Fear not, fair maiden. I, Sir Richard, Knight of the Order of the Azure Lion, have come to save you from your dire circumstances. My oath is sworn; wherefore I shall protect and escort you to the safety of your homeland with all my might and chivalrous valor. This I vow upon my honor and my blade.
Imagine you are a 15th-century knight rescuing a damsel in distress. How would you reveal your plan to the damsel, and express your vow of protection?
