"As Marion sat atop the tower, hiding in the darkness, her bow and an arrow were ready across her knees. Her legs were numb with the cold seeping up from the roof tiles, and she inched slightly closer to the chimney. The heat emanating from it was as comfortable as the blanket her mother wrapped around her as a child, and her eyelids became heavy. Just then, the noise of horses sounded from below, and Marion was instantly awake. Her target was here."

Nock Markers or nocking points are designed to keep your arrow in place when you rest with your bow. It still releases the arrow as normal, but it allows you to move around and readjust without having to hold on to the arrow constantly. It is very useful when you have to be on guard and ready but cannot keep the pull of the bow the entire time.
