The LotR we have been spared

The original idea for the movie trilogy envisaged a much greater role for Arwen and Eowyn. Sadly PJ backed down to the hysteria of fuddy duddies after the Fellowship of the Ring and Arwen was NOT at Helmsdeep, for instance. My desire is to write a fic making Arwen a 3D character and striking a balance between a BAMF and her gentle feminine side.
