Knights of Mightguard

Protect the King and Queen, protect the People, protect the City, in that order. 
That's the first and most important rule for the Knights of Mightguard. The lesser needed rules are fairly standard, fight with honour and maintain chivalry, protect innocents and fight against great evils should they arise. The Order is prestigious, requiring years of training and trials to make it in, but once someone is accepted they are like family. Within Mightguard they will routinely run tournaments trying to find more who are worthy of joining them in their quest. They were first started after the great uprising to destroy the Evil king and queen link story here.
Sometimes the Order will send out small bands to roam to evaluate evil threat and get rid of them before they can grow. Thy often reuse to work with The Order of the Icewind Knights of Coldkeep as they find the mercenary work that they do distasteful and not as actually fighting off evil, only fighting for coin.
