Sure. Um...well the thoughts I have are:
1) Traveling thtough the forest alone, my character runs into some trouble. A knight (you) happens to see/hear something's wrong and come to investigate and go from there.
2) In a city protected by castle walls, my character is out on the streets in the dark, gets jumped and your character comes to save her to find most of the assailants knocked out or bruised though she still needs some help with the rest.
3) There is to be a great tournament and each knight is assigned a young woman to help them with their horses and/or introduce them in the tournament.
What do you think?
