"Alright, well, some basic magical theory and practice then. A circle is often formed or cast, to designate a space. Often to keep something in, or something out. Casting the circle designates that space within the circle as 'special'. Often it's the first step in creating a ward or portal as well. When a circle is cast, one shouldn't break it--as bad things usually happen." Raven watched a moment to see if this explanation made sense. "So if I'm creating a circle with candles, I'm usually inside, and designating that space in the circle for a specific purpose I need to focus on, INSTEAD of focusing on the 'circle' itself."
