There are "Control Monster by voice" effects in game that many high end monsters have but rarely if ever do you see this ability used against a PC (In my case it was used as a plot device to set the mood for the current Dark elf plot). When I created the encounter that had this ability I had to have it perfect for it to even pass muster with JTF our head of plot at the time. Once he saw the finished module/encounter written he loved it and thought it to be very evil of me. After hearing how well it went he wished he could have seen it. I was very surprised at how it went and Rebecca really creeped me out at how well she played her NPC role. It was eerie and I was very on the edge that it could blowing up in my face if just one thing I didn't expect happened but I was glad that I took the time and made sure I had all my bases covered.
I'd also still like to thank all the NPC's who helped me pull this one off again.
