If you've ever heard of "Two Minds Think Alike" You haven't met these two. Double Marker is just two window markers fused together. They are like Yin-Yang, Sun and Moon, Fire and Water. Any opposite pair you could name. However they are both powerful without magic. The Red part of DOuble Marker is the good part. She is actually one of the kindest people you will ever meet. Not on Black's watch. Blakc is somewhat the opposite. The rudest person you could ever meet.
