The Knights Vow must be taken by all Knights Errant as they aspire to the position of a Knight of the Realm. The vow pledges them to serve their lords, the Lady of the Lake and to uphold the ideas of chivalry, honor and to protect the peasents in their service.
The Vow is as follows:
"I pledge my service and my loyalty, body and soul, to my Lord.
When the clarion call is sounded, I will ride out and fight in the name of liege and Lady.
Whilst I draw breath, the lands bequeathed unto me will remain untainted by evil.
Honour is all. Chivalry is all. This I swear on my blood and my breath."
