UNSC Directorate of Naval Intelligence Operations

The UNSC Directorate of Naval Intelligence Operations, colloquially known as the "Black Tower", was a division of the UNSC Central Directorate of Naval Intelligence (Section Zero) of the Office of Naval Intelligence, principally responsible for the command and control of all Naval Intelligence operations across the Milky Way Galaxy. It was a senior command, held by the Deputy Director of Naval Intelligence, and had a substantial responsibility of galaxy-wide coordination of ONI operations.

The division would become infamous for its colossal and mile-high skyscrapers that would become its lair on Asphodel Meadows in the 47 Ursae Majoris System; as ONI continually ascended in galactic influence, its domain of black citadels would continue expanding across Asphodel Meadows's surface, and eventually, the black balustrades of Naval Intelligence Operations would earn it an infamous moniker, the "Black Tower". All four major ONI directorates, the Directorate of Fleet Intelligence (Section One), the Directorate of Domestic Intelligence (Section Two), the Directorate of Special Intelligence (Section Three), and the Directorate of Strategic Intelligence, were responsible for reporting directly to Naval Intelligence Operations for deployment of agents and materiel, and for the prosecution of all operations. Operations that were not referred to Naval Intelligence Operations were subsequently investigated by the Naval Intelligence Department of Internal Affairs, therefore forcing all ONI subdivisions to adhere to the Black Tower as a central coordinating organ.
