The King's Citadel

According to the Book:

The King's Citadel is the highest law enforcement and paramilitary organization in Breland. In Sharn, they are called upon when a case is too big for the Watch to handle, especially if the case concerns espionage or national security. The Citadel directly serves Boranel ir'Wynarn through Boranel's younger brother Kor, who commands five captains for each of the five branches. The Citadel is explicitly a separate chain of command from the army, giving Boranel a much greater degree of control and discretion.
The elite agents of the Citadel operate in the interests and at the behest of the crown of Breland. Originally formed as an elite unit of spies and scouts during the Last War, the Citadel became the eyes, ears, and sword of Breland’s ruler. The Citadel operates throughout Breland as the ultimate agency for dispensing the King’s justice. Local watches and constabularies can call on its agents when a crime or situation poses a threat that spreads beyond their jurisdiction. Agents, on the other hand, can insert themselves into any situation they deem appropriate, since they wield the authority of the crown. The Citadel also conducts operations beyond Breland’s borders, gathering intelligence, performing covert missions, and vigilantly working to keep Breland safe from its enemies.
Part spy, part inquisitive, and part soldier, the agents of the Citadel serve crown and country with heart and soul. The agents have their oath and their duty to guide them, and they are expected to operate always with the good of Breland in mind.
Today the Citadel’s main headquarters can be found in Wroat, not far from Brokenblade Castle. The agency has another base of operations in Sharn, as well as numerous roving agents working throughout Breland and, discreetly, beyond the nation’s borders. Lord Kor ir’Wynarn commands the Citadel, assisted by the Citadel captains who each head up a division of the agency. For example, Captain Ellanar (female half-elf) leads the King’s Swords, a unit of elite warriors trained to undertake special missions. Other divisions include the King’s Shields (charged with protecting the king and his closest family members and associates), the King’s Wands (an elite unit of wizards and sorcerers), and the King’s Dark Lanterns (the intelligence branch of the Citadel).

The King's Swords
The King's Swords are a paramilitary group that executes on public missions within and outside of Breland. They are led by Captain Ellanar (female half-elf paladin).
The King's Shields
The King's Shields are charged with ensuring the personal security of members of the government. They are led by Captain Sortan (male human paladin)
The King's Wands
The King's Wands provide magical support for the other branches of the Citadel. They are led by Captain Nebik (male gnome wizard).
The King's Dark Lanterns
The Dark Lanterns serve the crown of Breland as the intelligence branch. They are led by Captain Vron (LN male changeling rogue). As the secret servants of the crown, members of the organization are granted the authority to conduct intelligence operations on foreign soil, execute covert missions across the globe, and prevent national secrets from falling into the hands of rival intelligence agencies. The Dark Lanterns also have the unwritten authority to eliminate any creature that threatens their nation, its sovereign, or its citizens. Once inducted into the Dark Lanterns, an agent is expected to serve until their death - While an agent may retire, the crown can recall them at any time.
The King's Shadows
The King's Shadows are an extra secretive division of the King's Citadel, only used for missions that must be kept as far from the government as possible. They are led by Captain Terra (female human ranger). Only the most seasoned, trusted, and elite agents are given the chance to join the Shadows
