Whence comes the word Court, and its relatives: courtliness, courtesy, courtier, to court, a curtsy, and courteously? All point to a certain way of relating. Can you see the Royal Blood in the person next to you, even if their clothes look torn and dirty? Can you elevate every day life by offering dignity and respect usually reserved for those of the highest station?
In the space of the Queen’s and King’s Court, all Nobles (the players), in consenting to their new elevated status, also consent to a higher level of speech.
How the Nobles do this remains up to them and the Host of the Court. For inspiration, they may read famous rhetorical works; whether political (like the Declaration of Independence), literary (as in the works of Shakespeare), or poetical and multilayered (like the Tzutujil Maya’s spoken traditions as recorded in Martin Prechtel’s Long Life, Honey in the Heart). Wherever they find a style to key off of, they can run with it, as long as it sounds regal (or at least aims to sound regal). If you fear to fail, don’t worry; aim (in the words of Martin Prechtel) to Fail Magnificently!
Owing to that, the Host and the assembly all encourage one-upmanship and over-the-top speechifying, learning from each other and keeping the stuff that they like the best for the next session of Court.
