"Don't just laze about! Help with the seating arrangement! The guests will be here any minute, and the king said everything must be perfect tonight or heads will roll! Now remember, the King must sit at the head of the table with her majesty at his side. Lord and Lady Pemberton must sit next to each other but not next to either the Knight-Commander Gren or his wife.. The Priest Lenard mustn't sit next to any of the attractive Ladies, and the Matriarch will certainly cause a ruckus if not placed in a respectable seat, but don't put her near the wine fountain either. Also, the Ladies...."
A rumour of the knights of some powerful king that sleep until danger threatens the kingdom.
The truth is that they were rebels, trying to split the kingdom. Once captured they were put into an enchanted sleep, protected from age and harm, until their aims have been carried out by others in which case they will awaken.
There is a loophole in the spell in that trying to take one of their weapons will also awaken them.
