The Intelligence Authority are an intelligence service and law enforcement agency which operates in secrecy throughout the main city of Viden and in all of the outlying towns around the Bay of Synnefa. As a secret police organisation, they have little to no transparency, accountability or oversight, and they answer only to the Directorate (who, in turn, are loyal to Yvithia). A subsection of the Naval Force, the Intelligence Authority is given all of the standard tactical and combative training expected. The best are then offered the chance to gain training in intelligence, subterfuge, interrogation and related skills, in order to gain rank in the secret police.
Though the Intelligence Authority functions much a traditional organisation in a totalitarian state, Viden is not an authoritarian political city, nor is there a specifically autocratic regime. This secret police does not spy on the citizens and visitors of the city: they do not care whether or not the people love Yvithia. They do not exist to protect the political power of the current Directorate. They do not imprison people for disagreeing with the decisions and laws of the state.
The Intelligence Authority exists purely to protect the interests of the Directorate, the city and the Immortal Yvithia. Most often, this role ensures that the secrets that Viden wishes to protect remain just that: a secret. As has been the case since Treid's perceived abandonment, Yvithia's biggest fear is that the her beloved Facility for Retrospective Analysis (the half which researches the Great Shattering, not Treid's revival) will be revealed to the rest of Idalos (or even to the majority of Viden). As such, the primary duty of the Intelligence Authority is to maintain this secret above all others.
The Intelligence Authority are accountable only to the Directorate. They are specifically intended to operate above and beyond the law in order to suppress dissent or negative movements through clandestine acts of terror and intimidation (such as kidnapping, coercive interrogation, torture, internal exile, forced disappearance, and assassination). They operate partially in secrecy, that is, most of their operations are obscure and hidden from the general public, though a number of operants are known to the public. This capacity allows the Directorate to bolster some forms of necessary control over the citizens and visitors to Viden.
The Intelligence Agency has the traditional (and transparent) police authority to arrest and detain certain individuals as necessary. But in some cases they are given unsupervised control of the length of detention, and are given authority to decide and administer punishments independent of the normal operation of Videnese law. The organisation employs internal spies and civilian informants to find any who may act against Yvithia's goals. Secret police may intercept letters entering and leaving the city, check goods and cargo loads leaving the city, and stop any person entering or leaving, especially through a path less travelled.
People apprehended by the secret police are often arbitrarily arrested and detained without due process. While in detention, arrestees may be tortured or subjected to inhumane treatment. Suspects may not receive a public trial, and instead may be convicted in a fake, show trial, or by a secret tribunal. In times of emergency or war, the Directorate may lawfully and publicly grant the Intelligence Authority additional powers, which are designed to protect the city and its inhabitants.
