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.
Pirates' many bejeweled rings and piercings actually had a practical purpose - when the pirate or sailor died, the rings could be taken off as payment for a proper burial, saving him from a watery grave. This could be tied into regional culture, or made into a quest (The Pirate's Lost Rings, etc.). Also gives treasure-seeking divers another thing to look for besides crusty old chests.
