Features "The Grace" from THE SWORD OF TRUTH series of novels.  The Grace is drawn by those with magic.  The outer circle represents the beginnings of the infinity of the spirit world out beyond.  The square represents the boundary separating the spirit world -- the Underworld, the world of the dead -- from the inner circle, which represents the limits of the world of life.  In the center of it all is the star representing the Light, as the Creator.
