilian Detapa Council. However, in practice it and the Central Command operated with complete autonomy. The Obsidian Order was responsible for matters of security and espionage, and was therefore forbidden from interfering in military operations. The Obsidian Order and the Central Command frequently came in conflict with each other, particularly since members of the Cardassian military were not immune to Obsidian Order inquiries. The only restriction that the Order had was that it was explicitly forbidden to possess military equipment of any kind. (DS9: "Defiant")
