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.
I have heard (from an Afghan man that I know) that in Afghanistan, they will construct kites, and then tie or tape pieces of glass and shards of pottery to the kite-strings and have "kite-battles", where they try to use the sharp shards on their kite-strings to cut the opponent's strings.
