The Gryphon Knights are the commanders of the Sovereign’s Finest, the King’s loyal advisors and bodyguards.
The Sovereign’s Finest is The Crown’s Personal Unit. They are not only elite fighters who have distinguished themselves in service to the Country (Caladania), but they are trained to be envoys of the crown and capable of special duties.
Sovereign’s Swords are the distinctive weapons of the Sovereign’s Finest, the upper ranked members of the Kingdom’s forces. These special agents are the Sovereign’s hands, imparting justice and rulings when needed, being embassy, or doing special duties.
It is not considered a crime if a ship's crew mutinies against a captain that is obviously unfit for the post (dangerously incompetent, insane, or overly cruel). Assuming, of course, that they can prove it.
