For those who want to know, the pentegram is actually the "Seal of Solomon" the wise Hebrew king who used it's power to bind the efreet. When the seal is aligned properly, it is an ancient hebrew symbol of a wise and very holy king.
It is when it is inverted, that is supposedly being used for evil, which is true for nearly all christian and hebrew symbology.

And yes, I think a pentegram would make a nice target ring, espcially for wizards and magicians.
